Common questions
All questionsHow do I choose between copper, aluminium, silver and silicon carbide composites?
Each matrix balances conductivity, expansion, weight and electrical behaviour differently. Share your thermal and expansion targets, geometry and joining method. We compare options in technical review.
Can diamond content predict composite performance?
No. Conductivity, expansion and electrical behaviour depend on formulation and processing, not diamond content alone. Values are confirmed for your application before supply.
What do you need from me to quote a composite?
Matrix material, thermal and expansion targets, dimensions, flatness, surface finish or plating, and how the part will be joined. A drawing helps. Evaluation samples may be agreed where appropriate.
