Aluminium chair armrest is one of die-casting series of Kinnay aluminium products. Its main usage is as aluminium office chair armrest. In order to stabilize our quality, aluminium alloy-ADC12 is our first choice material in production. ADC12 is a die-cast aluminum alloy, suitable for cylinder head covers, sensor brackets, cylinder blocks, etc., the implementation standard is: JIS H 532-2006 "Aluminum Alloy die castings". It is also popular in producing furniture accessories now. ADC12 is equivalent to China's domestic alloy code YL113, alloy brand is YZAlSi11Cu3, the implementation of GB/T 15115-2009. The American alloy grade is 384, and the implementation standard is ASTM B 85-03 Standard Specification for Aluminum-Alloy Die Castings (there may be a newer version than ASTM B 85-03).

ADC12 aluminum (Al) allowance, copper (Cu) 1.5 ~ 3.5, silicon (Si) 9.6 ~ 12.0, magnesium (Mg) of 0.3 or less, zinc (zinc) 1.0 or less, iron (Fe) of 1.3 or less, manganese (Mn) of 0.5 or less, nickel (Ni) of 0.5 or less, tin (Sn) of 0.2 or less, calcium (Ca) ≤200ppm, lead (Pb) ≤0.1, cadmium (Cd) ≤0.005.

ADC12 is a better material than ordinary aluminum alloy. In the process of die casting, the semi-finished product after die casting will have a better filling feeling, and the surface will be smoother. It is also easier to handle sharp edges after die-casting. In terms of polishing, the product will be more convenient for processing, so the product will have a better luster after polishing, but also improve the yield of the product. This is also why our aluminium chair armrest could be recognized by our customers. If you are planning to look for suppliers of aluminium office chair armrests.
