Copper for CNC-machined conductive contacts, heat-transfer components and electrical hardware. Pure copper and copper alloys trade conductivity against strength and machinability. Use the drawing grade and required electrical or thermal properties.
How should I select the grade?
Pure copper and copper alloys trade conductivity against strength and machinability. Use the drawing grade and required electrical or thermal properties. Material availability, stock size and certificate requirements are confirmed during quotation; a listed grade is not a stock guarantee.
What affects machining and inspection?
Review burrs, surface oxidation, deformation and contact-surface protection. Functional tolerances depend on part geometry, material condition, fixturing and measurement method, not only the material family.
What should I specify for finishing?
State the finish standard, thickness, color or texture, masking and functional surfaces. Consider coating build in fits and threads. Approve any material or finishing substitution in writing.
Material quotation checklist
Send the exact grade and condition, 2D drawing, STEP model, quantity, critical features, service environment and traceability requirements. Tecpreva can review machining suitability and proposed alternatives before production.
