Rhenium tungsten probe is a needle made of rhenium tungsten alloy wire containing 3% rhenium. The needle tip of such a probe is processed by a special process with the advantages of high precision, high strength and elastic modulus. So, the probe is more wear-resistant and corrosion-resistant. The surface of the probe is smooth, and the finish can reach Ra0.25 or less.

Tungsten is a superior material for fabricating needle. And tungsten needle is the most important semiconductor test probe. Tungsten probes are mainly used in the final testing stage of processes of semiconductors. And the tungsten probe used to connect the chip to the test board is an important factor that affects contact and electrical characteristics of dies. Generally speaking, the tungsten needle as a probe is to identify good and bad dies, thereby reducing unnecessary packaging cost.

Tungsten needle is often used as an ablation electrode, which is mainly made of 99.99% high purity tungsten, having the characteristics of high melting point and high temperature stability.

Polymer tungsten is a soft radiation shielding material made of tungsten powder and high molecular polymer (one or more of plastic, rubber or thermoplastic elastomer) through extrusion molding, injection molding or compression molding process. And polymer tungsten radiation protection material can play a good role in blocking X-rays, gamma rays and other radiation rays, so it has been used to produce protective clothing and other medical protective products.
