What Challenges Affect the Recycling Of Recycled Alnico Magnets Materials? Material Contamination Issues Contamination is one of the most significant obstacles in Alnico magnet recycling. Adhesives, coatings, and dopants from various manufacturers create complex contamination scenarios, reducing recovery yields. High-quality magnets free from excessive glue, paint, or foreign materials are easier to recycle compared to [...]

A Guide to the Alnico Magnet Recycling Process Hidden within every discarded Alnico magnet lies valuable metals worth recovering. These permanent magnets contain cobalt and nickel, two strategically significant rare metals with high market value and increasingly tight global supply chains. The metals in these magnets represent significant economic value that is often discarded. Environmental [...]

Processing-Driven Microstructure Control in Additively Manufactured Alnico Permanent Magnets This work investigates the process–structure–property relationships in cobalt-free Alnico-3 permanent magnets fabricated using directed energy deposition (DED), a laser-based additive manufacturing technique. Systematic variation of laser power, scan speed, and powder mass flow rate is considered through the framework of global energy deposition (GED), a derived [...]

Application of Alnico Magnets In the vast universe of magnetism, Alnico magnets stand out for their remarkable properties and versatile applications. Comprised of aluminum (Al), nickel (Ni), cobalt (Co), and often including iron and other metals, Alnico magnets were developed in the 1930s and have since been integral to a myriad of technological advancements. Their [...]
