Tungsten Alloy Crankshaft Rod

Tungsten alloy rod have very high melting point and density which are twice than steel and more than 50% heavier than lead, which is important in the case of needing high weights while low volume. What’s more, tungsten alloy rod has high density and high tensile strength, separately ranging from16.5 to18.75 g/ cm and 700 to 1000Mpa. In addition, tungsten alloy rod has good corrosion resistance, weld ability, mach inability and low thermal expansion. Besides, tungsten alloy rod is wearable, resulting in prolong the life of the tungsten alloy crankshaft rod which is so important to companies for saving of regular cost. Finally but not the lastly, tungsten alloy’s harmless to health and environment-friendly which is important in this decades also leading people to adopting tungsten alloy materials for their crankshaft counterweight. The above advantages have made tungsten alloy rod ideal materials for crankshaft.

The tungsten alloy crankshaft rod is a rotating mass, and any rotating mass that isn't perfectly balanced will cause uneven loading on the bearing surfaces that support it. The faster it turns, the worse the problem becomes. So we should not overlook the importance of balancing the engine, as tungsten alloy crankshaft rod enables us to sustain higher engine speeds and gives us reliability.

The tungsten alloy crankshaft rod bearings fit into the lower end of the connecting rod. Tungsten alloy crankshaft rod are fed a constant supply of oil through a hole in the crankshaft Journal. A hole in the upper bearing half feeds a passage in the connecting tungsten alloy crankshaft rod to provide oil to the piston pin.

Reducing engine vibration reduces stress on motor mounts and external accessories, and in big over-the-road trucks, the noise and vibration the driver has to endure mile after mile. A smoother-running engine is a powerful engine as less energy is wasted by the tungsten alloy crankshaft rod as tungsten alloy crankshaft thrashes about in its bearings, which translates into a more usable power at the flywheel.
