Product Description
Tungsten Balance Weight
What is Tungsten balance weight?Tungsten balance weights are made with a high tungsten content and low amounts of Ni, Fe or Ni, Cu. Some tungsten alloy is added Co, Mo or Cr, etc. The density of tungsten heavy alloy could be as high as 16.8~18.8g/cc. Tungsten heavy metal weight is better in aspects of low toxicity, durability, density, and dimensional stability than lead. Therefore, Tungsten alloy parts can be used as counterweight in machines and vessels as well as aircraft, ships, yachts, and space shuttles need much heavy but little space, the tungsten heavy alloy crankshaft is widely used in high-performance engines (auto-mobile, racing car, motor, fan, diesel, truck, yacht, jet, fan, etc.)
Application
Tungsten balance weight has been widely used in the aerospace industry as counterbalance weight for ailerons, rudders, and elevator parts for fixed and rotary wing aircraft. They are also found with good advantages in aircraft planes including aircraft control faces, rotor blades, trim weights, guidance platforms, balancing of flywheels and turbines, vibration dampening governors, and ballast weights.
Advantages
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
