Several years ago Rizzardi introduced Aluminum pulleys with ceramic coating.These pulleys, which offer great resistance to wear, have solved a problem experienced in wire drawing.
The wire travels with extreme facility on the pulley, practically eliminate the maintenance in this sector.
One of the main advantages of this coating, beside greater resistance to wear, is its high level of elasticity which prevents its detachment by thermal shocks.
Laboratory tests have proven that  heating a Rizzardi Aluminum Pulley with the ceramic coating to a temperature of 400°C and cooling repeatedly in water, no coating detachment occured and the characteristics of the coating remain unchanged.
With this coating, the Rizzardi Pulleys are manufactured in various shapes and sizes, to meet customer requirements
