What are the differences between induction furnaces and resistance furnaces

First, look at the heating principle:

Induction furnaces use electromagnetic induction to make metal heat itself. They can only heat metal.

Resistance furnaces generate heat through resistance elements and transfer it. They can heat metal and non-metal.

About heating speed:

Induction furnaces heat fast, and heat immediately when turned on.

Resistance furnaces heat slowly, needing some patience to wait. But they can adjust temperature accurately.

About budget and output:

Induction furnaces usually have lower unit price and small output.

Resistance furnaces have higher unit price and large output threshold.
