HomeCopper CNC Machining
Copper is rose red and purple after the formation of oxide film on the surface, copper is second only to silver in electrical conductivity and thermal conductivity, widely used in the electrical industry, motor manufacturing, energy industry, ship propellers, etc., but the strength and hardness is poor.
We understand that each project is unique and these copper parts are custom made to your specifications. Let our copper CNC machining engineers help you craft your vision with precision and professionalism.
Copper Machinability
Copper is so ductile that a drop of copper can be stretched into 2 km of copper wire or pressed into a bed of clear copper foil.
| Application | Various transmission parts and fixed parts, such as cylinder sleeves, connectors, fasteners, gears, twisting and turning parts, etc., all need to copper or copper alloy to reduce wear and lubrication. |
| Advantages | Electrical conductivity, thermal conductivity, corrosion resistance and good processing properties. |
| Disadvantages | CNC machining copper parts in the environment containing active substances are prone to corrosion. |
| Lead Time | Prototype parts delivery time is 1-3 days, mass production depends on the specific quantity, we have additional expedited processing services to meet your needs. |
| Price | $$$ |
| Tolerances | Can be achieved high precision tolerances of 0.0004" (0.01mm) |
| Design for Manufacturability | Before copper can be machined, design requirements and specifications must be sorted out, which contribute to the functionality of copper components. These include reducing the number of part setups, dimensional checking, and preventing deep cavities with small radii. |
