What is crankshaft?
The crankshaft, sometimes casually abbreviated to crank, is the part of an engine, which translates reciprocating linear piston motion into rotation. |

How does crankshaft work?
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. We may find the details at http://wikipedia.jaylee.cn/ (Thanks Wikipedia show us the details of what is crankshaft and how the engine works).
Advantages for tungsten alloy crankshaft
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 t as the most appropriate crankshaft material for its properties as follows:
*Small volume but high density
*Excellent hardness
*Superior wearing resistance
*Good corrosion resistance
*Wonderful Shock resistance
*High melting point
*High temperature resistance
*Environmental friendly |

Therefore, tungsten alloy parts can be used as counterweight in machines and vessels as well as aircraft, ships, yachts, space shuttles and anywhere need much heavy but little space, the tungsten heavy alloy crankshaft is widely used in high-performance engines (automobile, racing car, motor, fan, diesel, truck, yacht, jet, fan etc.)
