CW616N

DESCRIPTION

CW616N, 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. CW619 is available as extruded rods and flats which are typically used in builders’ hardware.
