CW613N
DESCRIPTION
CW613, brass, is a readily extrudable leaded alpha/beta brass with a small Tin addition, which gives little bit of strength and resistance to corrosion. The lead gives free cutting properties. CW613 is available as extruded rods and flats which are typically used in builders’ hardware.
