Vacuum brazing is a process of joining metal parts in a vacuum chamber using a filler metal - the brazing alloy.
The method offers significant advantages in terms of the quality of joints and component integrity. With a brazing temperature of 800 – 1200 °C, it produces clean and strong joints that are highly resistant to a wide range of temperatures and conditions.
The level of purity of the atmosphere in a vacuum can be precisely controlled, which results in less residual oxygen contaminating the work piece.
Vacuum brazing produces strong, resistant to corrosion and fatigue, high-quality bonds between metal components.
The vacuum environment of the furnace helps to eliminate any porosity that may be present in the brazing alloy or metal components, which might then affect the strength and reliability of the bond.
The vacuum environment of the furnace prevents the brazing alloy and metal components from oxidizing, which can weaken the bond and affect the performance of the final product.
Vacuum brazing can be applied to join metal components that will be subjected to high temperatures.
The vacuum brazing process is highly precise, which allows for the joining of thin, closely spaced elements.
