Among a wide range of cast aluminum alloys, which is the best for your die casting parts? Outstanding characteristics make aluminum commonly used in the metal casting industry, at DIECASTING-MOULD, today we’ll look into another aluminum alloy – A360, with its composition, properties, and comparison between A360 and 6061-T6.
A360, which is designated by Aluminum Association, is an aluminum alloy used for die casting, in different standards, it is also known as A13600 (UNS number), 309 (SAE), LM9 (British Standard) and A-S10G (AFNOR). A360 aluminum has good fluidity, high strength, high corrosion resistance, and excellent pressure tightness.
A360 Aluminum Chemical Composition
Compared with other die-casting aluminum alloys, A360 cast aluminum contains a high content of silicon and tin, Sn can increase its bearing properties.
– Al: 85.8 – 90.6%
– Si: 9.0 – 10%
– Fe: 0 – 1.3%
– Mg: 0.4 – 0.6%
– Cu: 0 – 0.6%
– Ni: 0 – 0.5 %
– Zn: 0 – 0.5%
– Mn: 0 – 0.35%
– Sn: 0 – 0.15%
– Residuals: 0 – 0.25%
A360 Aluminum Properties
