MOLYBDENUM MILL PRODUCTS
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.
At H.C. Starck, we know that assuring product quality contributes to the success of our customers. Therefore, each step in our production cycle is monitored and our quality programs ensure the manufacture of consistent and high-quality products.
H.C. Starck has a team of highly qualified technical experts who have material knowledge and application expertise, and they ensure that our products and processes are developed upon customers' demands. All our plants are ISO 9001 certified and we comply with all customer approval processes.
For those customers who are striving to meet goals of six sigma, molybdenum is often the best choice for demanding applications. If you are interested in controlling your quality and defects, expanding your process capability, minimizing your process variation and ensuring a stable operation, tantalum is a clear choice. Because of its purity, inertness, toughness, reliability and robustness in a variety of environments, tantalum has been the leading choice of customers who are serious about the concepts of six sigma.
