Eural Gnutti, a global specialist in drawn aluminium alloy bars for machining, is working with Tornos France to demonstrate the machining and performance advantages of its lead-free 2033 aluminium alloy for high-precision applications.
Tornos France, part of the Swiss-based Tornos Group, is a major manufacturer of sliding-head and precision turning machines, serving sectors such as automotive, medical and luxury goods. The collaboration reflects growing industry demand for sustainable, lead-free materials capable of delivering high machining performance without compromising process reliability or surface quality.
At the centre of the project is Eural’s 2033 alloy, developed specifically to provide high machinability, chip control and operational consistency during high-speed machining. The material has proven particularly effective in supporting precision turning operations involving tight tolerances and demanding production cycles.
The alloy is attracting strong interest from luxury goods and watchmaking manufacturers seeking alternatives to traditional leaded brass materials. In addition to meeting increasing environmental and regulatory requirements, the alloy delivers bright, uniform surface finishes suitable for decorative treatments and coatings, including gold, silver and palladium.
To demonstrate the alloy’s capabilities, Tornos showcased a live machining application at the recent Simodec exhibition in France using its Swiss XT lathe. The machine produced a metal pocketknife featuring a handle machined entirely from Eural 2033 alloy, alongside stainless steel and titanium components. The demonstration highlighted the material’s high chip fragmentation, machining stability and surface finish.
“This application showed the efficiency of Tornos machines when machining a high-performance material such as Eural Gnutti’s 2033 alloy,” states Patrice Armeni, director of Tornos France.
Sébastien Vadillo, sales Manager France at Eural Gnutti, adds: “The collaboration enabled us to identify the optimal machining parameters and confirm the value of 2033 in new application areas.”
