ASTM B760 Tungsten Weight Tungsten Counterweight For Crankshaft
Introduction
Tungsten Weight Tungsten Counterweight is added in auto racing to stabilize the car and ensure the car is within the required weight class for the race by putting more weight over the drive wheels.
Feature of Tungsten Counterweight
1. High density
2. High wear-resistant
3. High thermal conductivity with low thermal expansion coefficient
4. High vibration-damping capacity and high Young's modulus
5. High oxidation resistance and corrosion resistance

Application
Tungsten Counterweight is used in crankshaft as a counterweight. The tungsten alloy crankshaft counterweights are designed to offset the weight of the rod and pistons. The crankshafts must be balanced to customized rod and piston combinations. As tungsten alloy has high density, adding WHA balance weight into the racing car has a good effected in optimizing the performance of the racing car during the racing process, which contributes to better control of the car's movement.
