C87200 is a cast copper alloy belonging to the silicon bronze family, valued for its combination of strength, corrosion resistance, and casting fluidity. As a copper plate, it offers moderate to high mechanical strength while maintaining good ductility, making it suitable for components that require both durability and formability. Its silicon content enhances oxidation resistance and improves the material’s performance in elevated-temperature service environments.
In addition to its mechanical and thermal properties, C87200 copper plate exhibits excellent resistance to corrosion in marine, industrial, and mildly acidic atmospheres. This makes it a preferred choice for valve bodies, pump components, pipe fittings, and other fluid-handling equipment. The alloy also casts readily into complex shapes with good pressure tightness, further expanding its utility in demanding engineering applications.
