Aperam introduces innovative “slinky” solution – a new approach to iron-cobalt alloy components for high-performance electric motors

Core Insights - Aperam has launched an innovative "slinky" production method that utilizes an in-plane helical winding process for creating slinky stators and rotors, enhancing efficiency in electric motor production [1][2]. Group 1: Technology and Innovation - The "slinky" method adapts existing technology from the electrical steel industry to iron-cobalt (FeCo) alloys, known for their superior magnetic performance but difficult formability, thus enabling new design possibilities and material savings [2]. - This method significantly reduces material waste in production, cutting metal scrap to just 10–30% compared to conventional methods that can waste up to 70% [3]. Group 2: Market Applications - The "slinky" production method supports the future of carbon-neutral mobility, particularly in sectors such as aviation, eVTOL aircraft, and hypercars [3]. - The combination of Aperam's AFK family of iron-cobalt alloys with the "slinky" process leads to substantial performance improvements, aligning with aviation's goal of achieving net-zero carbon emissions by 2050 [5]. Group 3: Performance Metrics - The new method results in a 35% increase in power density for eVTOL aircraft, a 25% increase in torque for hypercars, and a 15% reduction in motor size, which is crucial for meeting aviation weight constraints [6].
