Vacuum brazed is a process that uses high temperature and low pressure in a vacuum environment to braze. In the vacuum environment, due to the low pressure, the gas will not cause oxidation, hydrogenation or nitriding reactions, so it can be welded with high melting point and difficult to process materials, such as alloy steel, tungsten, molybdenum and so on.

Vacuum brazing, because it does not use flux, significantly improves the corrosion resistance of the product, eliminates all kinds of pollution and pollution-free treatment equipment costs, and has good safety production conditions.
