Soft Magnetic Composites (SMCs) for electric motors: A new era driven by automotive and aviation electrification

The rapid global adoption of Electric Vehicles is taking Powder Metallurgy towards a promising new era in electric motor manufacturing. Soft Magnetic Composites (SMCs) offer an enhanced approach to motor design, reducing energy losses while enabling compact, innovative motor architectures. Beyond Electric Vehicles, the aerospace sector is seeking to leverage these lightweight and efficient PM electric motor technologies for aircraft propulsion systems.

In this article, John Morehead presents the various electric motor types used for vehicles and highlights applications and innovations around SMCs.

Keep your powder dry: The overlooked impact of moisture in metal powders

Metal powders underpin many advanced manufacturing processes, yet one often-overlooked factor can significantly affect their performance: moisture. Excess moisture reduces flowability, accelerates oxidation, and increases the risk of porosity in finished parts. While standards do exist, traditional testing methods rarely offer real-time insight.

In this article, Dr Peter Moir and Dr Martin McMahon examine how moisture interacts with metal powders, the impact on processing, and how emerging measurement techniques can help safeguard powder quality and consistency.

PM-HIP: The alternative to casting and forging that improves supply chain flexibility and sustainability

Powder Metallurgy Hot Isostatic Pressing (PM-HIP) is an advanced manufacturing process that enables the production of large, high-integrity components with consistent, forged-like properties. As traditional casting and forging supply chains face growing challenges, PM-HIP offers a reliable alternative with shorter lead times and increased design flexibility.

Here, Amaero’s Eric Bono explains how the process supports resilient, domestic production of critical parts across sectors such as defence, energy, and aerospace, helping manufacturers reduce dependency on constrained supply chains while achieving demanding performance requirements.

Producing copper powder from industrial waste: Destiny Copper’s sustainable recovery process

Destiny Copper has developed a patented, chemistry-based process to recover high-purity copper powder from mining and industrial waste streams. Using a zero-energy, modified cementation process, the company extracts copper without the need for electrowinning or melting, significantly reducing energy use and emissions. With support from federal and regional innovation programmes, Destiny Copper is now scaling up its operations to meet the growing global copper demand while turning hazardous waste into valuable materials for advanced manufacturing applications.

Here, the company’s Lead Scientist, Dr Josh Clarke, shares insight into the story so far.

The 2024 Japan Powder Metallurgy Association Awards: Recognising innovations in PM

The 2024 JPMA Awards, organised by the Japan Powder Metallurgy Association (JPMA), celebrate outstanding innovations in Powder Metallurgy across product development, process improvement, and material advancement. This year’s award-winners showcase the latest achievements in performance, sustainability, and manufacturing efficiency, highlighting the industry’s ongoing evolution. From Electric Vehicle components to powders for PM and Additive Manufacturing, the awards demonstrate the versatility and potential of PM technologies in meeting the demands of next-generation applications across diverse industries.
