Tungsten Alloy Bar

Tungsten Alloy Bar
Tungsten alloy bar is consist of 85-99% tungsten with balanced commonly nickel and iron or copper. The alloys are made by liquid-phase sintering to give a structure consisting of almost pure tungsten particles in a matrix of the alloy elements. 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. In addition, it can be used to cut a tapered hole.

There are various types of tungsten alloy boring bars. The tungsten alloy bar may be supported on both ends, but that only works 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 Bar Advantages

Tungsten Alloy Bar
Tungsten alloy is often used in making tungsten alloy bar because it has a density ranging from 16.5 to 18.5 g/cm3, about 50 percent higher than lead and much higher than steel. It is easily machined, so designers of tungsten alloy boring bars can choose their shapes accordingly without worrying about the properties. In addition, The product is less prone to chipping and breakage with good extensibility, has high melting point, wide working temperature range. When other metals start to melt while tungsten alloy keeps its properties.

Tungsten Alloy Bar Application

Typical Applications of tungsten alloy bar apart from boring bars, include weights and counterbalances for aircraft control surfaces and rotor blades, guidance platforms, counterbalances for flywheels, turbines and engine crankshafts, vibration reducing 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.
