Manufacturing capabilities
Copper spacer production for demanding assemblies
Copper is selected for its superior thermal and electrical conductivity, as well as its ductility. We machine various copper grades and copper alloys into components tailored to your assembly requirements.
Precision turned parts
CNC turning is ideal for cylindrical copper spacers, sleeves, bushings, pins, and shafts. We control outside diameter, inside diameter, and length to the requirements of your print.
- Custom spacer and sleeve geometries
- Controlled OD, ID, length, and concentricity
- Suitable for pins, shafts, and bushing applications
Precision milled parts
CNC milling supports complex profiles such as flat-faced spacers, brackets, and blocks with slots, pockets, counterbores, and other detailed features.
- Complex profiles and non-round components
- Slots, pockets, counterbores, and flat faces
- Components tailored to your assembly layout
Part configurations
Common copper spacer formats
Every component is manufactured from your engineering prints. We can support standard and application-specific geometries for mounting, alignment, insulation, thermal transfer, and rotating assemblies.
