The properties of titanium make it an excellent choice of engineering material for a range of applications, from aerospace to chemical processing due to its high relative strength and corrosion resistance properties. These properties can be improved by alloying various elements to enhance specific properties making titanium a truly versatile engineering alloy.
Induction brazing uses the same basic principles as an induction hob you may find in your kitchen or employed in heat-treating steel. The article which follows will look into the benefits and limitations of induction brazing as well as examine the principles and best practices to ensure a sound braze joint.
Like many other innovations in science, the process of active brazing was reportedly discovered by accident. During brazing trials an alloy containing a small amount of zirconium inadvertently flowed onto an alumina fixture during the more commonly used molybdenum manganese metallization method. To the surprise of the engineer, the alloy wet and bonded to the ceramic. The zirconium was acting as the active element which allowed the braze alloy to wet the ceramic. This realisation has changed the way we join ceramics today.
You may instinctively associate VBC with Vacuum Brazing technologies but did you know we also technically support Induction brazing?
Induction brazing is an efficient and clean method of joining metallic and ceramic components which can be carried out in air but there are further benefits to be obtained when brazing in inert or reducing atmospheres.
