H63 is a type of copper alloy that is primarily used in China and is equivalent to C26800 brass in the United States. Here are the key details about H63 copper coil:

Chemical Composition:

1. Copper (Cu): Approximately 62.0 - 65.0%

2. Zinc (Zn): Approximately 34.0 - 37.0%

3. Lead (Pb): Maximum 0.07%

4. Iron (Fe): Maximum 0.05%

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

Properties:

1. Mechanical Properties: H63 copper alloy exhibits good strength and ductility due to its composition of copper and zinc. It is suitable for applications requiring moderate strength and ease of fabrication.

2. Corrosion Resistance: It provides moderate corrosion resistance, making it suitable for general-purpose applications where exposure to atmospheric conditions occurs.

3. Machinability: H63 has good machinability, allowing for easy cutting, drilling, and forming during manufacturing processes.

4. Electrical Conductivity: While not as conductive as pure copper, H63 retains sufficient electrical conductivity for many electrical and electronic applications where moderate conductivity is acceptable.

Standards: H63 copper alloy typically complies with Chinese standards such as GB/T 4423-2007 (Copper and copper alloy rods) and GB/T 4428-2012 (Copper and copper alloy strips).

In summary, H63 copper coil, or C26800 brass, is valued for its combination of strength, corrosion resistance, machinability, and aesthetic appeal. Its composition and properties make it suitable for a wide range of applications in various industries where these characteristics are essential.

H63 copper coil, which corresponds to C26800 brass in international standards, has the following typical chemical composition:

Copper (Cu): Approximately 62.0 - 65.0%
