Description

Induction heating is the process of heating electrically conductive materials like metals by electromagnetic induction, through heat transfer passing through an induction coil that creates an electromagnetic field within the coil to melt down steel, copper, brass, graphite, gold, silver, aluminum, and carbide.

What is the principle of induction heating?
Induction heater units incorporate high frequency generators for non-contact heating of metal using electromagnetic induction. When AC is applied to a coil surrounding the work (metal), a magnetic field is generated by the current flowing in the coil, and induced loss (hysteresis loss) is generated causing a heat.
What does annealing do to brass?
Brass Annealing is the process of ‘rejuvenating’ the brass which has the result of prolonging brass life and increasing consistency. It’s basically (and literally) stress relief for your brass.
When should you anneal brass?
Annealing should always be done before resizing. This eliminates spring back, and ensures repeatable and accurate shoulder bumping and neck sizing. Annealing should be done every reload.
