AMS4189H - Aluminum Alloy Welding Wire, 4.1Si -0.20 Mg (4643)

Document Number: AMS4189H
Revision Number: H
Aluminum Alloy Welding Wire, 4.1Si -0.20 Mg (4643)
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.
