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 aluminum alloys of similar composition, but usage is not limited to such applications.
Rationale: AMS4190J restores this document to active status because AWS A5.10, ER4043. does not have alloy verification requirements to the packaging level, and revises Table 1 to reflect the registered alloy composition.
Also known as: SAE AMS 4190
