Many highlight how the precise dimensional control and customizable finishes allow seamless incorporation into final products without compromising aesthetics or functionality. Engineers appreciate the quick turnaround on sample requests and responsive support during quality assurance testing. Frequently Asked Questions: What makes N42 different from other NdFeB grades? N42 offers an excellent balance between magnetic strength and cost-effectiveness, making it ideal for applications where maximum performance isn't required but consistency and reliability are essential. It typically has a Br (residual induction) of around 1.25–1.35 Tesla and Hc (coercivity) of 800–900 kA/m. Can I order custom sizes or shapes? Yes, we offer OEM services for bespoke magnet geometries, including discs, rings, blocks, arcs, and complex profiles, all within our minimum size capability of D2 x 1 mm. Are these magnets safe for use in consumer products? Absolutely. With proper handling and protective coatings such as nickel or black epoxy, they meet international safety standards for non-toxicity, mechanical stability, and environmental resistance. How do I ensure optimal performance in my application? We recommend consulting with our technical team early in the design phase to determine the best orientation, mounting method, and environmental protection strategy based on your operating conditions—temperature, humidity, and mechanical stress levels.
