Tungsten Evaporation Boats

Professionally Customized Tungsten Boats Aid Thin Film Deposition

In the field of vacuum coating and thin film deposition, tungsten boats are used as key consumables, and their performance has a direct impact on the quality and productivity of the films. We are committed to providing customers with high-quality and high-performance tungsten boat products, which are carefully manufactured with high-quality tungsten materials to meet your needs in various evaporation processes. If you are looking for evaporation boats with high temperature resistance, corrosion resistance and good thermal conductivity, then our tungsten boats will be your ideal choice.

Tungsten boats, also known as tungsten evaporation boats, take advantage of the excellent properties of tungsten metal itself, enabling them to work stably and reliably in high vacuum and high temperature environments. The high melting point of tungsten (3410℃) ensures that the tungsten boat is not easy to be deformed and melted during the high temperature evaporation process, which effectively prolongs its service life. At the same time, tungsten boat also has good corrosion resistance, can resist the erosion of a variety of molten metals and compounds, so it is widely used in the evaporation of various materials.

Advantages of our Tungsten Evaporation Boats:

Excellent high temperature resistance: Made of high-purity tungsten material, ensuring structural stability during high temperature evaporation process.

Excellent corrosion resistance: able to work stably for a long time in various corrosive environments.

Good thermal conductivity: helps to quickly and uniformly heat the evaporation material, improving evaporation efficiency.

Multiple specifications to choose from: We offer tungsten boats in various shapes and sizes, including groove, box, dot, etc., to meet the needs of different evaporation materials and processes.

Customizable service: Based on specific customer requirements, we can provide customized services for tungsten boats, including adjustments to special shapes, sizes, and material purity.

Tungsten Boats Usages:

Vacuum Coating: As an important part of resistance evaporation or electron beam evaporation, it is used to evaporate metals (such as aluminum, gold, silver, etc.), alloys and compounds.

Thin film deposition: applied to thin film preparation for semiconductors, displays, solar cells and other fields.

Metal Evaporation: Used for the evaporation and purification of various metal materials.

Compound evaporation: applied to the evaporation coating process of specific compounds.

Scientific research experiment: used as evaporation source container in the field of material science, physics and so on.
