RUBIG ALUMINUM Treatments

If you are looking for aluminum components with low distortion and low residual stress, choose ALU heat treatments from RUBIG. RUBIG cu­stomers in the automotive and other industries benefit from short pro­cessing times at premium quality.

During heat treatments, a thermal impact is applied in order to posit­ively affect the material charact­eristics of aluminum. The aluminum atoms are arranged in a crystal lattice and contain im­per­fections which increase the strength of the aluminum. The amount of the imperfections contained in the lattice is tempera­ture-dependent. The higher the temperature increas­es, the more imperfections occur and the more moveable the atoms which start to move become. This is called diff­usion and forms the foun­dation for all heat treatments. We offer different aluminium states such as T4, T5, T6, T7 with different quen­ching options (e.g. air quen­ching, polymer quenching, water quen­ching).

Benefits:

• Improves strength
• Avoids deformation
• Dimensional stability
• Improves cold deformation
• Increases toughness

• Heat treatment for wrought alloys
• Heat treatment for casting alloys
• Solution annealing with air qu­enching
• Artificial aging    
• T4: Solution annealed and cold precipitated (Al-Cu-Mg pref­erred)
• T5: Quenched from warm forming temperature and warm precip­itated
• T6: Solution annealed and warm precipitated (Al-Mg-Si alloys preferred)
• T6: Air quenching
• T6: Water quenching
• T6: Polymeric queniching
• T7: Solution annealed and overcured (warm precipitated)
