ER4047 Aluminum brazing rod 

As one of the most common aluminum welding materials, ER4047 are often used for soldering and brazing of casting aluminum, 

and extrusion molding of aluminum and aluminum alloys with aluminum welding flux.

Advantage:          

1. low melting temperature.

2.good  fluidity

3. little deformation for parent material
