We are manufacturer of Brass Hollow Round Bars / 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.
Size:Maximum OD: 100mm
Minimum Bore Size: 15mm
Types:Round Hexagonal Square
Material Grades:
We are manufacturing brass hollow rods and bars in wide range of alloy. The standard alloy grades are mentioned below and if any custom alloy or grade is required kindly contact us for more details.
Free Cutting Hollow Rods
Use: These hollow rods are mainly used in manufacturing high speed machining components with a large hole in it, which consumes large production time in making center hole and turning operations.
Industry using free cutting hollow rods are Precision Components, hardware, cable glands, automobile components and electronic parts.
Grade-1 / Grade-2 (IS 319/89)BS 2874/86 – Cz121 Pb3Cz124
Forging Hollow Rods
Use: These hollow rods are mainly used in manufacturing forged components and pressing materials and hence used mainly in making valve components..
Industry using forging hollow rods are forged components, industrial valves, defense components, watch case and automobile valves components.
Cz122IS 8737IS 3488/80
High Tensile Hollow Rods
Use: As these hollow rods highly resistance against corrosion and high in strength they are used and making marine components and sanitary parts.
Industry using high tensile hollow rods are Marine Industry and sanitary parts industry.
IS 8737 / AMD-2
Lead Free Hollow Rods
Use: Also known as reverting quality brass rods, these hollow rods are used mainly in making watch case and hot forging components.
Main industry using lead free hollow rods are watch case making companies. Brass Extrusion Bars International Standards

In designing a component, it is very essential to take the production costs into consideration to keep it as low as possible while maintaining the quality.
We, at DOWEDO, produce Hollow Rods in Round, Hex and Squares shapes which we can offer to our customers to reduce the production costs. Standard shapes of hollow bar are available which often proves to be a more cost-effective choice for the manufacture of hollow components.
Although hollow extrusions cost more per unit weight than solid bars, this is frequently offset by the saving in drilling and reduction of swarf. Using modern production techniques the eccentricity of hollows is minimal.
Outer Diameter Range: 22 mm to 75 mm
Inner Diameter Range: 12 mm to 40 mm
Minimum wall thickness: 4 mm on each side.
