Characteristics of aluminum alloy

The commonly used antirust aluminum alloy is characterized by corrosion resistance, good polishing, can maintain a bright surface for a long time, and its strength is higher than that of pure aluminum. It is mostly used to manufacture parts, pipes, daily necessities, decorations, etc. in contact with liquid; Duralumin is an alloy of aluminum, copper and magnesium, and contains a small amount of manganese; Duralumin can manufacture rivets, aircraft propellers and high-strength parts on aircraft according to its different alloy element content; Superhard aluminum is hard aluminum containing zinc. Its hardness and strength are higher than that of hard aluminum. It is used to manufacture various structural parts and high load parts. It is one of the important materials in the aviation industry; Forged aluminum has high plasticity and high strength in general state. It is used to manufacture all kinds of forgings or stamping parts, such as internal combustion engine piston, etc;Cast aluminum alloy is an aluminum alloy material used to directly cast various shapes of mechanical parts.

Aluminum and aluminum alloys are more and more widely used in the shipbuilding industry, ranging from motor boats to 10000 ton oil tankers, from offshore hovercraft to submarine, from civil to military, from fishing ships to marine mining ships. Aluminum alloys with excellent comprehensive performance are used to produce ship shells, support structures, supporting facilities, pipelines, etc. Aluminum alloys used in marine industry are mainly aluminum copper alloy, aluminum magnesium alloy and aluminum silicon alloy. Aluminum magnesium alloy is mainly used for hull shell, water pump conduit, pump shell and base support, with grades of 5083, 5086, 5456, 5466, etc. Aluminum silicon alloy has moderate structural strength, good fluidity and strong filling capacity. It is easy to produce parts with high density and complex structure, such as high-pressure valve, cylinder block, pump, reducer housing, turbine blade, etc.

Aluminum has good thermal conductivity, so aluminum and aluminum alloys are also 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 capacity, small shrinkage, not easy to form cracks, good corrosion resistance, 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 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 also widely used to make relevant equipment in food chemical industry. Aluminum alloy is also widely used in beer, beverage and other food cans. Most of them are stamping and drawing structures. 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.

Aluminum alloy has high 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.
