    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. 
    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
Environmental 
    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.
