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.

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.

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.

Technical ceramics may be generated under pressurized conditions in an inert environment to ensure full densification and homogeneity of the green body, while sintering of most metallic powders can typically be conducted under atmospheric pressures with a catalytic gas. H.C. Starck Solutions specializes in the fabrication of sturdy sintering trays suitable for various furnace architectures.

With almost 100 years’ experience in the supply of superb, pure and alloyed refractory materials, H.C. Starck Solutions offers high-performance sintering trays suitable for high-temperature material processing in a range of conditions.

Refractory Sintering Trays

Sintering is conducted to fuse fine particles of a material into a singular solid mass by elevating the temperature of the powder to the point at which atoms begin to diffuse across particle boundaries. This causes fusion without causing the material to melt. Refractory metals and alloys are ideal for manufacturing sintering trays due to their exceptional thermodynamic properties.

H.C. Starck Solutions fabricates sintering trays to custom geometries, using a range of high-performance refractory materials. These include:

  • Pure molybdenum (Mo) and electron beam melted (EBM) molybdenum, alongside its alloys molybdenum-lanthanum (MoLa) and titanium-zirconium-molybdenum (TZM).
  • Tantalum (Ta) in both standard and EBM formats.
  • Tungsten (W).

These materials can be manipulated to demonstrate superior mechanical properties at elevated temperatures, guaranteeing high-purity conditions for chemically-sensitive sintering operations. H.C. Starck Solutions can provide sintering trays using each of these high-performance refractories for high-temperature furnaces operating in vacuum, reducing, or inert atmospheric conditions.

Heating Elements

H.C. Starck Solutions molybdenum is a superior, pure and alloyed refractory material for heat treating medical, aerospace, defense and automotive products in high temperature furnaces that include medical devices, aircraft and aerospace components, nuclear fuel pellet production, and high pulse magnet research applications. Our innovative materials improve cycle-time and maintain temperature uniformity with no carbon contamination, less rejection of components, better handling and reduced production cost compared to graphite and ceramics for a wide spectrum of metal injection molding applications.

For higher temperature heat treating applications such as hardening or brazing, molybdenum is the preferred heating element material. For specialized heat-treating applications above 1,482 °C (2,700 °F), refractory metals such as molybdenum, tantalum or tungsten are good choices. Other processes such as low pressure vacuum carburizing use graphite or silicon carbide elements.

Almost all high-temperature vacuum furnaces are electrically heated. Resistance heating elements are constructed from refractory metals in a variety of styles. Today all high-tech metallurgy technology operates in vacuum atmosphere with high temperatures from 1,150 oC up to 2,800 oC.

Recrystallization and High-Temperature Warpage Resistance

Molybdenum-lanthana (MoLa) alloys are one type of oxide-dispersion strengthened (ODS) molybdenum containing molybdenum and a very fine array of lanthanum trioxide particles. This combination creates extraordinary characteristics of the material, which demonstrate resistance to recrystallization as well as high-temperature warpage. Molybdenum-lanthana is an ideal material for applications requiring dimensional stability and strength at temperatures above the capabilities of either pure molybdenum or molybdenum TZM alloy.

H.C. Starck Solutions manufactures MoLa alloys in three levels of doping with lanthanum trioxide: 0.3 weight %, 0.6 weight % and 1.1 weight %. The trioxide particles stabilize the grain structure of the material creating very beneficial high temperature performance. The unique H.C. Starck Solutions doping process of introducing the oxide particles to the molybdenum matrix is key to the excellent properties obtained, and differentiates H.C. Starck Solutions from other manufacturers of similar materials. In addition, the doping process maximizes the homogeneity of the lanthanum oxide dispersed in the molybdenum matrix.

Benefits of H.C. Starck Solutions MoLa Alloys

MoLa alloys have great formability at all grade levels when compared to pure molybdenum in the same condition. Pure molybdenum recrystallizes at approximately 1,200 °C and becomes very brittle with less than 1 % elongation, which makes it not formable in this condition.

MoLa alloys in plate and sheet forms perform better than pure molybdenum and TZM for high temperature applications. That is above 1,100 °C for molybdenum and above 1,500 °C for TZM. The maximum advisable temperature for MoLa is 1,900 °C, due to the release of lanthana particles from the surface at higher than 1,900 °C temperature.

The “best value” MoLa alloy is the one containing 0.6 wt % lanthana. It exhibits the best combination of properties. Low lanthana MoLa alloy is an equivalent substitute for pure Mo in the temperature range of 1,100 °C – 1,900 °C. The advantages of high lanthana MoLa, like superior creep resistance, are only realized, if the material is recrystallized prior to use at high temperatures.

Titanium-Zirconium-Molybdenum (TZM) Alloy

H.C. Starck’s molybdenum TZM alloy (0.50 Ti, 0.08 Zr, Bal Mo) is consolidated by either the powder metallurgy or our unique vacuum arc-casting processes. The titanium and zirconium carbides increase strength and creep resistance at elevated temperatures. The use of TZM also enables higher service temperatures without loss of strength in comparison to pure molybdenum.

Molybdenum-Hafnium-Carbide (MHC) Alloy

Our molybdenum MHC alloy contains molybdenum and hafnium carbide, which is consolidated by our exclusive powder metallurgy process. The high recrystallization temperature, high strength, low thermal expansion, and high thermal conductivity of this alloy makes it ideally suited for die applications.
