Tungsten parts can be used in refractory alloys for hand gas turbine blades, rocket nozzles, missiles, nuclear reactor components, etc. It can also be used as navigation gyroscope rotors, balance weights and brakes for automatic watches, etc.
You will receive a complementary material cert in the safely packaged shipment. All material is lot controlled, stress relieved, and formed through high temperature pressing and sintering processes.
The strength and hardness of tungsten alloy are generally higher than that of pure metal, the resistance is larger than that of pure gold, the resistance temperature coefficient is small, and it has good comprehensive mechanical properties. Therefore, as a non-ferrous metal, tungsten has very high strength and hardness. Because of this characteristic, tungsten carbide with high hardness and wear resistance is widely used in cutting tools and mining tools.
They can also be used in some other top precision fields, such as mobile phone vibrators, the pendulum for the clock, automatic watch balance, shockproof knife tools, and flywheel weight.
