C38000

C38000, categorized as Section brass, represents an easily extrudable alloy featuring a blend of alpha and beta phases, with the incorporation of a minor amount of aluminum resulting in a distinctive bright golden hue. The inclusion of lead imparts free cutting characteristics. C38000 is accessible in the form of extruded rods and flats, commonly employed in the realm of builders’ hardware.
