Remarks

Originally developed as a brazing alloy due to its low melting point and high fluidity. This alloy is scarcely susceptible to cracking when used to weld alloys of series 2XXX or aluminium-copper-silicium alloys. It can be used for applications were high temperatures are required. This alloy is usually preferred to the 2319 alloy as it flows better in the weld puddle. The weld bead has a brighter and a more “smut free” appearance with respect to other alloys. It has an ultimate tensile strength lower than alloy 2319. It is not recommended to use this alloy for welding aluminium alloys with a high magnesium content.
