ERCuAl-A1 (Alum Bronze A1)

< CLICK HERE for additional information on this alloy >

 

 

ERCuAl-A1 Aluminum Bronze is an iron-free aluminum bronze filler metal used for MIG and TIG overlaying.  It is not recommended to be used for joining.  Because of its moderate strength it is predominantly used for weld overlay and metalizing in automotive and other manufacturing operations.  It can also be used for build-up and repair of bearing and corrosion resistant surfaces.

 

Typical Applications:  overlaying of wear resistant surfaces subject to corrosive environment, overlaying of tube sheets, refineries, and valve seats in pulp mill
