Copper alloys provide optimal conductivity applications that require high levels of electrical energy. But these metals suffer from surface damage, such as gouges and abrasions, from strong magnetic fields. A coating of molybdenum or tantalum offers adequate protection, but these metals differ from copper in toughness, thermal conductivity, refractory expansion coefficient and other properties. Developers at Materials & Electrochemical Research (MER) Corp. have engineered a solution. Rather than coating a high-melting-point refractory metal onto copper, they have made a Refractory Metal Coated Copper foil, applied as a clad layer through plasma transferred arc melting. This method clads virtually any metal to another metal independent of their diversity in properties, and provides corrosion and wear resistance, hardness and coefficient of friction for a variety of aerospace, defense and transportation applications.
