Leaded Brass Hollow Rods

We are manufacturer of brass hollow rods and brass hollow bar with wide range of inner and outer diameters, alloys & grades. These rods and bars are said to be the best alternative for machined parts which has bore like cable glands, brass sleeves, valves and various other brass components which has bore in its center. Being hollow, these rods need not require to make bore as done in regular brass rods so it reduces the production time which would have been wasted in making bore, tooling costing and also scrap. As brass hollow rods makes less scrap compared to brass extrusion rods, raw material required as input is also reduced and which in-turn reduce the working capital also.

Free Cutting Hollow Rods
