Product Introduction
Composition: C33200 is primarily composed of copper (Cu) and zinc (Zn), with small amounts of lead (Pb) and other trace elements. The typical composition is approximately:
1. Copper (Cu): 63%
2. Zinc (Zn): 35%
3. Lead (Pb): 2%
Properties:
1. Mechanical Properties: C33200 exhibits good strength and ductility, which makes it suitable for forming and bending into coils.
2. Corrosion Resistance: It offers moderate corrosion resistance in most environments.
3. Machinability: C33200 has good machinability, allowing it to be easily fabricated into coils and other shapes.
4. Electrical Conductivity: While not as high as pure copper, C33200 still retains reasonable electrical conductivity, making it suitable for electrical applications where conductivity is not the primary concern.
Standards: C33200 copper alloy conforms to standards such as ASTM B135/B135M, which specify the chemical composition, mechanical properties, and manufacturing requirements for brass strip, sheet, plate, and rolled bar.
C33200 is a copper alloy that falls under the category of low-lead brass. Here is the typical chemical composition of C33200 copper coil:
Copper (Cu): Approximately 62.0 - 64.0%
Zinc (Zn): Approximately 34.0 - 36.0%
Lead (Pb): Approximately 1.5 - 2.5%
Other Elements: Includes trace amounts of other elements such as iron (Fe), tin (Sn), and phosphorus (P), typically less than 0.5% each.
Key points about the chemical composition:
Copper (Cu): This is the primary constituent of C33200, providing the base material with its essential properties such as electrical conductivity and corrosion resistance.
Zinc (Zn): Zinc is the major alloying element in C33200 brass. It enhances the strength, hardness, and machinability of the alloy.
Lead (Pb): Despite being referred to as "low-lead brass," C33200 contains a small percentage of lead. This amount is typically controlled to comply with regulatory standards, especially those related to drinking water applications where lead content must be minimized.
Other Elements: These trace elements are present in very small amounts and can influence the alloy's mechanical and chemical properties, but they do not significantly alter its primary characteristics.
Properties and Applications:
Mechanical Properties: C33200 exhibits good strength, ductility, and machinability, making it suitable for forming into coils and various components.
Corrosion Resistance: It offers moderate corrosion resistance, particularly in freshwater and mildly corrosive environments. However, it may not be as resistant to corrosion as some other copper alloys like aluminum bronze or nickel aluminum bronze.
Electrical Conductivity: While not as high as pure copper, C33200 still maintains reasonable electrical conductivity, making it suitable for electrical and electronic applications where conductivity requirements are moderate.
Applications: C33200 copper coil is commonly used in plumbing fittings, valves, electrical connectors, and components where a combination of strength, corrosion resistance, and machinability is required.
