BE0940 Beryllium Foil

Descriptions of Beryllium Foil

Beryllium (Be) is a brittle, steel-gray alkaline earth metal. It is strong, lightweight, and has a modulus of elasticity 50% greater than steel. It is non-magnetic properties and has higher specific heat than any metal. Beryllium retains excellent properties at elevated and cryogenic temperatures, making this fascinating metal an ideal thermal conductor.

Advanced Refractory Metals is a leading supplier of beryllium products. We offer competitive pricing and great lead times on all our materials, and we're capable of supplying custom materials per any specs/drawings you provide us with.
