How to Braze Aluminum

Applications for induction heating

In the 1920’s, there was a huge shift in the manufacturing industry that has forever changed the world of industrial work. While this may not seem like a huge shift to anyone living in modern day society, it was a humungous deal to the people of this time. Within this time frame, the basic principles of induction heating have been applied to manufacturing.

Heating is one of the easiest methods of building and repairing items. Understand that this is exactly how to braze aluminum. It is something that usually is done by people who understand induction melting, soldering heat, and how to handle a concentration of high temperatures in general.

Materials with high permeability are easier to heat through induction heating. Iron and its alloys respond well to induction heating due to their ferromagnetic nature. While this all seems random it is important to know when trying to understand how to braze aluminum.

The steps in how to braze aluminum are quite simple. First and foremost, make sure you have the right equipment. This stars with your gear, ensuring that it is heat resistant and safe against chemicals.

An induction heater is usually going to be made up of three different parts which include the work coil, the work head, and the power unit. Induction heating is used in processes where temperatures are as low as 212 degrees Fahrenheit and as high as 5432 degrees Fahrenheit. These are facts you should know when you want to know how to braze aluminum.

It is important to use the brazing materials to then connect the two sides of the aluminum where the crack is. Once this is done, you will begin to utilize the heat. Induction brazing is a process in which two or more materials are joined together by a filler metal that has a lower melting point than the base materials using induction heating.

The heat is utilized in the induction melting aluminum. This works to seal together the two sides firmly so that they will not split or break away from one another. Silver is often used for induction brazing because of its low melting point. For instance, silver-copper eutectic brazes have melting temperatures between 1100 and 1650 degrees Fahrenheit.

Brazing aluminum is not easy and if you are not 100% clear on how to braze aluminum, maybe you should reach out to an expert. The Curie point is the temperature at which certain magnetic materials undergo a sharp change in their magnetic properties. The Curie point of iron is 1,418 degrees Fahrenheit.

The top three benefits of induction hardening are fast heating cycles, accurate heating patterns and cores that remain relatively cold and stable. There are two methods of heating when using induction: eddy current heating and hysteretic heating. The efficiency of an induction heating system for a specific application depends on four factors: the characteristics of the part itself, the design of the inductor, the capacity of the power supply, and the amount of temperature change required for the application.

In Conclusion

Every single year there are plenty of people that hire experts who know how to braze aluminum. While this process is not complex, it is also not easy. This is mainly due to the fact that this process involves high temperatures that are pretty dangerous.
