Introduction

C87200 Copper Metal Strips

C87200 is a cast silicon brass alloy known for its excellent castability, which allows it to fill intricate mold cavities and form complex-shaped components such as valve bodies, pump parts, and pipe fittings. It offers a balanced combination of mechanical strength and good electrical and thermal conductivity, making it suitable for both structural and functional applications in industrial environments.

In addition to its processing advantages, C87200 copper strip exhibits good corrosion resistance, particularly against fresh water, steam, and various chemical media. This durability extends the service life of components used in plumbing systems, marine equipment, and low-to-medium pressure fluid handling applications. Its reliable performance under moderate mechanical stress and corrosive conditions makes it a practical choice for cast copper alloy parts.

Applications for C87200 Copper Metal Strips

Valve components

C87200 copper strip is widely used to manufacture valve bodies, bonnets, and discs for industrial plumbing, water supply systems, and low-to-medium pressure fluid control applications due to its good castability and corrosion resistance.

Pipe fittings and flanges

The alloy is commonly cast into elbows, tees, couplings, and flanges for piping systems, especially where resistance to dezincification and sealing reliability are required in water or steam service.

Pump parts

Components such as pump housings, impellers, and wear rings benefit from C87200's combination of mechanical strength, castability, and resistance to erosion and corrosion in aqueous environments.

General industrial hardware

It is also applied in the production of various cast hardware items, including bearing retainers, gear blanks, and valve stems, where moderate strength, good machinability (when cast), and corrosion resistance are needed.
