Silicon Bronze C87850

Lead-Free Eco-Brass Castings for Potable Water & Marine Applications

Silicon bronze alloy C87850, or eco-brass, is a lead-free silicon alloy developed to help replace traditional leaded bronze and brass materials in any application where potable water compliance, corrosion resistance, and environmental responsibility are critical. It offers a unique combination of strength, casting characteristics, and strong machinability, making it an ideal casting material to produce valves, fittings, pump components, marine hardware, and industrial equipment.

Erie Bronze & Aluminum produces custom C87850 eco-brass sand castings for OEMs requiring high-quality non-ferrous castings with complex geometries, near-net-shape production, and volumes that range from short-run prototyping projects through large-volume production runs.

Why Choose Silicon Bronze C87850

As drinking water regulations continue to restrict or require total elimination of lead content in plumbing systems, manufacturers are increasingly specifying C87850 eco-brass for new component designs and replacement parts to remain compliant. This silicon brass alloy provides all of the traditional performance manufacturers expect from bronze or leaded parts, while meeting modern lead-free standards on new systems. C87850 castings feature strong wear resistance, very good machinability, high-pressure bearing strength, excellent recyclability, and the ability to withstand marine and industrial environments.

Use C87850 Alloys to Remain Lead-Free Compliant

C87850 was developed to satisfy increasingly stringent lead restrictions in plumbing and drinking water systems throughout North America. This alloy is commonly specified by OEMs looking to manufacture castings that are compliant with:

• Safe Drinking Water Act (SDWA)
• Reduction of Lead in Drinking Water Act
• California AB1953
• NSF/ANSI 372 Lead-Free Certification
• NSF/ANSI/CAN 61 Drinking Water System Components

Why Sand Cast Eco-Brass?

Sand casting offers manufacturers a cost-effective method for producing complex lead-free components without the expense of permanent tooling. The process allows greater design flexibility while reducing material waste through near-net-shape production.

Erie Bronze & Aluminum combines decades of non-ferrous casting experience with modern molding practices to produce high-quality eco-brass castings that meet demanding OEM requirements for dimensional consistency, repeatability, and performance.

Whether you require prototype castings or production quantities, our foundry can supply custom C87850 components tailored to your application.
