Gunmetal Round Pipe
Manufacturer,Stockist and Exporter of Gunmetal Round Pipe
Gunmetal Round Pipes are high-quality metal pipes made from a copper-tin-zinc alloy, also known as gunmetal. Known for their excellent strength and corrosion resistance, they are widely used in various industrial applications.
Sumer Metal Industries Private Limited is a leading manufacturer, supplier, and exporter of Gunmetal Round Pipes. With decades of experience in the metal industry, the company ensures superior quality and timely delivery of its products.Global Export Reach
The company exports Gunmetal Round Pipes to multiple countries, including Oman, Qatar, Saudi Arabia, UAE, Kuwait, Spain, Germany, USA, Canada, and various regions across Africa, catering to diverse industrial needs.
Gunmetal Round Pipes are primarily composed of copper, tin, and zinc, with small amounts of lead, iron, and nickel. This composition gives them excellent mechanical strength and corrosion resistance.
The pipes are manufactured according to international standards like IS 318, ASTM B505, and BS 1400, ensuring global compatibility and reliability in industrial applications.
These pipes are widely used in pumps, valves, bearings, hydraulic systems, and marine equipment. Their durability and resistance to wear make them suitable for heavy-duty industrial use.
Sumer Metal Industries produces both seamless and welded Gunmetal Round Pipes. Seamless pipes are preferred for high-pressure applications, while welded pipes are cost-effective for general industrial use.
Gunmetal Round Pipes can withstand temperatures ranging from -50°C to 250°C, making them suitable for hot and cold fluid transfer in industrial processes.
The high copper content, combined with tin and zinc, provides excellent corrosion resistance. This makes these pipes ideal for use in marine and chemical industries.
Gunmetal Round Pipes exhibit high tensile strength (350-450 MPa), good yield strength (200-250 MPa), and elongation of 10-25%. Their Brinell hardness ranges from 80-120 HB, and density is around 8.3-8.8 g/cm³.

Gunmetal Round Pipes have equivalent grades under different standards: IS 318 corresponds to LM6, ASTM B505 to C83600, and BS 1400 to LG2.
These pipes are available in a wide range of nominal bores and wall thicknesses, from 15mm to 80mm and above, with custom sizes available on request.
Sumer Metal Industries exports Gunmetal Round Pipees across the Middle East and beyond — Oman, Qatar, Saudi Arabia, the UAE and Kuwait — and into Europe and North America, including Spain, Germany, the USA and Canada, as well as several regions across Africa. Their export packaging is sea-freight ready, with oil-coating, plastic wrapping and wooden crates or palletization to protect finished parts during long transit.
A broad size range is offered, from small-diameter bushings for instrumentation to large liners for industrial shafts; custom lengths, stepped bores and flanged options are routinely produced to customer drawings. The plant supports one-off prototype runs for OEM development as well as higher-volume repeat production for distributors and aftermarket suppliers.
Chemical Properties Of Gunmetal Round Pipe

| Tin (Sn) | 5 - 10 |
| Zinc (Zn) | 2 - 5 |
| Lead (Pb) | 0.5 - 3 |
| Iron (Fe) | 0.05 - 0.5 |
| Nickel (Ni) | 0.05 - 0.3 |
Sumer Metal Industries provides application support to help customers choose the correct alloy variant and finish based on load, speed, shaft material and operating environment. Their engineering team will advise on clearance tolerances, run-in procedures and whether a split- or full-section bush is most appropriate for installation and future servicing.
Installation guidance and maintenance recommendations come with supply: correct press-fit allowance, alignment checks and lubrication practices are specified to maximize service life and reduce the risk of shaft scoring or premature wear. For critical rotating machinery, they recommend routine inspection intervals and simple non-destructive checks that can detect early wear patterns.
Sustainability and material stewardship are considered in their process: efficient machining with minimal scrap, responsible disposal of cutting fluids and the option to remelt and reuse in-house swarf where feasible help reduce material waste. Customers with circular-economy goals can request material-return programs for end-of-life components.
