CuAl8Ni6 Tig GMAW-GTAW Solid wires




CuAl8Ni6 Tig

 
TYPE 
Copper Aluminium Nickel alloy for GTAW welding (Tig)
APPLICATIONS 
Desalting installations, CuNiAl ship propellers, cladding against corrosion, cladding against wear, gliding surfaces, shipbuilding, pump building, shafts, guide grooves, tube systems etc.
PROPERTIES 

• The weld metal is a Cu-Al-Ni bronze

• Sound, pore free deposits on ferrous and non-ferrous base materials

• Seawater, wear and corrosion resistance; for example when seawater, cavitation and erosion are simultaneously affecting the weld deposit.

CLASSIFICATION
AWS 
A 5.7: ER CuNiAl
EN ISO 
14640: S Cu 6328 (CuAl9Ni5Fe3Mn2)
DIN: W.Nr. 
2.0923
DIN 
1733T.1: SG CuAl8Ni6
SUITABLE FOR 

CuNiAl, CuAlNi, aluminium bronze, ship propellers, 2.0923, Joint welds or building up of aluminum bronze. Cladding (steel) components undergoing metal to metal wear under high pressure. Especially suited for marine environments. The addition of nickel improves corrosion resistance in heated and rough seawater.
