ADC12 is a Japanese grade, also known as No. 12 aluminum, Al-Si-Cu system alloy, is a die-casting aluminum alloy, suitable for cylinder head cover, sensor bracket, cylinder block class, etc., the implementation standard is: JIS H 5302-2006 "aluminum alloy die casting".
ADC12 is equivalent to China's domestic alloy code YL113, the alloy grade is YZAlSi11Cu3, the implementation standard GB/T 15115-2009, the United States alloy grade is 384, the implementation standard: ASTM B 85-03 Standard Specification for Aluminum- Alloy Die Castings

ADC= Aluminum-Alloy Die Castings
Japanese aluminum alloy grade, also known as No. 12 aluminum material, Al-Si-Cu system alloy, is a die-casting aluminum alloy, suitable for cylinder head cover, sensor bracket, cover, cylinder block class, etc., the implementation of the standard: JIS H 5302-2000 "aluminum alloy die castings".

Japan's ADC10 and ADC12, basically is recycled with scrap aluminum, Japan also developed the standard of scrap aluminum recycled die-casting aluminum alloy. At present, the domestic widely used die-casting alloy Y112, according to the Ministry of Machinery Industry's die-casting alloy standards, it is more suitable to use scrap aluminum to melt, which can undoubtedly alleviate the contradiction between the supply and demand of aluminum ingots.
Composition
ADC12 contains aluminum (Al) balance, copper (Cu) 1.5 ~ 3.5, silicon (Si) 9.6 ~ 12.0, magnesium (Mg) ≤ 0.3, zinc (Zn) ≤ 1.0, iron (Fe) ≤ 1.3, manganese (Mn) ≤ 0.5, nickel (Ni) ≤ 0.5, tin (Sn) ≤ 0.2, calcium (Ca) ≤ 200ppm, lead (Pb) ≤ 0.1, cadmium ( Cd) ≤0.005
