| Standard title | Magnesium alloy ingots for die castings |
| Objective |
This standard specifies magnesium alloy die-casting， but revisions are being made to enhance the content of the standard in light of recent production and usage trends. The main revisions are as follows: - For type and type symbols， new symbols will be established in line with market conditions in Japan， and four new types of magnesium alloy ingots for die-casting will be added， as follows: - High heat-resistant， high thermal conductivity， and flame-retardant alloy. For automobile and motorcycle parts. - High toughness， flame-retardant alloy. For automobile wheels. - High thermal conductivity， flame-retardant alloy. For automobile parts. - High heat-resistant， flame-retardant alloy. For automobile engine parts. - For chemical composition， in conjunction with the addition of alloy types， the chemical compositions of new alloy types will be added in line with market conditions in Japan. |
