^LUXEMBOURG, Jan. 20, 2026 (GLOBE NEWSWIRE) — Aperam, a global
Companies in the fields of stainless steel, electrical steel, alloys and
Special steels as well as recycling and renewable energies, announces the introduction
its innovative “Slinky” manufacturing process. This new technology
allows the production of slinky stators and rotors through a helical
Winding process in the plane.
This process is already used in the electrical steel industry. The
However, Aperam’s breakthrough lies in the adaptation of this process to iron
Cobalt alloys (FeCo), which are known to have exceptional magnetic properties
have performance but are difficult to shape. This progress opens up new ones
Design options with significant material savings and thus represents a
more sustainable and efficient solution for the production of
high-performance electric motors.
With the new “Slinky” process, Aperam is setting new standards for the future of the
carbon-neutral mobility, especially in aviation, with eVTOL
Airplanes (vertical take-off and landing electric aircraft) and
Hypercars. Instead of stamping components from sheet metal – a method with high
Material waste – the “Slinky” process creates a unique combination
linear punching and spiral bending in the plane
Form engine components from continuous strips. This innovation
reduces metal waste to only 10 to 30%, compared to conventional ones
Methods that waste up to 70% of this valuable material.
Frederic Mattei, CEO Alloys & Specialties and CIO at Aperam, said:?FeCo-
Alloys are characterized by unparalleled magnetic performance,
but their cost has a history of efficient use
restricted. With “Slinky” we reduce waste significantly and enable
the development of more efficient electric motors that enable our customers
to meet the growing demands of sustainable mobility.”
The heart of the “Slinky” innovation is the AFK family of iron-cobalt
Aperam alloys include IMPHY® AFK1, AFK18 and AFK502R. This
Materials are already being used in the aerospace industry because of their
exceptional magnetic properties – e.g. B. the highest
Saturation induction among all known magnetic materials – preferred
used.
When Aperam’s AFK materials are combined with the “Slinky” process
the performance improvements are convincing:
* +35% power density for eVTOL aircraft
* +25% torque for hypercars
* -15% engine size, critical to aviation weight restrictions
These benefits support the goals of advanced electric propulsion
and are consistent with aviation’s goal of zero by 2050
cause more carbon emissions. This strengthens the long term
Aperam’s innovation strategy.
