Introduction

C87400 Solid Copper Bar

C87400 copper rod is a lead-free, eco-friendly brass alloy primarily composed of copper, silicon, and zinc. It is widely used in plumbing components, valve stems, and hardware fittings due to its compliance with modern environmental standards for drinking water systems. Its silicon-enhanced composition provides excellent castability and pressure tightness, making it a reliable choice for complex-shaped parts.

In addition to its environmental benefits, C87400 offers good machinability and outstanding corrosion resistance against fresh water, seawater, and various atmospheres. These properties ensure long service life and stable performance in demanding applications. The alloy also exhibits moderate strength and good thermal conductivity, further expanding its utility in fluid handling and mechanical systems.
