Red Brass C99500

Leaded Red Brass Castings with Alloy C99500

Copper alloy C99500 is a high-strength casting alloy specified by OEMs that require industrial components that provide exceptional durability, dimensional stability, corrosion resistance, and post-casting machinability. Sometimes referred to as leaded red brass by casting supply companies, C99500 actually contains minimal allowable lead and relies primarily on a combination of copper, nickel, iron, silicon, zinc, and aluminum to deliver desired performance characteristics.

Erie Bronze & Aluminum is now offering custom C99500 sand casting services for OEMs demanding durable non-ferrous components with complex shapes, features, and variable volumes. Contact us today for a quote.

Why C99500 Leaded Red Brass?

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.

C99500 provides manufacturers with strong, rigid, ductile, and corrosion-resistant castings that can be exposed to heavy mechanical loads or demanding environments. The alloy itself offers a minimum tensile strength of approximately 70,100 PSI and a minimum yield strength of 39,900 psi, making it an optimal alloy choice for rugged castings that must retain their dimensional proportions under extreme loads.

Common applications include valve components, mining equipment, marine hardware, gears, electrical components, and other industrial components where long-term durability and machinability are essential to the final application.

C99500 for ASTM B763 Valve Applications

C99500 is often specified for copper-alloy sand castings for valve components under the ASTM B763/B763M standards. This set of specifications establishes applicable chemical composition, mechanical properties, and manufacturing requirements for copper-alloy sand-cast valve components. Using C99500 specifically for valve castings offers several advantages to manufacturers.

• High tensile and yield strength
• Strong resistance to deformation under loads
• Enhanced machinability for secondary finishing requirements
• Corrosion-resistant and resistant to salt-spray or marine conditions
• Exceptional dimensional stability in heavy-duty components

Why Sand Cast C99500?

Sand casting provides manufacturers with a flexible and cost-effective method for producing C99500 components with complex shapes, substantial cross-sections, and near-net-shape geometries. This can reduce material waste and limit the amount of secondary machining required.

Erie Bronze & Aluminum combines decades of non-ferrous casting experience with modern molding practices to produce C99500 castings with consistent dimensions, repeatable performance, and the durability required for demanding OEM applications.

Whether you require valve components, mining parts, marine hardware, or other industrial castings, our foundry can supply custom C99500 components based on your drawings and production requirements.
