Copper-Silicon MIG Wire

Value Brand ERCuSi-A wire is a copper-based filler metal supplied on an 11 lb plastic spool. It is formulated for MIG welding of dissimilar metals including brass, bronze, copper and cast iron to steel. The wire diameter is .03 in and carries an AWS ERCuSi-A classification.

Suited for dissimilar-metal repairs

Technicians joining copper alloys to ferrous parts will find the silicon-bearing chemistry matches the required mechanical properties. The spool feeds through standard MIG guns using AC or DCEP polarity. Shops that exclusively weld mild steel, stainless steel or aluminium should select a different filler wire.

Tensile strength 50 ksi

The as-welded deposit delivers 50 ksi tensile strength, the key figure for judging whether the joint meets design requirements. Yield strength is not rated by the manufacturer, so engineers must verify suitability against their specific code or drawing.

Questions about this item

Will the 11 lb ERCuSi-A spool feed reliably through my older MIG gun and drive rolls sized for .030 wire?

The wire diameter is .030 in, matching standard drive rolls and liner sizes for that gauge, so it feeds through existing MIG guns set up for .030 without modification.

How can I confirm the welds meet the 50 ksi tensile strength after I finish a joint?

A properly set MIG weld using ERCuSi-A on listed base metals should achieve 50 ksi as-welded tensile strength; verify with a bend test or send a sample for tensile testing if certification is required.

Does the 11 lb plastic spool come with any contact tips, liners or shielding gas, or must I buy those separately?

The package contains only the 11 lb ERCuSi-A wire on a plastic spool; contact tips, liners and shielding gas are sold separately.
