Crankshaft weights

　With higher density and lower toxicity, tungsten alloy is always chosen as weights for crankshaft weights and ballast of different vehicles. Compared with steel, tungsten alloy has twice its density and has the advantages of high hardness, good wear resistance, strong corrosion-resistance, high melting point, and high-temperature resistance. In race car competion like F1 formular and other competition, tungsten weight are optium choice.

　The tungsten alloy crankshaft counterweight means that the sum of all the forces is roughly equal to zero at any point in the assembly's rotation, of which the operation is done by the tungsten alloy crankshaft counterweights. The tungsten alloy crankshaft are designed to offset the weight of the rod and pistons. It is critical that the crankshafts must be balanced to customized rod and piston combination.In race cars, aircraft and other high-performance engines, tungsten alloy crankshaft balancing is regarded as one of the most important part to the engine performance for it could suppress vibration for static or moving components.
