USE OF AN ELECTRICAL CONTACT MATERIAL FOR BLOWING AN ELECTRIC ARC
The material has an array of conductor metal and non-magnetized magnetic entities, where the entities are magnetized with an average orientation defined by a direction of a magnetic field applied on the material for blowing an electrical arc between electrical contact studs. Each electrical contact...

| description | The material has an array of conductor metal and non-magnetized magnetic entities, where the entities are magnetized with an average orientation defined by a direction of a magnetic field applied on the material for blowing an electrical arc between electrical contact studs. Each electrical contact stud has an upper layer that comprises material such as silver or copper, or stable refractory compound. The magnetic entities are rare earth based hard magnetic compounds such as nanostructured alloy of neodymium/praseodymium, iron and boron. An independent claim is also included for a method for fabricating an electrical contact stud. |
