1.Welding filler.
2.Metal spraying.
3.Similar to AlSi12 (Germany), BS N21 (United Kingdom).
4.Lower melting point and higher fluidity than 4043 wires.
5.Widely used for brazing of aluminum, Al-Mn, Al-Si-Mg alloy materials.
6.Can be used as a substitute for 4043 wires to increase silicon in the weld metal, minimize hot cracking and produce higher fillet weld shear strength.
