Tungsten heavy metal boring bar is manufactured with alloys of 90%-97% tungsten. Its surface is in sintered form or machined form or polished form. Tungsten heavy metal boring bar has the similar properties to the tungsten carbide boring bars, but the different chemical composition can help to reduce brittlement. Owing to the high density combining with tensile strength, tungsten heavy metal boring bar is great in resisting the chatter. So it also have the name as chatter free boring bar or supper chatter free boring bar.
Tungsten heavy metal boring bar is widely used for boring bars, grinding mandrels, tool shafts and types of precision tool that need vibration-damping to ensure smooth running.

Zhuzhou Newmetal Materials Co., Ltd is a refractory metal manufacturer specializing in the raw material and deep-processing product of tungsten, molybdenum, tantalum, niobium, rhenium and tungsten carbide.

• We have conquered the technological difficulties in welding between the tungsten carbide wear-resistant material and stainless steel-based and iron-based. The geometrical tolerance of weldment can be controlled in level A.

• Relying on powder metallurgy institute and engineering materials institute of Central South University, We have established a production-learning-research base to provide powerful technologic support for products R&D. And we have the whole production equipment from mixing to finish machining, including the world’s most advanced cold isostatic pressing machine which can manufacture the widest and longest plate.
