La description
  Crankshaft is one part of engine; it can convert
reciprocating straight line motion of piston into rotation.
  The rods and bearings connects the piston to the
crankshaft, when the piston moves up and down, the crankshaft is
moved as describing a circle by the rods and bearings, then, the
crankshaft is rotating.Â
  It is necessary to provide counterweights for the
reciprocating mass of each piston and connecting rod to improve
balance in engines, and these are typically cast as part of the
crankshaft. Lead is cheap but the density is much lower than
tungsten heavy alloy, and it is not environmental friendly, as for
steel, tungsten heavy alloy are more than twice the density of it,
so compared with other materials, tungsten heavy alloy is certainly
considered as the most appropriate crankshaft material for its
properties as follows:
Small volume, large density
High hardness
High abrasion resistance
Great anticorrosion ability
Strong antistriking ability
High melting point
Thermostability
EnvironmentalÂ
  Therefore, tungsten alloy parts are usually used in
counterparts in machines, ships, airplanes, yacht, spaceship, and
are highly used in highperformance engines (cars, racing cars,
motorcycles, yachts etc.).
  We specialize in manufacturing and supplying WHA
(tungsten heavy alloy) for almost *4 years. Our professional
knowledge and experience in crankshaft assures our products with
high quality (in accordance with ASTM B ****9) and competitive
price. We supply not only standard tungsten alloy crankshaft, but
also manufacture according to your specific requirements.
