ADC12 is a Japanese aluminum alloy, also known as No. 12 aluminum material, Al-Si-Cu alloy, is a die-cast aluminum alloy, suitable for cylinder head cover, sensor bracket, cover, cylinder block, LED lamp cooling, automotive parts casting, etc. The Chinese standard is JIS H 5302-2000
Chemical composition
Si 9.6～12
Fe<1.3 (When the content is lower than 0.6, the mold sticking is more serious in die casting, and the specific composition will be determined according to the relevant needs of customers)
Cu 1.5 ~ 3.5 (usually 1.6 is enough)
Mg<0.3
Mn<0.5
Zn<1.0
Ni<0.5
Sn 0.2 or less (YL113 0.1 or less)
Pb 0.2 or less
Si 9.6 to 12
Fe<Below 0.9 (the iron content of ADC12 made with primary aluminum is about 0.6)
Cu 1.5 ~ 3.5 (usually 1.6 is enough)
Mg<0.3
Mn<0.5
Zn<1.0 (The zinc content of ADC12 made with primary aluminum is about 0.3)
Ni<0.5
Sn 0.2 or less (YL113 0.1 or less)
Pb≤0.05 (low lead, food grade can be achieved)
