Alnico Magnet

Established in 1976 in Castle Rock, Colorado, Master Magnetics Inc. is a leading manufacturer and distributor of top-tier magnets and magnetic devices for commercial, industrial, and consumer uses. Our esteemed brand, The Magnet Source®, signifies superior quality, expertise, and exceptional customer service. With over 20 million magnets in stock and regional distribution facilities, we ensure prompt and cost-effective delivery across North America.

Alnico magnets are a cornerstone of our extensive product lineup. These magnets, composed of aluminum, nickel, cobalt, copper, iron, and sometimes titanium, come in both cast and sintered varieties. Cast alnico is produced by melting and molding the material, followed by a heat treatment process to boost its magnetic properties. Sintered alnico, meanwhile, is made by pressing a powdered mixture into a die and sintering it in a hydrogen atmosphere. Both types exhibit high magnetic strength and stability but require careful handling due to their brittleness and potential for demagnetization if stored incorrectly. Proper storage, such as using steel keepers or ensuring the poles attract each other, helps maintain their magnetic power. We also offer precision grinding and cutting services to tailor alnico magnets to your specific needs.

Master Magnetics excels in meeting diverse magnetic requirements, whether for intricate industrial applications or everyday consumer products. Our vast inventory and specialized services position us as the premier source for all your magnetic needs.
