| C37700 | Good strength and forging performance | Valves, plumbing fittings and hardware |
| C26000 | High ductility and corrosion resistance | Electrical terminals, connectors and fasteners |
| H59 | High strength and good machinability | Brass nuts, valves and mechanical components |
| H62 | Good ductility and corrosion resistance | Electrical parts and precision machined components |
| CW614N (CZ121) | Free-cutting brass with excellent chip control | Threaded parts, fittings and precision CNC components |
Properties of Copper Material
Copper combines high electrical and thermal conductivity with useful ductility, strength and dimensional stability for precision components.
Density
Provides a solid, stable structure for connectors, terminals and busbars.
Electrical Conductivity
Ideal for terminals, contact pins, electronic ports and power transmission parts.
Thermal Conductivity
Transfers heat quickly in heat sinks, cooling plates and thermal components.
Hardness
Balances machinability, formability, wear resistance and dimensional stability.
Tensile Strength
Supports moderate loads while retaining useful ductility.
Yield Strength
Helps terminals, clips and conductive structures resist permanent deformation.
Elongation
Supports bending, stamping, crimping and assembly without easy cracking.
Surface Treatments for Copper Machining Parts
Finishing can improve conductivity, solderability, oxidation resistance, wear performance and appearance.
Polishing
Removes machining marks and creates a cleaner, brighter surface.
Anti-Oxidation Protection
Helps reduce oxidation, darkening and verdigris on conductive parts.
Functional Plating
Improves solderability, contact stability, hardness or corrosion resistance.
Texture and Coating
Adds a controlled surface texture, color or protective outer layer.
