DESCRIPTION
CW714R naval brass. Mostly used for machine hardware, screw machine products and valve
stems, CW714R naval brass is great for hot forging and pressing and machining. With high
ductility, naval brass has excellent electrical and thermal conductivity. CW714R naval brass
has good creep resistance and high impact strength.
