Elevator Counter Weights Tungsten Alloy Weight for Crankshaft/vibration Motor/automobile Wheels/automobile Engines
With regular shape, such as square, rectangle and other iregular shape. It's have excellent electric and thermal characters with high density, which is much higher than Nickel, Titanium and lead. Tungsten alloy also have good mechanical strength and small coefficient of expansion and large elastic modulus,excellent corrosion resistance and machinability.
1. good mechanical strength
2. low thermal expansion
3. good corrosion resistance
4. high radiation absorption (superior to lead)
5. simplified life cycle
6. high density, high strength,high impact resistance and crack resistance, etc.
Tungsten heavy metal crankshaft (also known as Mallory 1000, Densalloy, Fansteel 77, Densimet) is an important part of an engine, for it transfers reciprocating linear piston motion into rotation.
Tungsten heavy metal crankshaft (Densimet) has engineering properties similar to steel, are relatively easy to machine, and can be plated or painted to enhance their corrosion protection. Tungsten heavy metal crankshaft (Densimet) is approximately 50% denser than lead resulting in a higher concentration of mass in a limited area.
Tungsten heavy metal crankshaft (Densimet) from China made by our company is used as balancing weights on crankshafts or in balance shafts in formula 1 racing cars or large diesel engines. Besides, tungsten heavy metal crankshaft (Densimet) can also be used as damper and absorber components in the drive train.

The minimum weight requirements of motor sport formulae are often met with ease as more exotic materials give designers the ability to create lighter and stronger components in the search for greater performance.
tungsten alloy weight helps to provide competitive advantage by giving the ability to add ballast within confined spaces in exactly the correct place to both trim the weight distribution and lower the centre of gravity of a competition car and still meet the minimum weight requirements.
A lower center of gravity can also be achieved by adding tungsten skid plates, which also protects the lower parts of the chassis, especially important in F1 racing car, where a ride-height monitoring plank is used.
Tungsten alloy weight for automobile wheels/automobile engines
Due to its very high density, tungsten alloy vehicle ballast is an ideal material for suppressing vibration in static or moving components.
