A “C” core is a piece of magnetic material with a high permeability used to confine and guide magnetic fields in transformers, electric motors, generators, and other magnetic devices.  Specialty Metal Products Company processes for stock and supply of specialty hardware, metal strapping and clips for use in the assembly and banding of “C” cores.  Materials include tin-coated steel, brass, phosphorous-bronze, and stainless steel.  Certain applications may require a non-magnetic strap, such as stainless steel or phosphorous-bronze.  Pneumatic tensioning tools are also in stock and available for immediate shipment.  Drawings are available upon request, for all of our “C” core hardware. 

Please Note: The customer is responsible for determining the suitability of materials used and assumes all risks resulting from the use of Specialty Metal Products Company C-Core banding products.  The customer must confirm adaptability thereof by their own test needs.  All support documents substantiating origin, materials, and processes are maintained on file, and available upon request.  All products are of domestic origin and acceptable under the guidelines set forth in ROHS, REACH, and WEEE.  All C-Core products are Conflict Minerals Compliant.
