Acnis-moteur-AERO_2015

The aeronautical market has been expanding since the 1980s.

More passengers, more comfort, and more security, with economic and environmental constraints that compel manufacturers to reduce the weight of aeroplanes and helicopters, leading to the use of new materials such as carbon fibre reinforced composite materials.

Structural components that are held together by carbon fibres require titanium alloys or other technical alloys, which are increasingly used in modern commercial or military aircraft, but also in the fields of space science, weaponry and car racing because of their special properties.

To compete in the world aeronautical market, every company has to improve its buy-to-fly ratio which is now only 10 kilos fly to100 kilos buy, particularly when using technical metals.

AEROMETALS & Alloys, the only independent French titanium service centre: 500 tons of stock

For 15 years, the ACNIS group company AEROMETALS has been offering solutions to optimise this ratio for grade 5 (TA6V), grade 2 (T40), grade 4 (T60), and grade 3 (T50) titanium grades and less known titanium alloys.

Other technical alloys, such as 15-5PH and 17-4PH stainless steels are currently under study.

Optimisation of titanium plates, sheets and bars is achieved by using high-performance cutting tools: saws for plates/bars, waterjet and laser cutting, shear, decoiling, slitting, etc. AEROMETALS & Alloys provides all these services on its website or with its authorised partners, allowing it to deliver parts within very short timeframes.

A specific, confidential study is made for every part and every optimisation.

AEROMETALS & Alloys:

  • Just-in-time delivery capacity with implementation of bipartite or tripartite contracts (AEROMETALS & Alloys /Customer processor or Material producers/ AEROMETALS & Alloys /Customer processor). The horizon of these contracts (one to three years) allows the whole supply chain to be controlled and streamlined.
  • Investment in new automated sawing machines that offer tighter flow rate tolerances (+/- 0.5mm), thus allowing the weight used to be reduced and/or the subsequent machining operation to be robotised.
  • Investment in waterjet technology allowing shape cutting without thermal degradation of the material or heat deformation and without modifying the structure of the material (no HAZs), with the capacity to cut any type of material intended for the aeronautic market (titanium, aluminium, stainless steels, nickel alloys, etc.) to thicknesses of up to 120 mm with great precision.
  • Investment in nesting software designed to optimise material utilisation: with savings rapidly reaching 20 or 30% according to the geometric complexity of the shape and the number of parts to be cut (photo link 4)
  • Customs bonded storage
  • Integration of outsourcing operations (heat treatment, machining, etc. )
