grade (10)

Tough people need tougher weapons. A military grade laptop or rugged laptop is one such tough weapon that assist our brave hearts through thick and thin. Military grade devices pass vigorous testing standard MIL-STD that ensures that these devices can endure any altitude, extreme temperature, humidity, jolts and shocks. Rugged electronics thus can withstand wear and tear that normal devices seldom can. Let’s go through 3 of such toughest professions that makes use of military grade laptop and military grade tablets.

In the battlefields

Military grade devices have longer battery life and daylight readable screens that are the typical attributes needed in a battlefield. These laptops are used for many functions on the battlefields:

1. Communication - The embedded mobile connectivity features of rugged electronics enable the soldiers to communicate and update location with each other.

2. Awareness about the surroundings - Fitted with cameras and locator software along with the data feeds from satellites and drones, military grade devices provide a complete situational awareness.

3. Mapping the terrain - Military grade device’s great memory assists the military surveyors to map accurate battlefield terrains. High processing speeds and connectivity also enables the data collection to generate maps.

4. Combat medical aid - High storage and super-connectivity feature also aid in the battle related medical emergencies.

Emergency medical services

Medical emergencies caused due to nature furies or accidents are the situations when a rugged electronic device becomes a savior. The first responders and paramedics depend heavily on laptops for recording, monitoring and sharing patient’s information. The accidental site may be too rugged because of the mishap and normal laptops may be inefficient to work under those distress situation. A military grade laptop or a military grade tablet comes in handy for the medical professionals because of the following features:

• Shock and drop resistant rugged devices improve the durability.
• Touch screens aids in capturing signature for consent forms.
• Military grade devices can be mounted on vehicles.
• Secure and fast connectivity helps in sharing of patient’s medical details.

Factory and Construction floors

Laptops are an inevitable item for engineers who rely considerably on it for variety of information at a construction site. Construction sites are always laden with dust and debris and there might be many shocks and vibrations. Hence, carrying project related vital information on a non-rugged laptop may be a disaster. It will be sensible to use military grade devices in construction sites since these devices have undergone various shock testing.

The difference between 5052 and 5083Both 5052 and 5083 are Marine grade aluminum, and the metal content, especially the Mn and Mg content, is very different, and the 5083 has a higher tensile strength and yield strength than the 5052.Si Fe Cu Mn Mg Cr Zn5052 0+ 0.4 0.2 0.2 0.5-1.1 0.1 0.255083 0.4 0.4 0.1 0.3-1.0 4.0-4.9 0.05-0.25 0.25Five series: 5000 series aluminum alloy represents 5052, 5005, 5083, 5A05 series. The weight of the aluminum-magnesium alloy is lower than the other series under the same area. It is also widely used in conventional industries. In China, 5000 (such as 5005) series of aluminum plates belong to one of the more mature aluminum plate series. The main features are low density, high tensile strength, high elongation and good fatigue strength, but they cannot be heat treated.5052 has good formability, corrosion resistance, candle resistance, fatigue strength and moderate static strength. Used in the manufacture of aircraft fuel tanks, oil pipes, as well as transportation vehicles, ship sheet metal parts, instruments, street lamp brackets and rivets, hardware products.5083 is used in applications requiring high corrosion resistance, good weldability and moderate strength, such as ship, automotive and aircraft welded parts, pressure vessels requiring strict fire protection, refrigeration units, TV towers, drilling equipment, transportation Equipment, missile components, armor, etc.0, HThe prototype aluminum alloys are subjected to different heat treatments to obtain different hardness classification standards. This is an explanation of ANSI H35.1, which is mostly followed in China. There are five basic states of aluminum alloy:F, free processing state: suitable for products with special requirements for work hardening and heat treatment conditions during the molding process, the mechanical properties of the product are not specified.O, the annealing state is suitable: for the finished product obtained by complete annealing to obtain the lowest strength.H, work hardening state: It is suitable for products which are strengthened by work hardening, and the product can be subjected to additional heat treatment after the work hardening can be passed (or not) to reduce the strength. The H code is followed by two or three Arabic numerals.W, solid solution heat treatment state: an unstable state, only applicable to alloys which are naturally aged at room temperature after solution heat treatment, and the state code only indicates that the product is in the natural aging stage.T, heat treatment state: (different from F, O, H state) is suitable for products that have been stabilized after (or not subjected to) work hardening after heat treatment. The T code must be followed by one or more Arabic digits.H state subdivisionH1: only indicates the work hardening state, and is suitable for products that have been subjected to work hardening without heat treatment to obtain a specified strength;H2: Work hardened and incompletely annealed, suitable for products where the degree of work hardening exceeds the specified requirements, but the strength is reduced to the specified requirements after incomplete annealing. For alloys softened at room temperature, the minimum tensile strength of H2 state is The H3 state is the same. For other alloys, the minimum tensile strength of the H2 state is the same as the H1 state, except that the elongation is slightly higher.H3: Work hardening and stabilization, suitable for products that have been subjected to low temperature heat treatment after work hardening or mechanical properties due to thermal effects during hot working. Stabilization usually improves ductility. This code is only suitable for aging softening at room temperature. Alloy.The H1, H2, and H3 state codes are followed by an Arabic numeral indicating the degree of work hardening. Numeral 8 indicates the final tensile strength obtained after about 75% cold deformation (processing temperature not exceeding 50 ° C) after complete annealing. The states of the O state and the number 8 are indicated by the numbers 1-7, respectively.The third Arabic digit is used when there is a difference in the degree of control or mechanical properties (or both) of the HXX state, or when other characteristics are determined to have a significant effect. For example: HX11 is suitable for products with sufficient work hardening if the final annealing does not reach the annealing state, but the degree of work hardening is not completely consistent with the HX1 state; H112 pure work hardening state, degree of work hardening or annealing degree Unadjusted, suitable for products that have certain properties during thermal processing. These products have mechanical properties and are generally extruded.For more information about Marine grade aluminum, please pay attention to our website.

