Refractory metals are metals that are extraordinarily resistant to heat and wear.
Here at SMF those are the kind of metals that we use, when fabricating.
Molybdenum – Molybdenum is a very hard, pure element with an extremely high melting point of around 2620°C, it has a high thermal conductivity and is corrosive resistant to glass and other metals.
Applications include; sintering trays and boats, charge carriers, aerospace parts, plasma spraying nozzles and electrodes, sputtering targets, furnace components, glass stirrers, and medical parts.
Tantalum – Tantalum is generally made from sintering the powdered ore to produce a metal with an extremely high melting point of approximately 2990°C. It has an excellent resistance to corrosion against molten metals and liquids, is biocompatible and has very high conductivity.
Applications include; heat exchanger tubes, charge carriers, capacitors, electrodes and grounding rings, jet engine parts, missile parts and vacuum furnace parts.
