Tungsten Filaments and Coils

The tungsten boats, baskets and filaments are manufactured from high grade tungsten. Of all metals in pure form, tungsten has the highest melting point (3422°C / 6192°F), the lowest vapor pressure at temperatures above 1650°C (3000°F) and has the highest tensile strength. Tungsten also has the lowest coefficient of thermal expansion of any pure metal. This combination of properties makes tungsten the ideal material for evaporation sources. During evaporation, it can alloy with some materials such as Al or Au. In this case, another evaporation source material should be used such as alumina coated boats or baskets. Other materials useful for evaporation sources are molybdenum and tantalum. Please see the Deposition Techniques Table for extensive information on vacuum deposition and suitability of evaporation sources.

Tungsten Filament

Tungsten Wire Rod Source

Tungsten rod source with fine tungsten wire. This type of source is designed for applications where a relatively large amount of material needs to be evaporated with a lower power evaporation source. The fine tungsten wire accommodates more molten material than the standard single or three strand evaporation filaments. Suitable for low and medium temperature materials. The rod is 4" (101.6mm) long with a 0.1"(2.5mm) diameter. The 0.020" (0.5mm) diameter wire is wrapped in 8 layers over a 2" (50.8mm) wide length.
Settings: 1.12V/148A/166W for 1500°C
