Aeronautics and aerospace industry

In a sector with growing perspectives, Silmax presents a wide range of tools designed to meet the highest quality standards, strict tolerances and the certifications required by the aviation and aerospace industries.

Since the 1980es, Silmax has gained a solid and recognised experience as a leading company in the aeronautical market, providing highly customised solutions for the aviation industry, both for components and for different materials, such as:

  • Superalloys for engine components    
  • AAISI, PH, Titanium for structures
  • Aluminium, Magnesium and Composite Materials for other parts

In this sector, Silmax has been working for many years as a specialised and reliable interlocutor, proposing a large number of HM, as well as HSS solutions, which are particularly suited to machine heat-resistant alloys, (Inconel, Inconel 718, Inconel 625, Waspaloy, Nimonic, Incoloy), high-hardness and composite materials (Kevlar, aeronautical sandwich composites, composite fibers, etc.).

Thanks to these abilities, Silmax cooperates with the leading Italian and international aircraft manufacturers in the development of important programmes, such as:

  • EFHA, F35, C27l for the LEONARDO Group, Aircraft Division, (former ALENIA)
  • BOEING 767, 777, 787 and ATR for the BOEING Group
  • C-Series for the BOMBARDIER Group
  • AW169, AW101, AW189, AW609 and NH9 for the AGUSTAWESTLAND Group, Helicopters Division.
  • In addition, Silmax is certified as a DIRECT MATERIAL SUPPLIER (CRITICAL TOOLS) for the GE Avio Group.

PVD Coatings

Relying on the experience gained during its thirty-year partnership with Oerlikon Balzers, in 2013 Silmax opened a new factory dedicated to PVD coating (physical vapour deposition) in its premises of Lanzo Torinese, with an INGENIA plant using Oerlikon Balzers technology and a robotised,  ultrasound washing system.

Today, there is also a new PVD INNOVENTA kila unit, which, thanks to its advanced technology with latest-generation software and its high production capacity, reduces coating times, and to meet all needs for PVD coating of tools and for R&D activities.

Find out more about the available coatings by visiting the PVD Coatings page.

Machining of aerospace components using tools with Balinit® Tisaflex Coating

Silmax presents an absolute novelty: Balinit® Tisaflex, Balzers coating produced by Silmax with INGENIA systems by Oerlikon Balzers at its Italian factory. Balinit® Tisaflex is the best solution for machining difficult-to-cut materials, for high mechanical resistance steels, chrome steels and tempered steels over 60HRC. Find out more in the dedicated page.


  • Optimised structure: a structure optimised by an AlTiN/TiSiXN-based double layer, a combination that offers ductility, higher hardness and resistance to oxidation and wear.
  • Reduction of micro cracks and chipping: defined stress profile that reduces the formation of microcracks and improves resistance to chipping. 
  • High thermal resistance: the coated tool can withstand the high temperatures on its cutting edge, which have been developed during machining.
  • Reduction of wear: a significant reduction of wear with a consequent extension of tool life, which is crucial in finishing operations.
  • Balinit® Tisaflex: machining of aerospace components.
