magnesium Alloy Welding Wire

Magnesium alloy welding wire is use in all kinds of forging Mg alloy and cast Mg alloy, such as optical instrument, aerospace, automobile spare parts, magnesium products for civil use, and handiwork welding.

 

The advantages of magnesium alloy welding wire are as follows:

1.      Small  density, lighter than Al, higher specific strength;

2.      Subsititute for engineering plastics;

3.      Higher fatigue limit;

4.      Bigger impact load than Al;

5.      Better thermal conductivity;

6.      Good casting property;

7.      Dimensionally stable;

8.      Easy revocery and high corrosion resistance.

 

The magnesium alloy welding wire follow the standard of GB/T 5153.
