Magnesium Alloy Plate AZ31B AZ91D For Notebook Brain Phone Case Car Industry

Magnesium alloy parts have high stability. Die casting parts have high dimensional accuracy in the casting line and can be processed with high precision.
Magnesium alloy has good die-casting forming performance, and the wall thickness of die-casting parts can be as small as 0.5mm. It is suitable for manufacturing all kinds of die-casting parts of automobiles.
However, the coefficient of linear expansion of magnesium alloy is very large, reaching 25~26 μm/m℃, while that of aluminum alloy is 23 μm/m℃, brass is about 20 μm/m℃, structural steel is 12 μm/m℃, and cast iron is about 10 μm/m. m℃, rock (granite, marble, etc.) is only 5-9 μm/m℃, and glass is 5-11 μm/m℃.
