The application of the aluminum alloy products(2)

Chemical industry of the aluminum alloy products
Aluminum has good thermal conductivity. Aluminum and aluminum alloys are widely used in the production of heat exchange equipment in chemical equipment, storage tanks resistant to concentrated nitric acid corrosion, adsorption filters, fractionators, pipelines and many linings. Cast aluminum alloy has good fluidity, strong mold filling ability, small shrinkage, not easy to form cracks, good corrosion resistance (aluminum oxide and silicon dioxide protective film can be formed on its surface), light weight and good mechanical properties. It is widely used to manufacture corrosion-resistant parts with complex structure, such as cylinders, pipe fittings, valves, pumps, pistons, etc. Aluminum has many special uses in chemical production. Aluminum does not produce sparks, and aluminum alloy can produce containers containing easily volatile substances; Aluminum is non-toxic, will not cause food deterioration, will not affect the appearance of goods and will not corrode goods. Therefore, aluminum alloy is widely used to make relevant equipment in food chemical industry.

Metal packaging of the aluminum alloy products
Aluminum alloy can be used for metal packaging, which has the following excellent characteristics: good mechanical properties, light weight, high compressive strength, durability, easy to store and transport goods; Good barrier performance, can block the damage of sunlight, oxygen and humid environment to articles, and can prolong the shelf life of articles; Good texture and aesthetic feeling. Aluminum alloy is used as packaging, with unique metallic luster, good touch feeling and beauty, so as to improve the quality of goods; Non toxic, easy to recycle, recyclable, saving resources and reducing environmental pollution. Aluminum alloy is widely used in beer, beverage and other food cans, mostly in stamping and drawing structure. Aluminum foil utensils are beautiful, light and good heat transfer. They are used in the packaging of fast food. They have the effects of fresh preservation, taste preservation and non-toxic. They are used by more and more food industries. The aluminum alloy metal hose can be extruded and deformed, and the contents can be used after extrusion. It is simple and convenient. It is commonly used in the packaging of paste cosmetics.

Other industries of the aluminum alloy products
Aluminum alloy has high specific strength, light weight, good fluidity, strong filling capacity, good corrosion resistance and low melting point. It is widely used in tractor, locomotive parts, electronic products, medical devices, building decoration and other industries. Aluminum alloy has excellent ductility and is widely used in daily necessities industry and food industry. In the field of power transmission, aluminum alloy conductor has attracted more and more attention because of its low cost, light weight, good corrosion resistance, heat transfer, easy conductivity and wear resistance. In the field of power transmission, aluminum alloy is used the most, and up to 90% of the high-voltage conductor materials are aluminum products. Al Si alloy can be used as a good deoxidizer to reduce the sensitivity of steel to subcutaneous bubbles, deoxidize steel and improve the quality of steel. The market consumption of Al Si alloy is large, and the national annual demand is up to one million tons.
