Tungsten alloy crankshafts for automotive parts

What is a tungsten alloy crankshaft?

Tungsten alloy crankshaft is an important component of an engine made of tungsten alloy (90-97)% W Ni Fe or (90-97)% W Ni Cu alloy, which is mixed with tungsten powder, nickel powder, and iron powder, followed by a series of processes such as pressing, sintering, heat treatment, and machining. After the main rotating components of the engine are equipped with connecting rods, they can withstand the up and down (reciprocating) motion of the connecting rods and become cyclic (rotating) motion. The rotation of tungsten alloy crankshaft is the power source of the engine.

Why use high density tungsten alloy as crankshaft material?

Because high density tungsten alloy materials have the following advantages:
Compared with other materials, tungsten alloy has advantages such as small volume, high density, high hardness, high wear resistance, strong corrosion resistance, strong impact resistance, high melting point, high temperature resistance, and environmental protection. The density of high density tungsten alloy is twice that of lead, and it is also very environmentally friendly. Therefore, tungsten alloy is definitely the most suitable crankshaft material.
Tungsten alloy crankshafts can be divided into two categories: tungsten alloy counterweight crankshafts and tungsten alloy power crankshafts
Tungsten alloy counterweight crankshaft is used to balance the rotational inertia force and torque generated by the connecting rod big end, connecting rod journal, and crankshaft, making the engine crankshaft run smoothly. Tungsten alloy counterweight crankshafts are sometimes integrated with the crankshaft as an extension, while others are individually made into parts and fixed to the crankshaft with bolts.
The tungsten alloy power crankshaft is connected to the piston, which converts the up and down (reciprocating) motion of the connecting rod into cyclic (rotating) motion to achieve power transmission of the crankshaft.
           

Application of High Density Tungsten Alloy in Other Industries:

Tungsten alloy parts are often used as counterweights for machines, ships, airplanes, yachts, spacecraft, and other places that require small volume and large weight. Tungsten alloy is widely used in high-performance engines (cars, racing cars, motorcycles, trucks, yachts, etc.)
