Product Description
Snmtco is the leading manufacturer of powder-metallurgically processed refractory and special metals. Based on our core competences in the areas of high performance materials, emerging applications and technologies, we have been manufacturing products and components made from molybdenum, tungsten, tantalum, niobium, chromium and their alloys for more than 15 years.
Refractory metals have various beneficial properties for use in high-temperature processing equipment: high melting point and correspondingly low vapour pressure, low thermal expansion and heat capacity as well as excellent high temperature strength and creep resistance. Through the development of special high performance alloys based on Mo and W (such as TZM, MLR, WVM, etc.) Snmtco has succeeded in significantly improving the microstructural stability and creep strength in comparison to the pure metals. vacuum furnace hot zones and engineered components and offers the most extensive range of high temperature products.
Snmtco always has a comprehensive range of standard components and mill products in stock, deliveries can be made in a few days. Various material grades based on Mo, W and Ta are available.

Snmtco supplies the whole spectrum regarding:
Hot Zones for High Temperature Furnaces
- Materials: Mo, W, Ta, Nb and their alloys
- Shielding/insulation: hybrid hot zones with graphite or ceramic fibre insulation
- Dimensions: hot zones ranging from very small to extremely large
- Design: round, rectangular, vertical, horizontal or special types
- Replacement of graphite with metallic hot zones (usually without needing to change the transformers)
- TIG welded stainless steel structure for support frame and plenum
- ML for components subjected to extreme thermal and mechanical load, such as heating elements, element supports, hot face and gas nozzles
- Optimum choice of the type of heating element for the given application (ribbon, sheet, wire, rod, stranded wire, mesh)
- Double V-groove design and free flowing support for wide ribbon heating elements
- Radiation shielding design guarantees low energy consumption over long-term operation
- U-rails (ML or TZM) replacing standard rails in hearth design for minimum material usage and easy sliding of the workpiece during thermal expansion
