Machining WNiFe Heavy Tungsten Alloy Crankshafts 90WNiFe For Autoparts

Heavy Tungsten Alloy Crankshafts means that its specific gravity is higher than other materials. High specific gravity tungsten alloy is the best material choice in machinery, ships, aircraft, etc. where counterweight is required but the volume is relatively small! Therefore, tungsten alloy crankshafts are widely used in some high-performance engines, such as racing cars, rowing boats, ships, automobiles, etc.

Introduction and Feature of Heavy Tungsten Alloy Crankshafts

  • The crankshaft is an important part for the engine to withstand shock loads and transmit power. Among the five major components of the engine, the crankshaft is the most difficult to ensure the machining quality. Due to the poor working conditions of the crankshaft, the crankshaft material and blank processing technology, accuracy, surface roughness, heat treatment, surface reinforcement, dynamic balance, etc. are required. are very strict. If the quality of any link cannot be guaranteed, it will seriously affect the service life of the crankshaft and the reliability of the entire machine.

  • Traditional crankshafts are usually made of medium carbon steel or medium carbon alloy steel by die forging. After high frequency quenching or nitriding treatment, the surface hardness and roughness of the journal surface are higher after fine grinding. However, the traditional crankshaft materials can no longer meet the requirements of the rapid development of crankshaft production and use.
