SAE AMS4189H

This specification covers an aluminum alloy in the form of welding wire.

This wire has been used typically as filler metal for gas-metal-arc or gas-tungsten-arc welding of heavy sections of aluminum alloys of similar composition to produce joints having inherently low dilution ratio of base-metal to weld-metal, and where the weldment may require solution and/or precipitation heat treatment, but usage is not limited to such applications.
