Tungsten Alloy Boring Bars

Tungsten Alloy Boring Bar 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 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 heavy metal boring bars are manufactured in sintered or polished alloys of 90%-95% tungsten with a nickel-copper-iron-moly matrix. These alloys are very similar to tungsten-carbides but the chemical composition is developed differently to reduce embrittlement. The high density (twice as heavy as steel) and tensile strength (110 kpsi) of this alloy makes the ideal combination for chatter free tools and supper chatter free tools. Heavy metal boring bars greatly enhance boring application by absorbing vibration and drastically reduce chatter, enabling to machine deeper bores with greater precision and finish.
