China W1 pure wolfram tungsten boat for vacuum coating Manufacturer and Supplier

W1 pure wolfram tungsten boat for vacuum coating

Short Description:

W1 pure tungsten boat is often used in vacuum coating process. These boats are designed to contain and transport materials such as metals or other substances in vacuum evaporation systems. Pure tungsten’s high melting point and excellent thermal conductivity make it ideal for this application, as it can withstand high temperatures and provide the uniform heating required to vaporize the material in a vacuum environment.
