Tungsten products can be used for heating elements in vacuum furnaces that exceed the temperatures of molybdenum and tantalum as well as other heater applications. Tungsten has also gained wide acceptance as an essential material in electrical contacts, glass-to-metal seals, supports, and electrodes.

Boats are used for the vacuum evaporation of materials that are in granular or pellet form. They can also be used to evaporate small lengths of wire or to evaporate materials which would not properly "wet" the surface of an evaporation filament. These boats are ideal for use in small evaporation systems, such as bell jars, for experimental and prototype work. Please specify material (tungsten boat, molybdenum boat, or tantalum boat) and thickness (. 005, . 010, 0.15, . 020, or other sizes). All dimensions shown are in inches.
