The use of high specific gravity tungsten alloy counterweights optimizes the mechanical properties and also helps to meet the requirements of people for balance control of industrial machinery products. The high density and small size allow the physical dimensions of the components to be greatly reduced. This allows for better control of weight distribution and increased sensitivity.
Because of its high density, good mechanical strength and easy processing, tungsten-based high specific gravity alloy counterweights are widely used in aerospace, defense industry, automotive industry, sports equipment, oil drilling, electronics industry and other industries. They are mainly used as balancing blocks for aircraft; tungsten crankshaft balancing blocks and chassis tungsten alloy counterweights in Formula 1 racing cars or large diesel engines; tungsten weighted rods for oil drilling; tungsten alloy dart rods; golf ball counterweights; racing car counterweights; cell phone and game machine oscillators; gyroscopes for aerospace; watch pendulums; balancing counterweights etc.
