ER 4043 – AMS 4190 – Aluminum Welding Wire

Specifications:
AWS Class ER 4043
AWS A5.10,
ASME SFA 5.10
AMS 4190
UNS A94043

Description: 
Aerospace Material Specification 4190 is aluminum alloy 4043 in welding wire form. Typically used as a filler metal for gas-metal-arc or gas-tungsten-arc welding applications of similar composition. ER4043 is used to weld heat treatable alloys. It has a lower melting point and more fluidity than the 5000 series aluminum. Typical applications include bicycles, trucks, trailers, and automotive parts and equipment.

Aluminum 4043 is a general purpose filler metal with a principle element of silicon.
