The specificity of aluminum alloys

1. Low density

The density of aluminum is about one-third of that of copper (8.9) or steel (7.8). Low density is very beneficial for spacecraft, ships, vehicles and other means of transport and building light weighting, but also can save moving costs and processing costs, reduce costs, in industry, construction and other fields of civil use more widely.

2. Good corrosion resistance, weather resistance

Aluminum and aluminum alloy in the atmosphere can form a layer of hard and dense, with good corrosion resistance of the oxidation film, through anode oxidation, electrophoresis painting, powder spraying and other surface treatment, can further improve the corrosion resistance of aluminum

3. Good decoration

Aluminum alloy has good plasticity, can process a variety of specifications, the formation of products, through surface treatment can produce different properties, different colors of the film layer, with good decorative.

4. Good thermal conductivity

Aluminum has a high thermal conductivity, second only to silver, gold and copper in metals, is three times that of iron, and the same weight of aluminum is 12 times that of iron, so aluminum alloy is a good material for the manufacture of radiators and heaters.

5. Easy to process

Aluminum alloy density is low, but the strength is relatively high, close to or more than high-quality steel, plasticity is good, add certain alloy elements, can obtain good casting properties of cast aluminum alloy or processing plasticity of aluminum alloy.
