Tungsten Alloy Bar | Agescan International

Tungsten Alloy Bar

Tungsten alloy bars consist of 85-99% tungsten as well as nickel, iron, copper or other components. The alloys are made by liquid-phase sintering to give a structure consisting of almost pure tungsten particles in a matrix of alloy elements. Tungsten alloy bars enlarge 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.

Description

Tungsten alloy bars consist of 85-99% tungsten as well as nickel, iron, copper or other components. The alloys are made by liquid-phase sintering to give a structure consisting of almost pure tungsten particles in a matrix of alloy elements. Tungsten alloy bars enlarge 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.

We offer various types of tungsten alloy 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. Tungsten alloy bars can be machined into round shapes or square shapes, and it is one of the most important and popular products of tungsten heavy alloy.

Advantages of Tungsten Alloy Bars

Tungsten alloy is often used in making tungsten alloy bars due to its high density ranging from 16.5 to 18.5 g/cm3, about 50 percent higher than lead and much higher than steel. In addition, with a high melting point, tungsten alloy keeps its properties when other metals start to melt under high temperature.

Application of Tungsten Alloy Bars

Typical applications of tungsten alloy bars include weights and counterbalances for aircraft control surfaces and rotor blades, guidance platforms, flywheels, turbines and engine crankshafts; it also can be machined into vibration-reducing knife rests, filaments and fuse masses. Tungsten steel and electrodes with various kinds of heat elements can be mainly used in the manufacture of guns, artillery, rockets, satellites, airplanes and ships. Other applications include radiation shielding, gyro rotors, weapons with armor piercing applications, and high temperature tooling.
