Tungsten Target
Tungsten targets produced by Achemetal Tungsten & Molybdenum Co., Ltd. include tungsten plane targets (tungsten round targets and tungsten strip-type targets) and tungsten rotating targets.
Tungsten plane targets are formed by processing high-quality plates of our company, and feature high density, no crack and sand hole inside, bright surfaces, uniform color and luster as well as accurate dimensions.
Small tungsten rotary pressing targets are processed by high-quality bars, and feature accurate dimensions, smooth surface, high purity, etc.
Tungsten rotating targets of the conventional size are produced by a hot isostatic pressing process, and feature high density (19.25 g/cm3), fine grains and good molding.
Conventional density: 19g/cm³~19.2g/cm³;
Special process density: more than 19.25g/cm³.
The tungsten targets have the following parameters:
