coil winding technology enamelled copper wires up to a diameter of approx. 0.3 mm can be torn normally by a tearing pen that passes close to the post of the coil or the wire guiding nozzle itself. the separating point should be very close to the post of the coil in order not to impede a subsequent contacting process (sering, welding etc.).plating plating is a surface covering in which a metal is deposited on a conductive surface. plating has been done for hundreds of s; it is also critical for modern technology. plating is used to decorate objects, for corrosion inhibition, to improve serability, to harden, to improve wearability, to reduce friction, to improve paint adhesion, to alter conductivity, to improve ir reflectivitymetal types and recycling processmar 05, · metals can be recycled repeatedly without altering their properties. according to the american iron and steel institute (aisi), steel is the most recycled material on the planet. the other highly recycled metals include aluminum, copper, silver, brass, and g.steel market analysis steel price news forecasts crucovering all major markets, our price indices are established benchmarks on which supply chain partners can confidently base transactions. for example, crus us midwest hot rolled coil price, the cru , is the leading steel benchmark in north america and is also used in the settlement of
