Aerospace Material Specification 4191, alloy 2319, is aluminum alloy 2319. The specification covers filler metal for us in gas-metal-arc or gas-tungsten-arc welding of aluminum alloys in similar composition.

Alloy 2319 is commonly used in high strength structural and aircraft applications. This alloy is typically used when greater resistance to stress corrosion cracking is desired.

Available in multiple diameters and sizes in straight length wire and in spools.
