Molybdenum Discs and Squares

Molybdenum discs and squares are widely used as contact materials in silicon controlled rectifier diodes, transistors and thyristors. Molybdenum has similar coefficients of thermal expansion (CTE) to silicon combined with moderate thermal conductivity, and are therefore suitable for large area power devices where considerable heat is generated.

Further applications include the use of molybdenum as heat sink bases in IC’s, LSI’s and hybrid circuits.

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.

Heat Sinks

ADVANTAGES

High-temperature heat sinks are innovative devices that regulate the temperature of electronic systems. Low-power electronics typically use common and cost-efficient alloys that demonstrate good thermal conductivity. Aluminum (Al) and copper (Cu) are two of the most ubiquitous metals used in heat sink applications. They are ideal for their lightweight properties and high rates of thermal conductivity, but they cannot reliably diffuse the volumes of heat generated by high-power electronic devices.

Composite alloys using a refractory metal bonded with copper exploit the outstanding thermomechanical properties of both materials, enabling the fabrication of high-temperature heat sinks for advanced electronics markets. H.C. Starck Solutions specializes in the fabrication of heat sinks with finely-tailored material ratios; providing solutions to demanding applications in the electronics industry.

Refractory Composites for Heat Sinks

H.C. Starck Solutions has decades of experience in the development of advanced materials for demanding thermal management applications. In tandem with the challenging dual trends of device miniaturization and increased functionality, the electronics industry consistently requires innovation when it comes to cooling. Materials must dissipate heat faster and more efficiently with a smaller component footprint.

Molybdenum- (Mo) and tungsten- (W) copper alloys rise to the challenges of thermal management in advanced electronics applications. H.C. Starck Solutions offers both molybdenum and tungsten composites with tunable ratios of refractory to copper to provide the optimal intersection between low coefficients of thermal expansion (CTE) and thermal conductivity. These are essential properties for regulating the heat generated from dense, high-performance electronic devices.  

H.C. Starck Solutions offers low-density molybdenum-copper (MoCu) for heat sink applications, using a molybdenum skeleton infiltrated with copper at ratios of approximately 70:30 (Mo:Cu). This low-density composite is suitable for the most demanding electronics applications and is approved for military and aerospace applications. Tungsten-copper (WCu) composites are also available, with similarly high thermal properties, exceptional machinability, and varying ratios of tungsten to copper available on request.

Collimators/Anti scatter grids

ADVANTAGES

Collimators, or anti-scatter grids, are critical components for radiation management in computerized tomography (CT) scanning. They are typically manufactured using dense refractory metals and alloys such as tungsten (W) and tungsten heavy alloy (WHA) due to the materials’ superb attenuation characteristics for X-radiation – the chief wavelength range used to generate detailed CT scans.

With unmatched experience in the fabrication of high-technology parts using refractory metals and alloys, like tungsten and molybdenum (Mo), H.C. Starck Solutions can reliably produce and supply collimators for radiation management in CT scanners and radiotherapy applications.

Collimators for Radiation Management

Collimators manage radiation by either focusing an X-ray source into a manageable, parallel beam of rays that is directed onto an area of interest, or by absorbing scattered rays before they enter photodetectors. Lead (Pb) and depleted uranium have been used in the past, but tungsten has emerged as the ideal replacement for multi-leaf collimators in radiation therapy beam focusing and detector plates in CT scanners for a number of reasons.

Tungsten is a remarkable metal with a notably high density (~19.3g/cm3), which makes it suited for radiation shielding in complex medical apparatuses. It is widely used in the medical diagnostics market to fabricate collimators for both beam focusing and CT scanner assemblies. The outstanding mechanical properties complicate its workability, however, and the fabrication of multi-leaf tungsten collimators requires significant experience in precision machining and tolerancing of refractory metal parts.  

H.C. Starck Solutions fabricated products and services are routinely supplied as robust solutions for intricate challenges in the medical technology sector. With high capability inspection equipment and unmatched expertise in working dense metals like tungsten, H.C. Starck Solutions has emerged as one of the leading suppliers of collimators for CT scanning and radiotherapy applications. All fabricated components can be rapidly and reliably finished, with a contact-free quality assurance and control process guaranteeing components are form fit with a resolution of approximately 0.1 – 1 micrometer (μm).
