CW613N

CW613, classified as brass, stands as an easily extrudable alloy combining alpha and beta phases with a minor infusion of tin, contributing a slight enhancement in strength and corrosion resistance. The inclusion of lead imparts free cutting characteristics. CW613 is accessible in the form of extruded rods and flats, commonly employed in the domain of builders’ hardware.
