Tungsten Alloy Friction Bar

Tungsten alloy friction bar has good abrasion resistance, high resistance to sliding friction, excellent impact resistance, which can withstand strong external shock, internal overload, pressure fluctuations. It is non-toxic and environment-friendly, which will not cause environmental pollution and harm to human health.

tungsten alloy friction bar pictureWith the increase of oil extraction, the oil on the surface of the oil decreases. In order to ensure the use of oil, people gradually develop into deep wells and steep wells, but the difficulty of oil extraction gradually increases. Therefore, the friction strip of tungsten alloy has the characteristics of good wear resistance and good impact resistance, which can meet the requirements of petroleum machinery industry.
