Alliance LLC
Alliance LLC is a Valparaiso, Indiana-based ISO 9001:2015 certified supplier of permanent magnets and magnetic assemblies serving OEM engineers worldwide across the full range of hard magnetic materials — sintered and bonded NdFeB including radial oriented and injection molded grades, samarium cobalt, alnico, ceramic ferrite, and compression bonded SmCo and ferrite — with a particularly comprehensive grade selection across each material family. The company offers end-to-end supply chain services including state-of-the-art manufacturing, ocean/rail/air logistics management, engineering support, design consultation, prototyping, magnetizing, and testing, and has been actively responding to the 2025 Chinese rare earth export control situation by publishing downloadable grade tables of heavy rare earth-free NdFeB magnets that do not require an export license — a practical resource for engineers navigating supply chain disruption. Alliance’s rotor assembly program is a particular strength, offering sintered NdFeB rotors with retaining sleeves, radial oriented rotors, hot pressed rotors, containment sleeve configurations, bonded NdFeB rotors, and multi-pole NdFeB arc rotors for motor OEMs requiring engineered permanent magnet rotor solutions.
