Characteristics of Tungsten Sputtering Targets

1) High purity, the purity of the target after sintering and forging can usually be higher than 99.95%. Generally speaking, under the condition that other conditions remain unchanged, the higher the purity of the target material, the better the electrical properties of the resulting coating, and the less likely the corresponding circuit is to be short-circuited or damaged.

2) The cost is relatively reasonable, and the speed of direct pressing by powder metallurgy is faster, which can effectively shorten the production cycle and thus reduce the cost.

3) High density, the target density after sintering and forging can reach more than 19.1g/cm³.

4) The deflection strength is high, and the composition and structure of the finished target produced by ultra-fine pure tungsten powder are relatively uniform and consistent.

5) Good thermochemical stability, not prone to volume expansion or contraction, chemical reaction with other substances, etc.

6) Low resistance, will not make the circuit generate unnecessary energy.

In addition, it has the characteristics of high melting point, high elasticity, low expansion coefficient, low vapor pressure, non-toxic and non-radioactive
