CuAl8Ni2 Tig

type 
Tig Aluminium / Nickel alloyed copper 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 nickel improves corrosion resistance in heat and rough seawater.
Properties 

•       Special alloyed copper wire for the Tig process
•       The weld metal is a Cu-Al-Ni bronze
•       Sound, pore free deposits on ferrous and non-ferrous base materials
•       Excellent resistance to cavitations and stress corrosion cracking.
