Properties Of Aluminum Alloy

Compared with other metal materials, aluminum alloy has the following characteristics: 1, small density: the density of aluminum alloy is close to 2.7 grams/cubic centimeter, about 1/3 of copper. 2, high strength: high strength of aluminum alloy. After a certain degree of cold processing can strengthen the matrix strength, some grades of aluminum alloy can also be strengthened by heat treatment. 3, good electrical and thermal conductivity: aluminum's electrical and thermal conductivity is second only to silver, copper and gold. 4. Good corrosion resistance: the surface of aluminum is easy to naturally produce a layer of dense and firm AL2O3 protective film, which can protect the matrix from corrosion. By artificial anodic oxidation and coloring, casting aluminum alloy with good casting performance or deformation aluminum alloy with good processing plasticity can be obtained. 5, easy processing: after adding a certain alloying element, can obtain good casting performance of casting aluminum alloy or good plastic deformation aluminum alloy processing.
