:: FAQ

AlN vs alumina for heat sinks?

AlN conducts heat ~8× better than 96% alumina and matches silicon's expansion — choose it where thermal density rules.

Is AlN a safe BeO replacement?

Yes — AlN delivers comparable thermal performance without beryllia's toxicity handling burden.

What sizes can you make?

Substrates and plates from a few mm up to ~200 mm, lapped to tight flatness on request.
