YL 1 12 is a die-casting aluminum alloy material, and its main elements are Si: 7.5 ~ 9.5%, Cu: 3.0 ~ 4.0%, Mn: ≤ 0.50%, Mg: ≤ 0. 10%, and Fe: ≤ 0./.

Its price is generally on the basis of A00 spot price plus 1000~2500 yuan processing fee. Processing costs are related to the prices of metals such as copper and silicon and the cost of fuel.
