A wide range of metal fasteners is commonly available for standard applications, but not for applications at very high temperatures or in highly corrosive environments. These common fasteners are often not up to the job and high-performance refractory metals are needed. Goodfellow USA, Coraopolis, Pa., offers a range of refractory metal fasteners (nuts, bolts, and washers) ranging in size from M3 to M6 for situations that involve high temperature, high voltage, magnetism, and harsh corrosive environments.
All four metals currently offered—tungsten, tantalum, niobium and molybdenum—are chemically inert and have:
- A melting point above 2400˚C
- High hardness at room temperature
- Relatively high density
- Stability against creep deformation at very high temperatures
Depending on the metal being used, these high-tech fasteners be used for:
- Radiation shielding
- Armor
- Atomic reactors
- Jet engine parts
- Gas turbines
- Rocket subassemblies
- Airframe systems
- Heat-resisting and combustion equipment
- Chemical processing
- Semiconductors
- Industrial motors
