Why choose Induction Brazing?

First of all, what is induction brazing? 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. In induction brazing, usually ferrous materials are heated rapidly from the electromagnetic field that is created by the alternating current from an induction coil.
For filler metals: Silver is frequently used for induction brazing because of its low melting point. Silver-copper eutectic brazes have melting temperatures between 1100°F and 1650°F. Aluminum braze, the least common, has a melting temperature of 1050°F to 1140°F. Copper braze, the least expensive, has a melting temperature of 1300°F to 2150°F.
The filler can be manually applied but because of the more common semiautomatic production a preloaded joint is more commonly used to speed the operation and help to keep a more uniform bond.


Therefore, induction heating technology is steadily displacing open flames and ovens as the preferred heat source in brazing. There are briefly seven key reasons which can explain this growing popularity for induction brazing. Now let’s start it.

  1. Speedier solution
Induction heating/brazing transfers more energy per square millimeter than an open flame. Put simply, induction can braze more parts per hour than alternative processes.

  2. Quicker throughput
Induction is ideal for in-line integration. Batches of parts no longer have to be taken aside or sent out for brazing. Electronic controls and customized coils let us integrate the brazing process into seamless production processes.

  3. Consistent performance
Induction heating/brazing is controllable and repeatable. Enter your desired process parameters into the induction equipment, and it will repeat heating cycles with only negligible deviations.

  4. Unique controllability
Induction lets operators view the brazing process, something that is difficult with flames. This precise heating can minimize the risk of overheating, which causes weak joints.

  5. More productive environment
Open flames create uncomfortable working environments. Operator morale and productivity suffer as a result. Induction is silent. And there is virtually no increase in ambient temperature.

  6. Put your space to work
Induction brazing equipment has a small footprint. Induction stations slot easily into production cells and existing layouts. And our compact, mobile systems let you work on hard-to-access parts.

  7. No-contact process
Induction produces heat within the base metals — and nowhere else. It’s a no-contact process; the base metals never come into contact with flames. This protects the base metals from warping, which in turn increases yield and product quality.

There are also other usages for induction heating, such as induction melting, induction welding, induction forging, induction hardening and etc. For learning more information about it, you can visit our website or just send an email to us. Thank you.
