1.low melting point, good fluidity 2.Used for aluminum brazing of electric machine, appliance, refrigerator.
As one of the most common aluminum welding materials,ER4043 and ER4047 are often used for brazing 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
