MOLYBDENUM PRESSED AND SINTERED BILLETS
The VAC method of consolidation is unique to H.C. Starck. Materials made by this process is available exclusively from H.C. Starck and yields a homogeneous product which is very low in residual elements, provides better strength at elevated temperatures and exhibits excellent workability, weld-ability and good machining characteristics.
In the vacuum arc-casting process, 99.95% pure molybdenum powder, ultra-pure molybdenum powder or one of our molybdenum-base alloys is pressed, sintered, and melted (all under vacuum) to produce a casting weighing up to one ton. This arc-casting is then further worked by extrusion followed by forging or rolling.
Where highest purity, maximum toughness, and ductility at low temperatures are required, arc-cast molybdenum mill products are available in a special low-carbon grade. This material is 99.97% pure molybdenum and contains a maximum of .010% residual carbon, compared to the nominal .030% maximum carbon content of normal arc-cast molybdenum.
Workability and machinability are also superior with this special product.
H.C. Starck produces a wide range of molybdenum and molybdenum alloy mill products using two primary consolidation methods; vacuum arc-casting (AC) and powder metallurgy (PM). The availability of products from both of these established processes gives users many options in selecting a material to satisfy their specific application requirements. Mill products available from either process include forging billets, bar, rod, sheet, plate and foil.
