Crucibles produced by Achemetal Tungsten & Molybdenum Co., Ltd. include small tungsten crucibles and molybdenum crucibles for turning, plate spinning cruible tungsten crucibles, spinning crucible molybdenum crucibles, vacuum welding tungsten crucibles and molybdenum crucibles, large sintering tungsten crucibles and sintering tungsten-molybdenum alloy crucibles.
Bar turned crucibles are formed by turning high-quality bars of our company, and feature high density, no crack and sand hole inside, bright surfaces, uniform color and luster as well as fine crystal grains.
spinning crucibles are made of high-quality plates through exclusive spinning crucibles equipment of our company. The spinning crucibles of our company feature accurate appearance, uniform thickness transition, smooth surface, high purity, strong creep resistance, etc.
Welded crucibles are formed by welding high-quality tungsten plates and molybdenum plates through sheet metal machining and vacuum welding technologies. The welded crucibles of our company feature good roundness, smooth welding seams, good firmness, no air leakage after pressurization, etc.
Sintered crucibles are made of high-quality tungsten powder and molybdenum powder through strict screening, mixing, blank setting, pressing, powder turning and other processes, with scientific control over sintering temperature gradient and long insulation time. In cooperation with an HIP process, the crucibles can achieve the features of high density, fine crystal grains and good molding.
Conventional density: 18.6g/cm³~18.9g/cm³;
Special process density: more than 19.1g/cm³.
Typical specifications and dimensions of crucibles：
|Bar Turned Crucibles||15~80||15~150||≥3|
|Sintered Crucibles||80~550||50~700||5 or more|
Note: all the specifications can meet the requirements of customers on high accuracy through machining.
