Annealing of a metal alloy is a heat treatment which consists in heating to a usually lower than the melting temperature, followed by the appropriate duration of stay and usually by a slow cooling in the furnace.
The Galli models, from low furnace at higher temperatures + 260 ° C, + 300 ° C, + 500 ° C, + 800 ° C, + 1100 ° C + 1200 ° C + 1400 ° C and 1800 ° C they offer solutions to the annealing or annealing processes.
This process is used mainly on steels, copper but also aluminum and its alloys to prepare them for subsequent processing steps, making the sweeter and more homogeneous material.
But there are also applications of electronic microcircuits, when you have to reduce tensions within the crystal lattice of the silicon.
The Annealing alters the microstructure of the material, changing its properties such as flexibility and hardness. Typical result is the removal of the defects of the crystalline structure.
