AWS Class ER 4043
ASME SFA 5.10
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.
