Tungsten Alloy Rod in Automotive Balance Weight
Tungsten alloy rod is high density tungsten alloy rod used in automotive balance weight for automotive power and transmission systems. Manufactured through powder metallurgy, it has a density of 16.5–18.8 g/cm³ and delivers high mass concentration within limited space, effectively meeting the precision balancing and dynamic balance requirements of crankshafts, flywheels, wheels, drive shafts, and other components. CTIA’s tungsten alloy rod features a uniform and dense microstructure, stable and reliable material properties, high strength, excellent vibration resistance, low coefficient of thermal expansion, and optional non-magnetic characteristics. As an environmentally friendly alternative to traditional lead balance materials, tungsten alloy products are widely used in balancing systems of passenger vehicles, commercial vehicles, racing cars, and new energy vehicles.
