Copper Welding Wire
Product Details
Our ERCuSn-C phosphor bronze Welding Wire is a tough, reliable choice for heavy-duty machinery joints. With about 7% tin and a copper base, this wire delivers strong, wear-resistant welds that can handle the toughest conditions. Designed for TIG and MIG welding, it offers a stable arc, low spatter, and smooth bead appearance. It’s perfect for joining bronze, brass, or copper components and for surfacing parts that face heavy wear, like gears or bearings. This wire is built to keep machinery running strong, no matter the load.
We’ve engineered our ERCuSn-C wire to shine in demanding applications. The high tin content boosts weld strength and wear resistance, with tensile strength around 50,000-60,000 psi, making it ideal for heavy machinery. It’s also corrosion-resistant, holding up well in moist or mildly acidic environments, which is great for industrial settings. The wire’s smooth flow ensures clean welds with minimal cleanup, whether you’re repairing a worn shaft or building a new component. It’s versatile, durable, and easy to work with for both manual and automated setups.
The copper-based welding wire market is on an upward swing, expected to hit USD 4.5 billion by 2030 with a 5.5% CAGR. Heavy industries like manufacturing, mining, and construction are driving demand for durable, wear-resistant materials. Phosphor bronze wires like ERCuSn-C are prized for their strength and ability to extend the life of machinery components. As automation and heavy equipment production grow, the need for reliable welding solutions that can handle high stress and wear is bigger than ever, and our wire is up to the challenge.
Our ERCuSn-C wire is a workhorse for heavy machinery welding. It’s used for joining bronze and brass components in construction equipment, mining machinery, and industrial gears. The wire’s wear resistance makes it perfect for surfacing parts like bearings, bushings, and propeller shafts that face constant friction. It’s also great for repairing worn machinery, extending service life and cutting downtime. In marine and industrial settings, its corrosion resistance ensures welds stay strong even in tough, wet conditions.
