Customer testimonials

Damien PIGNOL

Lisi Aerospace - Methods and aeronautical supply chain engineer

"Customers impose a series of very strict technical standards, particularly with regard to mechanics, to which parts must strictly conform thanks to rigorous heat treatment procedures.
This involves careful monitoring of furnaces, qualification of processes and obtaining essential quality certifications. However, all these skills are not always available in-house, which explains the need to call on experts such as Thermi-Garonne to carry out these treatments, especially when it comes to mass production of highly specialized industrial parts."

    Our FAQs

    Which sites are certified for aeronautics?

    THERMILYON Group sites certified for the aerospace market are THERMI-LYON, THERMI-LOIRE, THERMI-GARONNE and, more recently, THERMI-PICARDIE.

    Why is heat treatment used in industry?

    Heat treatment is one of the only ways to improve the mechanical strength of metals, and therefore their performance. Alloys such as steel, stainless steel, aluminum, titanium and copper all have improved mechanical strength, wear resistance, seizure resistance and corrosion resistance thanks to heat treatment.

    Is it possible to harden an aluminum alloy?

    Yes, some aluminum alloys can be quenched and tempered to improve their mechanical strength. This treatment is only available for alloys from the 2000, 6000 and 7000 steel mills. 

    What is the advantage of vacuum processing?

    The main advantages are the ability to obtain perfectly clean parts after treatment, and to significantly limit deformation when cooling under neutral gas. Vacuum technology furnaces are heated by electricity, not gas. What's more, the absence of atmosphere eliminates any risk of oxidation. These processes are the most environmentally-friendly of all heat treatments.