Marine engineering includes not only ships and ships, water and underwater facilities, but also various buildings and facilities related to marine work on the shore and in the port. The most resistant to seawater is the 5 series alloy, followed by the 1 series and 3 series alloys. Therefore, the preferred material for the design of Marine Grade Aluminum is Al-Mg (5 series) alloy. The performance of the 5 series alloy cannot meet the design. Use other alloys when required. Recent studies have shown that individual 7-series alloys, such as China's 7A33 alloy and the United States' 7033 alloy, are highly resistant to seawater and become a rare up-and-coming marine engineering alloy.

Al-Mg alloys can be divided into two major categories: alloys containing Mg ≥ 4% are called hard alloys, and alloys containing <4% Mg are called soft alloys. Alloys containing >5% of Mg are rarely used in cold working because they are sensitive to stress corrosion cracking and should be applied after stress relief annealing (stabilization). Stress relief annealing has little effect on the mechanical properties of the material, but it can greatly reduce the stress corrosion sensitivity.


The electrode potential of an industrial aluminum-magnesium alloy is the same as that of a high-purity alloy: zinc increases the potential, copper lowers the potential, and other elements have little effect on the potential of the Al-Mg alloy. Industrial Al-Mg alloys have the same corrosion resistance as high-purity aluminum; elements that lower the potential, even those with reduced corrosion resistance, are impurities with very little content, and the influence on corrosion resistance is negligible, so aluminum - Magnesium alloys have excellent corrosion resistance in the following conditions: for ordinary atmosphere, water, steam, sea water, marine climate, and many chemical products. Analysis of corrosion products containing 5% Mg alloy revealed mainly Al2O3 with a small amount of Mg.


Industrial Al-Mg alloys also have intergranular corrosion and stress corrosion cracking sensitivity, but are closely related to the structure. Therefore, the sensitivity after aging at 127 ° C ~ 225 ° C for aging or stress relief annealing is comparable to that when exposed to tropical climatic conditions or long-term storage at room temperature, stabilized at 127 ° C ~ 177 ° C for 24 h or at 225 The sensitivity to these two corrosions can be eliminated by treating at °C~275°C for 10min~20min.

Cu and Ni promote pitting corrosion of 5 series alloys. Fe and Si also have the same effect, but the effect is much smaller; Zn, Sb, Ti, V have little or no effect; Mn, Cr, Zr can reduce pitting; Cr Mn can greatly improve the resistance of Al-Mg alloy to intergranular corrosion and stress corrosion cracking; Zr, Mo, Si, Cu, Be, Sb, Zn, etc. also have such a effect, but their effects are roughly decremented according to this order. .

Vitamin A deficiency is occasionally seen in chickens and turkeys (insufficient vitamin A during 1-7 weeks of age). As in the case of other nutritional deficiencies, classic signs of deficiency are very rare in commercial poultry fed complete diets.

Poor growth.
Poor feathering.
Nasal and ocular discharge.
Pale comb and wattles.
Eyelids stuck shut with thick exudate.

Vitamin A in drinking water.


Vitamin E is a fat-soluble vitamin with antioxidant properties.Vitamin E is the most powerful antioxidant vitamin, its prime function is to help scavenge free radicals. … Necessary for the reproductive system, birds before the breeding season supplemented with Vitamin E produce a better fertility.



The deficiency of vitamin E in poultry is manifested in three different forms: encephalomalacia, muscular dystrophy and exudative diathesis. Each of them is usually encountered independently, although sometimes they occur at a time. Encephalomalacia (crazy chick disease). The signs are associated to the central nervous system lesions. They include ataxia, disequilibrium, falling on the back, frequent movements with the wings, strongly stretched legs (clonic spasms) and twisting of the head. Rarely, torticolis or opisthotonus could be observed.

Vitamin D3 is required for proper absorption and utilisation of calcium and phosphorous, which are required for normal growth, bone development, and eggshell formation.



The vitamin D3 deficiency or lack, or the impaired ratio of calcium and phosphorus result in rachitis in young birds. It is encountered more frequently in industrial poultry breeding where the forages are often inadequately balanced. The deficiency of vitamin D3 and phosphorus are more common in growing birds whereas the calcium deficiency in young or adult layer hens. The newly hatched chickens have depleted calcium stores. The calcium deficiency is rapidly manifested if they do not receive an adequate diet supplement. Clinically and morphologically, soft bones or various degree of bone deformation are determined. The birds usually lie down and their growth is retarded. The diagnosis is based upon the complex evaluation of their age, signs and lesions. The supplementation of vitamin D3 with water or forage and the balancing of Ca/P ratio in the diet contribute to the favourable outcome of the disease.
