Tungsten needle is an elongated tungsten product made of pure tungsten or tungsten alloy, having the advantages of high temperature resistance, high hardness, and good conductivity. Tungsten needle can be used as an electrode material for argon arc welding (the fastest growing and most widely used welding technology at home and abroad), as a probe needle for detecting instrument, or as a dissection needle for various minimally invasive surgery.

Ultrathin tungsten needle has advantages of high hardness and strong ductility. Also, it is not easy to break with durability. The diameter of tip of tungsten needle can reach micron level, which can be used to dissect and separate individual human cells, such as inner ear labyrinth cells. Some experts use 0.32mm tungsten wire to prepare ultrathin tungsten needles. They pre-machined the tips of fine tungsten wire blanks into needle-shaped, sickle-shaped, or hook-shaped needles. The diameter of the tip of these tungsten needles is generally 3 to 10 μm, and the smallest diameter can reach 1.5 μm.

Tungsten heavy alloy is also called tungsten alloy. The main component of tungsten alloy can be W-Ni-Fe, W-Ni-Cu or W-Ni-Cu-Fe, among which other metals such as cobalt, molybdenum, and chromium can also be added. The density of tungsten heavy alloy is twice that of steel, and 1.5 times of lead (conventional radiation shielding material). Moreover, tungsten alloy is an environmentally friendly material, which is non-toxic and pollution-free, so it is more suitable for collimator applications as a radiation protection material than heavy metal lead.
