4047 Aluminium Alloy Powder
【Application】
① Brazing: eutectic brazing filler metal has good brazing property and brazing strength, excellent plating and corrosion resistance, and the color is consistent with that of the base metal;
② Spraying: it is used for wear or out of tolerance repair of aluminum base alloy and magnesium alloy parts. It can be remelted after spraying and has certain self fusibility;
③ 3D printing: eutectic composition, good melt fluidity during high temperature forming;
④ Porous material: used as filter material, it has the advantages of high specific strength and low cost compared with stainless steel and high-temperature alloy
