Polymer tungsten surgical glove is a new type of surgical glove made using natural rubber emulsion and tungsten powder as raw materials through special processing technology. Wherein, polymer tungsten is also known as tungsten resin or tungsten rubber. Such gloves have merits, such as excellent radiation shielding performance, toughness, bendability, and solvent resistance.

Sharpen tungsten needle is made using pure tungsten (W> 99.95%) or tungsten alloy (W>98%) as raw materials, and has the characteristics of wear resistance, corrosion resistance and high temperature resistance. It can be a tungsten needle sharpened at one end or a tungsten needle sharpened at both ends. In a word, it is a sharpened tungsten needle.

Tungsten needle applied for spray point has better performance than traditional steel wire or stainless steel wire. For example, such an electrostatic discharge needle has higher melting point, higher hardness, and longer service life, etc. It also has the characteristics of good ion release effect, and long ion transmission distance. In addition, the tip of needle is not easy to get dull, and is easy to clean.

Contact resistance of tungsten probe will affect the reliability of wafer testing in semiconductor manufacturing processes. Therefore, in order to improve the accuracy of test results, some experts have proposed a method for testing the contact resistance of tungsten probe.
