C44400 is a copper alloy known as Leaded Naval Brass. Here is the typical chemical composition of C44400 copper coil:

Copper (Cu): 71.0 - 75.0%

Lead (Pb): 0.80 - 1.50%

Zinc (Zn): 22.0 - 28.0%

Iron (Fe): Maximum 0.07%

Other Elements: Includes trace amounts of other elements such as sulfur (S), phosphorus (P), and tin (Sn), typically less than 0.05% each.

Key points about the chemical composition:

Copper (Cu): The primary constituent, providing the base metal with its inherent electrical conductivity and corrosion resistance.

Lead (Pb): Enhances machinability and wear resistance of the alloy. The lead content is controlled within specific limits to balance these properties without compromising other characteristics.

Zinc (Zn): A major alloying element that contributes to the strength, hardness, and corrosion resistance of the alloy.

Iron (Fe): Present in trace amounts, it helps in enhancing the alloy's mechanical properties.

Other Elements: Trace elements like sulfur, phosphorus, and tin are included in minimal quantities to refine the alloy's properties and ensure it meets specified standards.



Composition:

1. Copper (Cu): C44400 typically contains around 71.0% to 75.0% copper, providing the base metal with its inherent conductivity and corrosion resistance.

2. Lead (Pb): Approximately 0.80% to 1.50% lead content contributes to improved machinability and wear resistance.

3. Zinc (Zn): Comprising about 22.0% to 28.0%, zinc enhances the alloy's strength and corrosion resistance.
