TANTALUM SHEET, PLATE, ROUND DISK AND FOIL
Customers transform our tantalum plate into products for military, chemical processing, and other anti-corrosion type applications.
Both tantalum sheet and plate are used by customers in the manufacturer of components for anticorrosion equipment. Round discs cut from tantalum plate are employed to repair and reinforcement work in anti-corrosion equipment.
Because of their strength and workability, very thin sheets of tantalum can be clad to other surfaces, providing superior corrosion protection and cost effectiveness.
Our tantalum sheet and plate are supplied with a cold-rolled and chemically cleaned surface. The sheet and plate may be locally conditioned to remove defects, provided that thickness tolerance is maintained.
Depending on your specifications and needs, all of our tantalum sheet, plate, and foil are visually inspected for slivers, laminations, excessive roll marks and handling scratches.
ULTRA76 Ta alloys offer higher corrosion resistance in most environments generating value added by extending product life time, reducing material thickness and improving processes throughput.

- Constant surface finish (Ra<0.8 micrometers)
- Material only from non-conflict sources, H.C. Starck Solutions is EICC certified

TUNGSTEN PLATE, SHEET, AND FOIL
Tungsten mill products available from H.C. Starck Solutions include plate, sheet, and foil with many options on width, length and thickness. Pure Tungsten flat rolled products are fabricated from pressed and sintered powder metallurgy ingot and are rolled to a wide range of plate, sheet, and foil thicknesses.

Tungsten discs, washers and squares for power semiconductors
Tungsten is widely used as contact materials in silicon controlled rectifiers diodes, transistors and thyristors (GTO’S). Other than in specialist applications, molybdenum is now accepted as the first choice mounting material for power semiconductor devices due to its significantly lower cost and weight.
The fact that both materials have a similar coefficient of expansion to silicon combined with high thermal conductivity makes them an ideal choice, especially in large area power devices where considerable heat is generated. Further applications include the use of molybdenum and tungsten as heat sink bases in IC’S, LSI’S and hybrid circuits.

MOLYBDENUM PLATE, SHEET AND FOIL
Vacuum Arc-Cast Molybdenum Mill Products
The VAC method of consolidation is unique to H.C. Starck Solutions. Materials made by this process is available exclusively from H.C. Starck Solutions 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 Solutions 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.
