YL302
USA 712 is similar with ISO AlZnMg ac71000 .it has bad castability
1. Fluidity
ability of an alloy to make thin wall castings and reproduce fine detail
2. Hot tearing
tendency for a crack to form in a casting due to the development of internal stress during solidification 3. Pressure tightness
tendancy not to leak during pressure testing
4. AlSi10Mg 的可压铸性能很差，不推荐使用
