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.
Tin Bronze Alloy C90700
C90700 is a high-tin bronze alloy primarily composed of approximately 88% copper, 10–12% tin, and trace amounts of other elements such as phosphorus and lead. This alloy is known for its exceptional strength and wear resistance, making it a popular choice in applications that demand high performance under heavy loads and challenging conditions.
Key Characteristics:
- Excellent Wear Resistance
- High Strength and Hardness
- Good Corrosion Resistance (especially in seawater)
- Outstanding Load-Bearing Capabilities
- Strong Performance in Both Dry and Lubricated Conditions
- Good Machinability
- Excellent Casting Properties
Also referred to as CDA 907, C907 Bearing Bronze, or Gun Metal, this alloy has a long-standing history of use in demanding mechanical applications, particularly where strength and resistance to fatigue are critical.
C90700 is particularly well-suited for:
- Bearings
- Bushings
- Gears
- Pump Components
- Steam and Water Fittings
- Valve Components
- Heavy-duty Mechanical Assemblies
With its excellent mechanical properties and resistance to both wear and corrosion, C90700 is widely used in the marine, industrial, and manufacturing sectors. It is especially favored for its reliable performance in submerged and high-pressure environments.
Whether you're designing for longevity, high strength, or stability under tough conditions, C90700 Leaded Tin Bronze provides the durability and reliability needed for industrial excellence.
