FAQ

Can you supply crucibles to a specific drawing?

Yes, custom machining from BN blanks is our specialty. Send us your CAD drawing or detailed sketch for a prompt quote.

What is the lead time for custom crucibles to the UK?

Typically 4-8 weeks for custom designs, depending on complexity. Standard items may ship sooner.

Is Hot-Pressed BN suitable for use with molten aluminium or reactive metals?

Yes, its non-wetting property and chemical inertness make it excellent for Al, Mg, and many alloys.
