3ALB260 - Harris ERCuAl-A2 Aluminum Bronze TIG Rod 1/8" - 10 lb Box

Harris ERCuAl-A2 Aluminum Bronze TIG Welding Rod

The Harris ERCuAl-A2 Aluminum Bronze TIG Welding Rod is a premium copper-based alloy designed for high-performance joining and surfacing applications. Engineered to meet strict ANSI/AWS A5.7 and ASME SFA-5.7 standards, this filler metal is essential for industries requiring materials with exceptional mechanical properties and environmental resistance. The A2 alloy composition provides a robust tensile strength of 79,000 psi and a yield strength of 35,000 psi, making it structurally sound for critical components.

One of the defining characteristics of this rod is its outstanding resistance to corrosion and erosion, particularly in saline environments. This makes it the filler metal of choice for fabricating and repairing marine hardware, such as ship propellers, pump housings, and valve seats that are constantly exposed to salt water and acidic conditions. Beyond marine use, it serves as an excellent solution for industrial machinery that requires a bronze wearing surface to mitigate friction and extend component life.

Fabricators rely on the Harris ERCuAl-A2 for its versatility in metallurgy. It is specifically formulated to weld aluminum bronze base metals but is equally effective in joining dissimilar metals. It can successfully bond steels and cast irons to copper, brass, and bronze, providing a ductile and strong interface. This 10 lb box contains 36-inch straight lengths with a 1/8-inch diameter, suitable for standard manual TIG welding setups requiring precise heat control and bead appearance.

Whether used for building up worn shafts or fabricating new corrosion-resistant assemblies, this Harris TIG rod delivers consistent quality and arc stability. It is a vital consumable for maintenance, repair, and overhaul (MRO) operations dealing with copper alloys and complex metal combinations.
