Tungsten Evaporation Boat

Tungsten boats, also known as evaporated tungsten boats or coated tungsten boats, are formed by high-temperature stamping of tungsten sheets. There are types such as stamping boats and folding boats, which are widely used in the vacuum coating industry and the ship industry for sintering or vacuum annealing in sintering furnaces.

Tungsten boats are widely used in vacuum coating industries such as gold plating, evaporators, imaging tube mirrors, heating containers, electron beam painting, household appliances (shells), mobile phones, toys, and various decorations, as well as in ship industries such as sintering furnaces or vacuum annealing.

In an ideal (vacuum, dry) state, connect wires at both ends of the tungsten boat and apply electricity. Place the low melting point metal in the middle recess and wait for its temperature to rise below 2000 degrees. The metal will evaporate into gas and be deposited on the surface of the workpiece.

High-temperature performance: Tungsten has a high melting point, so the evaporation boat stays stable during high-temperature evaporation and won't deform or melt easily.

Corrosion resistance: The evaporation boat resists corrosion well and can handle many molten metals and compounds.

Thermal conductivity: It conducts heat effectively, ensuring quick and even heating of the evaporation material for better efficiency.

Customizability: We offer tailored solutions, including special shapes, sizes, and material purity adjustments, to meet specific customer needs.

Vacuum Coating: Used as a key component in resistance or electron beam evaporation to vaporize metals (like aluminum, gold, silver), alloys, and compounds.

Thin Film Deposition: Applied in semiconductor, display, and solar cell industries for thin film production.

Metal Evaporation: Used for vaporizing and purifying various metal materials.

Optical Coatings: Helps produce high-quality optical components, such as mirror coatings and anti-reflective coatings.

Electronics Manufacturing: Essential in making electronic parts like solar cells, LEDs, and LCD displays.

Aerospace & Defense: Used in high-performance optical and thermal barrier coating technologies.
