Products Description
Tungsten heavy alloy boring bar is an alternative to tungsten-carbide heavy metal boring bars for better performance and longer tool life. It is also used for boring bars, grinding quills, Arbors, Spindles, Tool Holders, and Shanks to reduce vibrations and chatter.
Tungsten Heavy Alloy Boring Bars are made of Tungsten heavy alloys which have good machining properties, excellent radiation resistance, lower expansion coefficient, high strength and modulus of elasticity which make it extensively used in balance weights for submarine and vehicles, aircraft components, nuclear and medical shields , fishing and sport tackles etc.
features of Tungsten heavy alloy
High Density and High Elastic Modulus:
Tungsten heavy alloy has high density and high elastic modulus, which helps absorb vibrations and reduce chatter during machining. Compared to steel boring bars of the same diameter and overhang length, tungsten alloy bars can reduce deflection by 50%-60% under the same cutting conditions.
Good Machinability:
Although tungsten heavy alloy is quite hard, it still has good machinability and can be processed using traditional methods.
High Wear Resistance:
Tungsten heavy alloy offers excellent wear resistance. Even under high-intensity cutting conditions, it keeps a sharp cutting edge, reducing the need for frequent tool changes.
High Heat Resistance:
Thanks to tungsten's high melting point, the alloy maintains stable performance even at high temperatures, making it ideal for heavy-duty and high-heat machining tasks.
Strength and Durability:
Tungsten heavy alloy retains strong structural integrity under stress and has a long service life.

applications of Tungsten heavy alloy
1. Material for collimators and shielding components in radiotherapy.
2. Balancing weight parts which are used in balancing rotating systems
3. Molds which are used for aluminum casting
4. Kinetic energy materials
5. Source holders for mining
