Arc Welding Service

CATEGORY

TYPE

Copper-Silicon filler metal for Laser brazing.

APPLICATIONS

Brazing thin plates and or galvanized plates in the car industry and also for cladding CuMn, CuSiMn and CuZn alloys. Suitable for cladding cast iron and un- and low alloyed steels. Examples: Automobile industry, art work, cladding on steel, cast iron and copper alloys etc.

PROPERTIES

•       High quality alloyed copper wire designed for laser welding and brazing
•       The deposit is a Copper- Silicon bronze
•       Sound, pore free deposits on ferrous and non-ferrous base materials
•       Excellent corrosion resistance.
