Press works by Magnesium Alloy
Press works by Magnesium Alloy
For realization of a low carbon society, to utilize the magnesium alloy which has the lightest weight in the all commonly metals and the weight-to-strength ratio is indispensable. It is necessary to produce press works having a complicated three-dimensional figure with high productivity press machine for general use.
Magnesium alloy sheet AZ61 manufactured by Gonda Metal is excellent in the weight-to-strength ratio, good at the surface treatment like plating and workability.
Excellent merits in the press works made of AZ61
Deep drawability is equal to AZ31
Excellent in surface treatment and both plating and coating can be performed
LDR of AZ61 shows 1.4 at room temperature and over 2.0 at 250 ℃
