SG CuMn13Al7 GMAW-GTAW Solid wires




SG CuMn13Al7

 
TYPE 
Solid high strenght CuMnAlNi alloyed welding wire.
APPLICATIONS 
Joint welds or building up of aluminum bronze. Cladding components undergoing metal to metal wear under high pressure. Especially suited for marine environments. The addition of manganese and nickel improves hardness and strength. Excellently suitable for joining and cladding of copper alloys, unalloyed and low-alloy steels and grey cast iron
PROPERTIES 

Highest grade of the Al-Bronze-types. Seawater-resistant copper-aluminum alloy without Zn with high toughness and improved hardness.  “Very good weldability compare to the more common Al. bronzes. “
