Deformation of Magnesium Alloy
Model：
m002
Features
Details
Deformation of magnesium alloy without ordinary magnesium alloy with good shock absorption and electromagnetic shielding and other functions, and the organization than the casting of magnesium alloy uniform fine, plastic toughness improved, higher than the strength, weight loss better. At the same time, has a good cutting performance and welding performance, to facilitate the subsequent parts of the finished product processing.
