:: 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.
