Al Mg Si series (6XXX Series) aluminum alloy is the only alloy without stress corrosion cracking (SCC) in heat treatment strengthened aluminum alloy. It is most widely used in the automotive field because of its good strength, formability and corrosion resistance. By adding a certain amount of Cu to 6013 alloy, al2cu is introduced on the basis of Mg2Si as the main strengthening phase, which improves the tensile strength [3 ~ 5] and expands the application range of the alloy.
6013 aluminum plate bar has the advantages of high strength, good thermal conductivity, good machinability and chemical polishing effect. It is an ideal material for manufacturing appearance structural parts of electronic products. It is widely used in consumer electronics shells, such as notebook computers, mobile phones, televisions, etc. Among them, 6013 aluminum alloy is one of the most advanced aluminum alloys in the world. Compared with 6061-T6 alloy, the strength of 6013-t6 aluminum alloy is about 25% higher, even comparable to 7 ××× Strength of aluminum alloy. In addition,
6013 aluminum plate bar also has better drilling performance and easy chip removal. It can be used to drill more complex parts and significantly reduce the drilling cost. Therefore, 6013 alloy is regarded as a new generation of ideal material to meet the further needs of the electronic product appearance structure market for high strength, lightweight and easy processing.
(1) Extrusion temperature and extrusion speed have significant effects on the microstructure and mechanical properties of 6013 alloy. The higher the extrusion temperature and extrusion speed, the more conducive to obtain recrystallized microstructure. At low speed, the tensile strength reaches the maximum at extrusion temperature of 500 ℃, while at high speed, the tensile strength reaches the minimum at 500 ℃ due to temperature rise effect and recrystallization.
(2) When the extrusion speed is the same, the hardness of 6013 alloy decreases with the increase of extrusion temperature; The elongation also decreased with the increase of extrusion temperature at speeds of 4 and 6m / min.
(3) The dimple size of tensile fracture of 6013 alloy at room temperature decreases with the increase of temperature, and reaches the minimum at 525 ℃. Reducing the temperature can be used to improve the plasticity of the alloy.
6013 aluminum plate bar produced by Chalco aluminum is widely used in smart phones, tablet computers, smart homes, electronic appliances and other product accessories. It is easy to process and has good color after anodizing.
