NIOBIUM ROD

H.C. Starck Solutions offers NRC® niobium metal produced from electron beam melted ingots. Grain Stabilized Niobium (GSNb) is made by EB and VAR melting. Both materials are malleable, weldable, machineable and formable. GSNb is used in applications where a consistently finer grain size is required.

GSNb is a patent pending single-phase micro-alloy that has a grain size of approximately 2 ASTM numbers finer than standard commercial grade niobium.

Niobium is used in the manufacture of products for diverse applications.

  • Synthetic diamonds
  • Sputtering targets for fiber optic applications or architectural glass
  • Nickel based superalloys; and alloyed with titanium or tin
  • Superconductors
  • Nuclear reactors it has low thermal neutron cross section and superior corrosion resistance
  • High temperature vacuum furnaces, where it is an excellent getter
  • Sodium vapor lamps, where it is resistant to attack by the molten alkali

Niobium rod is worked cold from ingot to final diameter. Forging, rolling, swaging, and drawing are used singularly or in combination to reach the desired size. Proprietary techniques have been developed by H.C. Starck Solutions to overcome the metal’s extremely high-galling tendencies.

Rod is generally supplied with a forged surface above 1-3/8″ diameter, and a swaged or drawn finish in smaller diameters. Rod, preferably un-annealed, may be centerless ground to improve diameter tolerances. The minimum diameter for centerless grinding is .125″. Rod to a maximum of 1/4″ and wire may be supplied in coils or straightened and cut to length.

TANTALUM ROD,  WIRE, COIL

A favorite with chemical processing applications that require anti-corrosion characteristics is tantalum rod including the manufacturer of components for anticorrosion equipment.

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.

Work-ability 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.

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 Solutions 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.

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.

H.C. Starck Solutions has emerged as one of the leading suppliers of advanced shielding parts for radiation and heat management, and superconductivity applications.

Shielding Parts for High-Technology Applications

The density of a material is an essential factor in its radiation absorption properties. Heavier metals like tantalum (with a density of ~16.6 g/cm3) and tungsten (~19.3g/cm3) are more effective at absorbing radiation across the full spectrum – including X-rays and infrared (IR) waves – than conventional structural materials. Yet, the inherent properties of these metals make them very difficult to fabricate into finished components with the tight tolerances required of high-technology applications.

H.C. Starck Solutions has over 20 years’ experience in the field of manufacturing intricate components using high-performance refractory metals for the medical sector. Specializing in the generation of fabricated shielding parts for medical and industrial applications, H.C. Starck Solutions offers tailored radiation management solutions comprised of some of the heaviest metals on earth. These capabilities are buoyed by expertise in the fields of CNC grinding, milling, and lathe turning for numerous refractory material types. Final quality control processes guarantee that shielding parts are delivered within tight tolerances to customer specifications, with high capability inspection equipment ensuring highly uniform topographies with approximate resolutions of 0.1 – 1 micrometer (μm).

H.C. Starck Solutions shielding parts made using tantalum, tungsten, and their alloys have already provided appreciable returns on investment (ROIs) to customers in demanding industrial processing applications, advanced medical technology sectors, and cutting-edge superconductivity markets.
