进口瑞典伊萨OK AutrodCuSi3/ERCuSi-A硅青铜合金焊丝12.5公斤/盘

　　ESAB OK Autrod 19.30 is a solid copper wire for the GMAW joining of copper-zinc alloys and low-alloyed copper and for the GMAW brazing of zinc-coated steel sheets.It is alloyed with silicon and manganese and has good flow properties and wear resistance. This alloy is widely used in the joining of zinc-coated steel sheets in car body production, as well as for overlay welding on low- and non-alloyed steels and cast iron. Pulsed or specialised GMAW is recommended.This wire is normally welded with pure Ar as the shielding gas,however,forGMAW brazing the addition of 1% O2 improves the brazing properties.
