High-tech metal fasteners now available for specialized applications
Our specialty is metal fasteners (nuts, bolts and washers) to
our catalog of products available from stock for quick delivery. Molybdenum,
tantalum, niobium and tungsten nuts, bolts and washers in sizes ranging from M3
to M6 provide an impressive array of properties that address the needs of a
variety of high-tech applications.
These metal fasteners complement the ceramic
fasteners launched last year, and offer a solution where more standard metal or
plastic fasteners would not be suitable, such as applications involving high
temperature, high voltage, magnetism, or harsh conditions that would quickly
corrode or wear away other materials.
As refractory metals, all four have a melting
point above 2400 ˚C, high hardness at room temperature, are chemically inert,
have relatively high density and are stable against creep deformation at very
high temperatures.
Material Characteristics and Applications
Molybdenum: maintains its strength at high temperatures, making molybdenum
fasteners ideal for applications where both high temperature and strength are
needed. These fasteners are used in the semiconductor industry, the manufacture
of armor and aircraft parts and in industrial motors.
Tantalum: has a corrosion resistance similar to glass but the mechanical
properties of a metal, making it an excellent choice for extremely corrosive
environments. Fasteners made from tantalum can be found in the chemical processing,
mining, energy, pharmaceutical and metal processing industries. Tantalum is
also radio-opaque, making tantalum fasteners useful in x-ray applications.
Niobium: finds application in atomic reactors because of its corrosion
resistance. Fasteners made from niobium or from nickel-, cobalt-, and
iron-based superalloys containing niobium are found in jet engine parts, gas
turbines, rocket subassemblies, advanced airframe systems, and heat-resisting
and combustion equipment.
Tungsten: has the highest melting point of all metals (3410 ˚C) and is
often the base of a range of tungsten-copper-nickel alloys used for radiation
shielding; these alloys provide a 50% increase in density compared to lead.
Fasteners made from tungsten and its alloys can, therefore, be used in
radiation shielding applications and are also used in military applications
(e.g., armor).
