Tungsten needle, named Tungsten rod. They are a small rod with high purity tungsten material.it has high hardness and High temperature resistance. So this is common in industry,medicine and electron. In below. We will introduce the tungsten needle.

1. High hardness. The hardness for tungsten needle will higher than other metal. So it is very durable and not easy broken. In medicine. The doctor make any operation will use this tungsten needle. So they can precision cutting and Remove small thing. In other fields. Like electron and automotive industry. The tungsten needle is the common material.

2. High temperature resistance: The tungsten needle can bear high temperature.in welding and cutting metal. High temperature is necessary.as it can Melting and cutting metal. But for other material. They will be melting and cutting metal in high temperature.but tungsten needle can bear it and keep its integrity

3. corrosion resistance: Negative ion discharge tungsten needle has corrosion resistance and Not easy to rust.

4. chemical stability：Electrostatic electret has good  chemical stability in high temperature and high pressure.For example: The tungsten needle can produce semiconductor and other microelectronic components.because it won’t have Chemical reaction occurs.then can ensure high-quality performance of products.

5. economical and practical：Thought  the price for tungsten is expensive than other material. But its high hardness and no need repair. So the using life is longer and cheaper cost. So this tungsten needle is economical and practical.
