How to Find the Best Induction Furnace
Induction furnaces have maximum temperatures optimized for different types of metal, so a unit capable of melting carbon steel must produce temperatures between 2600F and 2800F. On the other hand, a copper induction furnace generates temperatures up to 2000F, and you can only use it to work with metals with melting points below 2000F.
