C33200 is a specific type of copper alloy, known as "High-Leaded Tin Bronze."

C33200 copper bar, known as High-Leaded Tin Bronze, has a specific chemical composition that gives it its characteristic properties. Here is the typical chemical composition of C33200 copper bar:

Copper (Cu): Approximately 82.0% to 85.0%

Tin (Sn): Approximately 7.0% to 9.0%

Lead (Pb): Approximately 7.0% to 9.0%

Zinc (Zn): Maximum of 0.5%

Iron (Fe): Maximum of 0.25%

Phosphorus (P): Maximum of 0.1%

These percentages may vary slightly depending on the specific manufacturer or standard, but they provide a general idea of the composition of C33200 copper bar.

Key points about the chemical composition:

Copper (Cu): This is the primary element in C33200, forming the bulk of the alloy and providing its base properties, such as conductivity and corrosion resistance.

Tin (Sn) and Lead (Pb): These elements are added to improve the alloy's mechanical properties, including strength, wear resistance, and machinability. Tin contributes to the alloy's strength and hardness, while lead enhances machinability and lubricity.

Zinc (Zn), Iron (Fe), and Phosphorus (P): These elements are present in trace amounts to control impurities and enhance specific characteristics, such as machinability and casting properties.

Composition: C33200 is primarily composed of copper (Cu), tin (Sn), and lead (Pb). Typical composition ranges are approximately 83% copper, 8% tin, and 9% lead. This composition gives it its characteristic properties.

Mechanical Properties:

Strength: C33200 bronze offers good strength, making it suitable for applications where mechanical strength and load-bearing capabilities are required.

Wear Resistance: It has excellent wear resistance, which is beneficial for components subject to friction and abrasion.

Toughness: The alloy exhibits toughness, allowing it to withstand heavy loads and stress without deformation.

Machinability: One of the standout features of C33200 is its excellent machinability. It can be easily machined, cut, and formed into various shapes and components, which is advantageous for manufacturing processes.

Corrosion Resistance: C33200 provides moderate corrosion resistance, particularly in environments where it is not exposed to severe conditions. This makes it suitable for use in various industrial and marine applications where corrosion resistance is required but not critical.

Standards: C33200 is typically specified according to ASTM (American Society for Testing and Materials) standards, such as ASTM B505 for copper alloy continuous castings, ensuring consistency and quality in its production and use.

Applications:

Bearings and Bushings: C33200 is commonly used for manufacturing bearings, bushings, and other components in machinery and equipment due to its wear resistance and load-bearing capabilities.

Machine Components: It finds applications in gears, valve components, pump parts, and fittings where its combination of strength, machinability, and wear resistance is advantageous.

Marine and Industrial Uses: While not as corrosion-resistant as some other copper alloys like naval brass, C33200 can still be utilized in marine environments for certain components that do not require high corrosion resistance.
