Crankshaft is one part of engine; it can convert reciprocating straight line motion of piston 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. 

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 as the most appropriate crankshaft material for its properties as follows:

Small volume, large density

High hardness

High abrasion resistance

Great anti-corrosion ability

Strong anti-striking ability

High melting point

Thermo-stability

Environmental

Therefore, tungsten alloy parts are usually used in counterparts in machines, ships, airplanes, yacht, spaceship, and are highly used in high-performance engines (cars, racing cars, motorcycles, yachts etc.).
