The main processes in the metal heat treatment industry include annealing, tempering and quenching, etc., which are mainly used to heat treat various alloys, non-ferrous metals, magnetic materials, etc. Brother Furnace's vacuum furnaces enable metal parts to be heated and cooled at high temperatures by providing precise temperature control and atmosphere regulation. These processes adjust the metal's microstructure and mechanical properties to achieve the desired hardness, strength and corrosion resistance.
