Leading Gun Metal Flanges Manufacturer, Supplier & Exporter – Technical Overview by Creative Piping Solutions Pvt. Ltd.
Leading Gun Metal Flanges Manufacturer, Supplier & Exporter – Technical Overview by Creative Piping Solutions Pvt. Ltd. – Gun Metal, popularly known as Red Brass or by designations such as RG5 and C83600, is a time-tested alloy trusted for its reliability and corrosion resistance. Its balanced composition of copper, tin, zinc, and lead makes it ideal for flange manufacturing. Creative Piping Solutions Pvt. Ltd., a leading manufacturer, supplier, and global exporter of Gun Metal Flanges, produces components designed to perform consistently in demanding marine, water supply, hydraulic, and engineering environments.
This article offers a complete technical overview, covering material composition, mechanical strength, available flange types, industry standards, applications, and testing procedures followed by our company.
Introduction to Our Gun Metal Flanges
Gun Metal Flanges are produced from a copper-based alloy engineered to withstand corrosion, pressure, and temperature variations. Typical composition:
Copper: 85–88%
Tin: 5–8%
Zinc: 3–5%
Lead: 2–5%
The presence of tin strengthens the alloy, zinc enhances fluidity, and lead improves machinability. As a result, Gun Metal becomes an excellent choice for components used in marine water systems, pump assemblies, valves, hydraulic circuits, and long-term outdoor installations.
Dimensional Range (ASME B16.5 – Class 150)
Gun Metal Slip-On Flanges under Class 150 are available in standard sizes ranging from ½” to 12”. These dimensions include bore diameter, outer diameter, thickness, raised-face size, bolt circle, and approximate weight. With consistent machining and exact tolerances, these flanges ensure leak-free connections and secure bolting.
Chemical Composition – RG5 / C83600
Gun Metal used by Creative Piping Solutions meets the following chemical structure:
Copper: 84–88%
Tin: 5–8%
Zinc: 3–5%
Lead: 2–5%
Nickel: ≤1%
Iron: ≤0.3%
This composition offers a balance of strength, anti-corrosion ability, and casting quality.
Mechanical Properties
Gun Metal Flanges deliver excellent mechanical performance:
Tensile Strength: 210–260 MPa
Yield Strength: 90–120 MPa
Elongation: 12–18%
Hardness: 65–80 HB
Melting Temperature: 850–950°C
Density: 8.7–8.9 g/cm³
These properties make the alloy dependable for pressure lines, seawater pipelines, and machinery parts.
