ERCuSi-A (Silicon Bronze)

< CLICK HERE for additional information on this alloy >

 

ERCuSi-A  Silicon Bronze is primarily used for MIG, TIG and gas welding of copper, copper-silicon and copper-zinc base metals to themselves and to steel.  It is an excellent choice for joining plain or galvanized sheet steel to metal as well as other coated steels.

 

Typical Applications: surfacing areas subject to erosion
