Alloy 150 Zirconium Copper

Sequoia Brass and Copper sells alloy 150 zirconium copper. A small addition of Zr to copper improves resistance to softening and resists deformation at high temperatures where normal copper would soften rapidly. Zirconium copper is used as a Class 1 electrode material to minimize sticking when resistance spot welding galvanized materials. Common fabrication processes for 150 zirconium copper include bending, hot forging, machining, heading, and swaging. 150 zirconium copper comes in rod and wire forms. Typical uses of 150 zirconium copper are consumer, electrical, and industrial products.
