Leaded Tin Bronze C93200 Round Bars

Reliable, Machinable, and Long-Lasting Alloys for Demanding Applications

At N S Enterprises, we manufacture and supply a premium range of Leaded Tin Bronze Products, known for their excellent machinability, corrosion and abrasion resistance, and long service life. These alloys are engineered to meet the performance demands of industrial, marine, and mechanical environments.

Leaded Tin Bronze alloys typically contain 7% to 15% lead, which enhances their free-cutting capabilities, thermal conductivity, and lubricity. Alloy C93200—often referred to as the "workhorse" of this alloy family—is widely used in bearing applications due to its well-balanced properties.

• Superior Machinability: Lead content improves cutting efficiency, making these alloys ideal for precision machining.

• Corrosion & Abrasion Resistance: Well-suited for harsh operating conditions, especially in marine and industrial environments.

• Extended Service Life: Reliable performance with reduced maintenance requirements.

• Good Thermal Conductivity & Lubricity: Ensures smooth operation in dynamic parts and reduces wear.

• Pressure Tightness: Enhanced by the presence of lead, making it suitable for high-pressure applications.

• Anti-Friction Properties: High lead content, dispersed as a separate phase, offers excellent sliding characteristics.

• Relatively High Ductility

• Lower Mechanical Strength Compared to Tin Bronzes

• Presence of δ-phase in Alloys with >13% Tin – contributing to brittleness

• Reduced Ductility in Tin Bronzes with High Tin Content

• Lead Additions Improve Pressure Resistance and Machinability

Leaded Tin Bronze products are used across various sectors, including:

• Wire and Cable Connectors

• Electrical Plug-Type Connectors

• Doorknobs, Screws, and Nuts

• Rolling Mill Bearings

• Bushings for Corrosive Environments

• General Bearing and Sliding Applications

• Shipping and Marine Components

• Valve and Pump Assemblies
