4043 aluminium braze welding foil

Introduction of 4043 aluminium braze welding foil
4043 aluminium braze welding foil can be used to make welding wire, has a lower melting point than aluminum-magnesium alloy, better fluidity and corrosion resistance, and the welding crack tendency is much lower than that of aluminum-magnesium alloy welding wire, widely used in 6XXX marine Welding of aluminum alloy parts.
