Crankshaft is one part of the engine; it can convert the reciprocating straight-line motion of pistons into the rotation.
How does the crankshaft work?
The rods and bearings connect the piston to the crankshaft, when the piston moves up and down, the crankshaft is moved in a circular motion by the rods and bearings.
Advantages of Tungsten Alloy Crankshafts
It is necessary to provide counterweights for the reciprocating mass of each piston and connecting rod to improve balance in engines, and these are typically cast as part of the crankshaft. Lead is cheap but the density is much lower than tungsten heavy alloy, and it is not environmentally-friendly. Tungsten Heavy Alloy is also twice the density of steel, so compared with other materials, it is certainly considered as the most appropriate crankshaft material. Consider its many properties, including:
- Small volume, large density
- High hardness
- High abrasion resistance
- Great anti-corrosion ability
- Strong anti-striking ability
- High melting point
- Environmental friendliness
Therefore, tungsten alloy parts are usually used as counterparts in machines, ships, airplanes, yachts, spaceships, and are highly sought-after in high-performance engines (cars, racing cars, motorcycles, yachts etc.).
We have specialized in manufacturing and supplying WHA (tungsten heavy alloy) for almost 14 years. Our professional knowledge and experience in crankshafts assures our products with high quality (in accordance with ASTM B 777-99) and competitive prices. We supply not only standard tungsten alloy crankshafts, but also manufacture according to your specific requirements.
