Al-Si alloy welding wire ER4043 

 JIS A4043 
 Description: 311 is a versatile large Al-Si alloy wire, weld metal has excellent resistance to thermal cracking performance, but also to guarantee the mechanical properties. But anodized occasions during the weld metal and base metal different colors of gold while welding aluminum and magnesium generated in the weld brittle Mg2Si, the joint ductility and corrosion resistance decreased. 
 Use: commonly used in addition to aluminum-magnesium alloy of gold artifacts and castings other than welding and oxygen - acetylene welding filler material when, in particular, is easy to produce thermal cracks on the heat treatment to strengthen aluminum alloys, can obtain good results. 



 HS321 Al-Mn alloy wire 
 Note: 311 is aluminum manganese alloy wire, weld metal has good corrosion resistance and high strength than pure aluminum, weldability and ductility is also very good. 
 Uses: Suitable for aluminum and other aluminum welding manganese and oxygen - acetylene welding time as a filler material.
