Tungsten Alloy Crankshaft Counterweights in Motorbike

Tungsten alloy is an excellent material to manufacture tungsten alloy crankshaft counterweights in motorbike. All engines need perfectly balanced crankshafts to ensure optimized performance. If a crankshaft is not correctly balanced, the consequences can be severe. 

These include reduced lifetime, excessive vibration and a loss of power from the engine. This is even more important in high performance engines and high-power diesel units. Stresses caused by imbalance in these engines can cause early failure. Here are two advantages tungsten alloy crankshaft counterweights possess in motorbike

High Density

The density of tungsten is 19.25 times that of water, comparable to that of uranium and gold, and much higher (about 1.7 times) than that of lead. The high density of tungsten alloy means it can be used to produce compact, highly durable tungsten alloy crankshaft weights for use in crankshaft balancing. Tungsten alloy crankshaft weights can be placed in the precise location where they are needed to provide optimum performance. Tungsten alloy crankshaft weights are smaller than equivalent steel weights which means external balancing may not be needed in engines where internal space is limited. High performance engines used in motorsport and supercars will use crankshaft counterweights manufactured from tungsten in order to reduce the size of the counterweight and with it the overall profile of the crankshaft, The benefits of improved engine performance delivered by a balanced crankshaft are thus enhanced by an engine with a lower center of gravity that can be positioned lower down in the vehicle giving the vehicle itself a lower center of gravity.

High Melting Point and Durable

Tungsten has the highest melting point of all the elements discovered, melting at 3422 °C (6192 °F, 3695 K). It also has the highest boiling point, at 5930 °C (10706 °F, 6203 K). This can be hugely beneficial in motorbike’s crankshaft (particularly when compared to other common metals). It produces a large amount of heat when engine is running at a very high speed. The heat it produces can even melt the crankshaft made by other materials. So, tungsten alloy is the best option for crankshaft.
