Key Features

Welding
Metal
Similarto AlSi12 (Germany), BS N21 (United Kingdom).
Lowermelting point and higher fluidity than 4043
Widelyused for brazing of aluminum, Al-Mn, Al-Si-Mg alloy
Canbe used as a substitute for 4043 wires to increase silicon in the weld metal, minimize hot cracking and produce higher fillet weld shear

Application

Automotivecomponents
Bodypanels
Brazingof aluminum sheets, extrusions, and castings

Shielding Gas

100%Argon or Argon/Helium mixture
