Brass Finned Tubes Manufacturer and Supplier in India
Brass Finned Tubes are manufactured to meet the demands of requiring high thermal conductivity and corrosion resistance, making them suitable for use in heat exchangers where heat dissipation and durability are key requirements. The tubes are produced by winding, extruding or machining outside fins on to a brass base tube, which results in a higher surface area for heat transfer but allows the tube to retain its structure. Typical proportions of copper and zinc in most grades of brass for finned tubes are about 60–70% Cu and 30–40% Zn; thermal conductivity is up to 120 W/m·K; tensile strength is 300–500 MPa,
depending on the grade of brass. Amardeep Steel is a reliable Brass Finned Tubes manufacturer in India and also a supplier of Brass Finned Tubes that delivers precision engineered finned tubes in custom sizes, fin profile and material grade that are required to adhere to international quality standards.

Frequently Asked Questions
1. What are Brass Finned Tubes?
Brass Finned Tubes are heat exchanger tubes with external brass fins designed to increase surface area and improve heat transfer efficiency.
2. How are Brass Finned Tubes manufactured?
They are manufactured by attaching fins to a brass tube using processes such as winding, extrusion, or machining, depending on the application requirements.
3. Why is brass used for finned tubes?
Brass is used because it offers excellent thermal conductivity, good corrosion resistance, high strength, and long service life in cooling and heat exchange applications.
4. What is the difference between Brass Finned Tubes and Copper Finned Tubes?
Brass Finned Tubes provide better mechanical strength and corrosion resistance, while Copper Finned Tubes offer higher thermal conductivity but are softer and less durable.
5. Are Brass Finned Tubes corrosion resistant?
Yes. Brass Finned Tubes have excellent resistance to corrosion in cooling water, seawater, and many industrial process fluids, making them suitable for demanding environments.
