Hot forging process allow us to manufacture fastening and binding elements in high-performance materials such as :

  • Special steels
  • Stainless steels & high-alloy steels
  • Titanium alloys (Ti-6-4)
  • Nickel alloys (Inconel, Monel, Nimonic,…)
  • Cobalt alloys (CoCR 20WNi)
  • HASTELLOYS among other materials….



As mechanical fastening and binding elements demand both quality and precision, Andre Laurent acquired high-technology machinery :  lathes, machining centre, digitally controlled grinding machine…


Our design and technical team accompany you from the design to the manufacturing of your components to offer you maximum satisfaction.


Our EN9100 Certification allows us to guaranty our aerospace and aviation customers a high standard of quality.

We are certified ISO 9001 (2008), ISO 14001 (2004), EN 9100 (2009), AD 2000‐Merkblatt W0, Subcontractors acc. to NadCap certification, Lloyd’s Register, Germanisher Lloyd…
