What Master Magnetics does

Master Magnetics, Inc. is a privately held U.S. manufacturer and distributor of permanent magnets and magnetic assemblies, founded in 1976 and headquartered in Castle Rock, Colorado, with a second distribution facility in Marietta, Ohio. Operating under the Magnet Source brand, the company maintains over 20 million magnets in stock across five raw material families (neodymium, ceramic, alnico, samarium cobalt, and flexible magnetic sheeting) and produces downstream assemblies including magnetic sweepers, welding magnets, tool holders, retrieving magnets, material-handling magnets, latches, hooks, and clamps. Its product portfolio also includes patented cow stomach magnets for the agricultural segment and the Magnetic Graphics System (PrintMagnetVinyl, ThinFORCE, and FlexIRON) for printable signage and retail display applications.

The company operates a multi-channel go-to-market model spanning direct e-commerce (magnetsource.com), telephone-based business sales for custom and OEM orders, an Authorized Reseller Program with over 250 retail-ready SKUs, and distribution through major retailers and industrial supply partners including Home Depot, Walmart, Ace Hardware, TrueValue, Amazon, DoItBest, Grainger, Fastenal, and McMaster-Carr, reaching over 37,500 retail locations across North America. Revenue is generated almost entirely through one-time product sales (consumer units, retail packaged goods, industrial bulk orders, and flexible material rolls) plus custom cutting, slitting, and bespoke assembly services with 2–18 week lead times. The company serves at least ten vertical segments, with primary emphasis on industrial/manufacturing, agriculture, automotive, construction, safety/warehousing, printing and sign-making, and metal working/welding, and secondary reach into craft/hobby, housewares, and woodworking.

From an operational standpoint, Master Magnetics operates a 99,000-square-foot headquarters and warehousing facility and reports 101–250 employees, with unusually high tenure (19% of staff with over 20 years of service). The business is independently owned with no disclosed venture capital, private equity, or parent company involvement, and reports a BBB A+ accreditation. No public revenue figures, API offerings, AI/ML capabilities, or external funding rounds are disclosed in the available data.

Revenue model

1. Direct Product Sales (E-commerce & Phone): Consumer and business customers purchase magnets directly via the company website and telephone orders. Individual magnet SKUs are priced per unit (e.g., $0.15 for small neodymium discs, $9.91 for ceramic block magnets, $35.65 for flexible magnetic strip rolls). One-time purchase model for individual units and retail packaging.
2. Volume & Bulk Industrial Sales: Industrial magnets priced and packaged for volume purchase. Custom tooling and special orders available for OEM applications. Distributor pricing offered to channel partners. Custom magnet orders typically take 2-18 weeks depending on material and complexity.
3. Flexible Magnetic Material Sales: Flexible magnetic sheeting and strips sold in various thicknesses (12-60 mil), widths (up to 48 inches), and lengths (10-200 ft). Includes printable variants (PrintMagnetVinyl™, ThinFORCE™), magnetic receptive materials, and custom-cut products. Products include rolls, strips, and sheets with adhesive or plain backing.
4. Retail Packaged Products & Display Programs: Over 250 retail-ready SKUs of packaged consumer magnets sold through authorized resellers (hardware stores, home improvement retailers, craft stores). Includes customized planograms, merchandising displays, floor displays, counter displays, and free P.O.P. graphics for retailers.
5. Custom Cutting & Manufacturing Services: Precision custom cutting of flexible magnetic sheeting to specified dimensions. Slitting services to narrower widths. Custom shapes available.
