Common copper material
Different copper grades provide varying levels of conductivity, strength, corrosion resistance, and machinability for diverse industrial applications.
| Brass Grade | Características | Aplicaciones típicas |
|---|---|---|
C36000 (C3604) | Excellent machinability and dimensional stability | Precision CNC parts, fittings, connectors |
| C37700 | Good strength and forging performance | Valves, plumbing fittings, hardware |
| C26000 | High ductility and corrosion resistance | Electrical terminals, connectors, fasteners |
| H59 | High strength and good machinability | Brass nuts, valves, mechanical components |
| H62 | Good ductility and corrosion resistance | Electrical parts, precision machined components |
CW614N (CZ121) | Free-cutting brass with excellent chip control | Threaded parts, fittings, precision CNC components |
Density: 8.90–8.96 g/cm³
Copper has a high density, giving machined parts good stability and a solid structure for connectors, terminals, and busbars.
Electrical Conductivity: 80–101% IACS
Copper offers excellent conductivity, making it ideal for terminals, contact pins, electronic ports, and power transmission parts.
Thermal Conductivity: 300–401 W/m·K
Copper transfers heat quickly, so it is widely used for heat sinks, cooling plates, and thermal management components.
Hardness: 40–110 HB
Copper has moderate hardness, balancing machinability, formability, wear resistance, and dimensional stability.
Tensile Strength: 200–360 MPa
Copper provides enough strength for moderate loads while keeping good ductility for precision machined parts.
Yield Strength: 50–300 MPa
Higher yield strength helps copper parts resist permanent deformation in terminals, clips, busbars, and conductive structures.
Elongation: 15–50%
Good elongation allows copper parts to withstand bending, stamping, crimping, and assembly without cracking easily.
Tratamiento de superficies
Copper parts can be finished with polishing, plating, and anti-oxidation treatments to improve conductivity, solderability, corrosion resistance, wear resistance, and appearance.
Tratamiento de superficies | Función principal | Aplicaciones comunes |
Pulido mecánico | Improves brightness and removes machining marks | Decorative parts, small copper parts |
Pulido químico | Cleans and brightens complex surfaces | Batch parts, irregular copper parts |
Electropulido | Creates a smoother and brighter finish | Precision parts, high-end components |
Passivation / Anti-oxidation | Reduces oxidation, darkening, and verdigris | Conductive parts, electronic components |
Tin Plating | Improves solderability and oxidation resistance | Terminals, connectors, electronic interfaces |
Niquelado | Enhances corrosion resistance, wear resistance, and hardness | Mechanical copper parts, connectors |
Silver Plating | Improves conductivity and contact stability | Contacts, terminals, precision connectors |
Gold Plating | Provides excellent oxidation resistance and stable conductivity | High-end electronic contacts and interfaces |
Cepillado | Creates a matte or satin surface texture | Panels, decorative copper parts |
Recubrimiento en polvo | Adds color and surface protection | Housings, decorative structural parts |
