If you’re wanting to know more about vacuum brazing, you’ve come to the right place. At Fusion Europe, we pride ourselves on being a leading manufacturer of brazing paste, soldering paste and brazing powders. So, it’s safe to say that we know all there is to know about the process. In this blog, we’ve taken a look at the ins and outs of vacuum brazing, looking at the benefits, applications and how our expert team can help.

 

 

What is Vacuum Brazing?

There are a few different ways to join metal components together, one of which is vacuum brazing. It’s a technique that uses a brazing filler metal in solid or paste form, which is placed between two components, and then heated. The brazing filler metal always has a lower melting point than the parent components so melts first and fills the gaps between the two parent components. On cooling, the brazing filler metal solidifies and forms a strong intermetallic joint between the two parts being joined.

The vacuum brazing process happens within a vacuum furnace, which creates a controlled environment that stops oxidation and contamination. The absence of oxygen ensures that the joints are clean, strong and free from any impurities that could impact the strength of the bond.

 

 

The Key Benefits of Vacuum Brazing

There are a whole host of benefits that come with vacuum brazing, which is why it’s often favoured over many other, more traditional metal joining methods.

 

• High Quality Joining – As vacuum brazing uses a controlled environment that prevents oxidation and contamination, high quality, clean and strong joints can be achieved. This is particularly beneficial if you’re working with materials that are sensitive to oxidation.

 

• Minimal Material Stress and Distortions – As vacuum brazing uses specific heating and cooling rates, the risk of the material being put under thermal stress and distortion is low. This helps to preserve the shape and dimensions of the components, preventing any damage to them during the vacuum brazing process.

 

• Join Different Materials Together – With vacuum brazing, you can join different materials together, meaning that two dissimilar metals can be joined securely using the technique. It’s also possible to use vacuum brazing on combinations of metals and ceramics, which can be difficult to join using other methods.

 

• No Risk of Flux Entrapment – Flux entrapment happens when surplus flux gets stuck in a braze joint. As vacuum brazing doesn’t require any flux, there’s no risk of this happening. Flux entrapment can occur during other brazing methods, and it needs to be cleaned after the brazing process is complete.

 

• It’s Cost-Effective and Efficient – Though vacuum brazing does require specialist equipment, it can actually be a cost-effective metal joining method. This is due to reduced material waste and its energy efficiency, and that there’s no post-braze cleaning required. This also speeds up the joining process.

 

 

When is Vacuum Brazing Used?

Vacuum brazing is a versatile joining technique, which is why you’ll find it being used for a wide range of applications, including:

 

• Aerospace – Vacuum brazing is used in the manufacturing of lightweight ,yet durable components, where a reliable and strong join is critical.

 

• Automotive – It’s also used in the production of automotive parts, including fuel injections and transmission components. Vacuum brazing ensures that durable and precise joints are guaranteed.

 

• Medical Devices – Vacuum brazing is used to assemble medical devices and implants, where joint integrity is key. It also helps to make sure that joints are biocompatible, making them safer to use in the medical field.
