ASTM B760 Tungsten Products Tungsten Worm Weights
Introduction
ungsten Worm Weights are 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.
Tungsten alloys are used in crankshafts as 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
effect in optimizing the performance of the racing car during the
racing process, which contributes to better control of the car's
movement.
Feature
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
