Hollow Brass Rods
Hollow brass rods are produced in variety of copper alloys mainly for the manufacturing of fittings. Hollow brass rods are also available with shaped ends (chamfered/pointed) according to international standards or upon agreement.
Alloys
CW614N, CW603N, CW602N, CW617N, CW724R. Other alloys upon request.
Temper
Hollow rods are delivered thermally stress relieved. Other tempers upon request.
Packing
Bundles.
