H.C. Starck offers molybdenum Pellets as a consolidated form providing a particularly effective means of making molybdenum alloy additives. The molybdenum pellets are vacuum grade pressed and sintered with a molybdenum content of 99.8 % minimum.

Pellets are sintered in hydrogen and have extremely low gas content, which keeps degassing during vacuum melting to an absolute minimum. Pellets are pressed and sintered to withstand rigorous handling. In addition, they are sufficiently small enough to dissolve rapidly and yet dense enough to settle into the molten metal bath.

Vacuum melt 99.8 % and air melt 99 % grade pellets are available.

We produce alloy additives from molybdenum, tungsten, tantalum and niobium refractory metals which are derived from our production processes. We use high-quality materials with some of the highest purity levels.

Superalloy materials obtain many of their high temperature strength and corrosion resistance through the use of refractory metal alloying.

H.C. Starck offers all of the major refractory metals to the specialty alloy producers as alloying agents. Special low gas content is available which keeps out-gassing to a minimum. Various grades are available to meet customer requirements.

Products are offered in all forms as melt additives:

  • Chips
  • Turnings
  • Trimmings
