ER CuSn1

BLUWELD
ERCuSn1

Tin alloyed copper wire electrode for GMA (MIG) welding of copper and low alloyed copper alloys. Particularly used in electric and heat conductor parts, which are made of pure copper. Suitable for welding oxygen-free copper and copper materials subject to high strain. Gives pore-free and easily machinable welding seams.
