Bronze & High-Leaded Bronze 
Bronze and high-leaded bronze are some of the most commonly used metals for heavy machinery parts fabrication, and it’s for a good reason.
Bronze Alloy C90500 Explained
C90500, also known as SAE 62 and Gun Metal, is a bronze alloy primarily composed of approximately 86 to 89 percent copper, 6 to 8 percent tin, 2 to 5 percent lead, and small traces of zinc and other elements. This alloy is valued for its unique blend of mechanical strength and corrosion resistance, making it a top choice for high-performance industrial applications.
Key Characteristics of C90500 Bronze
- High Strength and Durability
Designed to withstand heavy loads and high-stress environments, making it ideal for pressure-containing applications. - Excellent Wear Resistance
Its hardness and anti-friction qualities make it well-suited for bearings, bushings, and other components subject to constant movement. - Superior Corrosion Resistance
Outstanding resistance to steam, salt water, and brine, making it a go-to choice in marine and industrial fluid-handling systems. - Reliable Machinability
Despite its strength, C90500 machines well, allowing for precise tolerances and clean finishes. - Thermal Stability
Performs well in high-temperature environments without sacrificing performance.
Also referred to as Gunmetal Bronze or C905 Bearing Bronze, this alloy has a long history of use in both industrial and marine applications. Its excellent resistance to corrosion by salt water, brine, and steam makes it particularly well-suited for shipbuilding and heavy-duty equipment.
C90500 is ideal for:
- Pump and Valve Components
- Bearings and Bushings
- Steam Fittings
- Marine Hardware
- Hydraulic Components
- Heavy-Load Mechanical Parts
Thanks to its outstanding mechanical properties and long-term durability, C90500 remains a top choice in sectors such as power generation, shipbuilding, and industrial machinery. Its combination of hardness, corrosion resistance, and pressure containment capacity makes it a reliable solution for both legacy equipment and modern systems.
