Induction Brazing

Many methods of heating and shaping metals have been developed over the centuries. Human beings have even modified the properties of metals by adding alloys to increase hardness, electrical conductivity, or resistance to corrosion. Brazing, soldering, and welding are three of the most common processes.

In brazing, metal parts are joined using other metals having a high melting point, such as copper, silver, and aluminum alloys. Brazing differs from soldering by using higher temperatures. Both induction brazing and induction soldering exploit the advantages of induction heating, such as pinpoint heating of a part. Welding, by contrast, involves the melting of portions of the actual metal pieces to be joined.

Induction Brazing Eliminates Potential Problems

By producing rapid, localized heat, induction brazing can prevent the distortion which is always a potential problem in other high-temperature heat treating methods. Induction brazing also minimizes oxidation, again because of the speed of heat inducement. Finally, the method produces a clean, brazed joint and so, reduces cleaning after the part is treated.

Alloys

An alloy consists of a metal fused with another metal or metals, or with non-metals. The value of alloys in metallurgy is their ability to produce the desired characteristics in a substance. For example, brass and bronze are often alloyed with copper to increase its hardness. Pure gold and silver are quite soft, so to render them more practical for making jewelry, they are alloyed with each other or with other metals.
