Annealing is a process where the parts are heated up and then they are cooled slowly to obtain a softer structure of the part and to optimize material structure for subsequent forming steps.
Parts that are annealed will have a change on the physical and sometimes chemical properties of a material to increase its ductility and reduce its hardness, making it more workable. Also some magnetic properties may be changed by annealing the alloy in a controlled atmosphere.
The annealing is performed at high temperatures in a controlled atmosphere with an endothermic gas (Nitrogen) to avoid oxidation of the metal’s surface and scale. Parts may get a bright color with this process.
Benefits of this process are:
- Superior quality with homogeneity on the parts
- Reduction of heat treatment distortion and/or variation of distortion
- Heating and cooling rates are adjustable
- Green process, no emissions or need to dispose chemicals
- Clean, non-toxic working conditions
- Reproducible results
- Clean and dry parts
- State of the art, up to date technology
- In accomplishment with CQI 9.
Some components that are annealed are solenoid housings, sensor cases, and a diverse variety of components that are made of steel, copper, aluminum, among others.
