Aluminum Annealing Furnaces

sciprotec aluminum annealing furnaces for universal use are designed for the entire range of aluminum annealing processes (DIN EN 515 >> T1-T9). A flexible and precise process definition is required to carry out various annealing processes. The end result is a product with maximum material quality.

The Benefits:

  • The modular design allows for a practice-oriented adaptation to the design and process specifications
  • Batch assignment using barcodes or an alphanumeric keyboard
  • Unmanned shifts thanks to complete automation

The idea is to have you invest in the material quality of your products and in the flexibility of your production processes at the same time. Ideally, this will achieve a profitable value creation with a comparatively low investment.

The Possibilities:

Recovery Annealing

After chipless cold forming, further forming is possible. Partial reduction of increased strength values. Even semi-hard states can be reached.

  1. Heating up to temperatures of 10…30 K below the crystallization point.
  2. Maintaining the annealing temperature (150…270°C / 302…518°F) for several hours
  3. Cooling down in air or water.

Stress Relief Annealing

After chip-producing and chipless machining, the thermal stress is relieved in this process.

  1. Heating up to temperatures of 10…30 K below the crystallization point
  2. Maintaining the annealing temperature (150…270°C / 302…518°F) for several hours
  3. Cooling down in air or water

Soft Annealing (Recrystallization Annealing)

Elimination of occurring hardening effects, for example, with heat-treatable alloys. Restoration of the form changeability after chip-producing and chipless machining.

  1. Rapid heating to the soft annealing temperature
  2. Maintaining the annealing temperature for several hours
  3. Slow Cool-Down

Homogenizing Annealing

Elimination of crystallization and separation of secondary phases.

  1. Rapid heating to the annealing temperature
  2. Maintaining the annealing temperature for several hours
  3. Slow Cool-Down

Stabilizing Annealing

The dimensional stability of parts which are subject to thermal stress is provided and changes in volume are prevented. (automotive pistons and precision parts)

  1. Rapid heating to the annealing temperature
  2. Maintaining a temperature of 200…300°C (392…572°F) for several hours
  3. Slow Cool-Down

Age Hardening (Natural and Artificial Aging)

Increasing the hardness, tensile and elastic limit (yield strength) of the respective alloy.

  1. Solution annealing directly above the saturation line
  2. Quenching to room temperature (in water)
