Tungsten alloy bar is made from tungsten alloy with the shape of round and square. Tungsten alloy boring bar is one important type of tungsten alloy bar.
 |
In machining, boring process of tungsten alloy bar is enlarging a hole that has already been drilled or cast by means of a single-point cutting tool to achieve greater accuracy of the diameter of a hole such as in boring a cannon barrel. And it also can be used to cut a tapered hole.
There are various types of tungsten alloy boring bar. The tungsten heavy alloy bar may be supported on both ends which only work if the existing hole is a through hole or it may be supported at one end. Line boring implies the former. Back boring is the process of reaching through an existing hole and then boring on the "back" side of the work piece. |
Tungsten Alloy Advantages
Tungsten alloy are often used in making tungsten alloy bar because it has a higher density ranging from 16.5 to 18.5 , about 50 percent higher than lead and much higher than steel. Tungsten alloy is easily machined, so that designers of tungsten alloy boring bar for instance can decide their favorable shape without worried about the property. Then tungsten alloy is less prone to chipping and breakage with good extensibility. In addition, tungsten alloy has high melting point, so in the high temperature, other metal starts melting while tungsten alloy keeps its property. |

Tungsten Alloy bar Application
Typical Applications of tungsten heavy alloy bar include weights and counterbalances for aircraft control surfaces and rotor blades, guidance platforms, counterbalances for fly wheels, turbines and engine crankshafts, vibration damping governors, filaments and fuse masses, ingredient kinds of heat-resistant steel and electrode, mainly used to guns, artillery, rockets, satellite, airplane and ship. Other applications include radiation shielding, gyro rotors, weapons including armor piercing applications, and high temperature tooling.
