G-TECH CuSn7
SMAW
- COPPER ALLOYS
CuSn
Description
Electrode with special basic coating
It's particularly suitable for welding and recharging
of phosphorous bronze or similar, brass and for recharging cast iron and carbon steel.
It is used for the construction of pump blades, turbines, parts subject to wear, such as sliding guides, sliders, seats of
valves, for repairing foundry and plating defects on tough steel
to sea water. The higher tin content increases strength and wear resistance and increases the solidification temperature range during deposition of the weld metal (lower preheating to about 200°C is required).
