| Standard title | Magnesium alloy die castings |
| Objective |
This standard specifies magnesium alloy die-castings， but revisions are being made to enhance the content of the standard in light of recent trends in production and use. The main revisions are as follows: - In terms of type and type symbols， new symbols will be established in line with market conditions in Japan， and four new types of magnesium alloy die-castings will be added. - 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 heat sink parts. - High heat-resistant， flame-retardant alloy. For drive system parts such as automobile transmissions. - In terms of chemical composition， in line with the addition of alloy types， the chemical compositions of new alloy types will be added in line with market conditions in Japan. - In terms of mechanical properties， in line with the addition of alloy types， the mechanical properties of new alloy types will be added in line with market conditions in Japan. |
