H63 is a type of copper alloy, specifically a copper-zinc alloy. Here are the key details about H63 copper strip:

Chemical Composition:

Copper (Cu): Approximately 60.0% - 63.0%

Zinc (Zn): Remaining balance (37.0% - 40.0%)

Lead (Pb): Maximum of 0.05%

Iron (Fe): Maximum of 0.1%

Phosphorus (P): Maximum of 0.01%

Other trace elements may be present in small amounts.

Key Features and Properties:

Corrosion Resistance: H63 offers good corrosion resistance in various environments, including freshwater and non-oxidizing acids.

Machinability: It has excellent machinability due to its composition, making it easy to work with for shaping, cutting, and drilling.

Electrical Conductivity: H63 has good electrical conductivity, though not as high as pure copper.

Strength: It has moderate strength compared to other copper alloys, suitable for applications where mechanical strength is required along with corrosion resistance.

Applications:

Electrical Components: H63 copper strip is used in electrical connectors, switches, terminals, and other components where both electrical conductivity and corrosion resistance are important.

Decorative Uses: Due to its attractive golden color and ease of machining, H63 is used in decorative applications such as architectural trim, jewelry, and artistic installations.

Plumbing and HVAC Systems: It finds use in plumbing fittings, valves, and HVAC components where corrosion resistance and machinability are beneficial.

Industrial Equipment: H63 is employed in various industrial applications, including gears, bearings, and fasteners, where a balance of strength and corrosion resistance is required.

Automotive Applications: It can be used in automotive components such as radiator cores, heater cores, and fittings.
