SMI Ltd. offers a wide-array of fabricated tungsten and molybdenum products, including plates, sheets, rods and wire. Our engineers have also developed doped tungsten products that enhance sag and corrosion resistance. These are used in halogen lamp filaments, short arc lamps, evaporation coils and furnace elements. Tungsten-Rhenium thermocouple assemblies produced and developed by SMI Ltd.’s engineers permit ultra-high temperature measurements far in excess of conventional ISA standard letter designated thermocouples. Please also contact us regarding tungsten evaporation.
