OVERVIEW

Premium Phosphor Bronze MIG Wire for Industrial Applications

The Böhler Welding ERCuSn-A MIG Wire is a high-grade copper-tin alloy designed for professional welding operations requiring superior strength and corrosion resistance. Commonly referred to as Phosphor Bronze A, this .045-inch diameter wire is engineered to meet the rigorous demands of joining copper base metals, specifically tin-bronzes, and is exceptionally effective for surfacing applications on steel and cast iron. The addition of tin (approximately 5-6%) increases the wear resistance of the weld deposit, making it an excellent choice for building up bearing surfaces and other components subject to friction.

Packaged in a substantial 15kg S300 wire basket, this product is tailored for high-volume industrial environments. The S300 spool ensures compatibility with most standard industrial wire feeders, providing a smooth and consistent wire payout that minimizes downtime caused by tangling or feed interruptions. Böhler Welding is renowned for its metallurgical expertise, and this wire reflects that legacy with a clean surface finish and consistent chemical composition, ensuring reliable arc characteristics and defect-free welds.

One of the standout features of the ERCuSn-A alloy is its versatility in joining dissimilar metals. It is frequently used to weld copper or bronze to steel, a common requirement in artistic fabrication, marine repair, and heavy equipment maintenance. The deposit offers excellent resistance to seawater corrosion and industrial chemical environments. When used with 100% Argon or an Argon/Helium mixture, welders can achieve a clean, aesthetically pleasing bead with minimal spatter. Whether you are repairing marine propellers, fabricating bronze sculptures, or overlaying shafts, the Böhler ERCuSn-A provides the mechanical properties and ease of use necessary for high-quality results.

Key Applications

  • Joining copper and copper-tin bronzes
  • Surfacing and overlay on steel and cast iron
  • Repairing bearing surfaces and guides
  • Welding dissimilar metals (Copper/Bronze to Steel)
  • Marine component fabrication and repair

FAQ

This wire is classified as ERCuSn-A according to AWS A5.7 standards.

100% Argon is typically recommended for thinner sections. For thicker base metals, an Argon/Helium mixture can be used to increase heat input and flow.

It is not used to join steel to steel, but it is excellent for surfacing (overlaying) steel or for joining copper/bronze alloys to steel.

This product comes in a 15kg (approx. 33lb) package on an S300 wire basket spool, which fits standard industrial wire feeders.

No, this is Phosphor Bronze (Copper-Tin). Silicon Bronze (ERCuSi-A) is a different alloy. Phosphor bronze is often preferred for color matching certain bronzes and for specific wear applications.

The wire diameter is 0.045 inches (approximately 1.2mm).

DCEP (Direct Current Electrode Positive) is the standard polarity for MIG welding with this wire.
