Neil Metals, based in Kolkata, India, stands out as a top manufacturer and supplier of high-quality Aluminium Hollow Bars and Rods, delivering precision-engineered solutions tailored to a variety of industrial needs. Known for their lightweight nature, impressive strength-to-weight ratio, and resistance to corrosion, these aluminium products are crafted to meet international standards as well as specific customer requirements. Neil Metals caters to a range of sectors, including aerospace, automotive, marine, construction, and general engineering. With cutting-edge manufacturing capabilities, a strong commitment to quality, and prompt deliveries, Neil Metals offers dependable aluminium hollow bar and rod solutions that guarantee optimal performance, durability, and versatility across numerous applications.
Aluminium Hollow Bars and Rods are primarily made of aluminium (over 90%), with alloying elements like silicon, magnesium, manganese, copper, and zinc, depending on the specific grade (such as 6061, 6082, 2011). These materials boast excellent tensile strength ranging from 150 to 350 MPa, high corrosion resistance, and good machinability. The hollow design helps reduce weight while preserving structural integrity, making them perfect for lightweight and efficient components. Additionally, aluminium hollow bars can be heat-treated to improve their mechanical properties, making them suitable for applications that demand high precision, strength, and corrosion resistance in challenging environments.

Yes, aluminum hollow bars are corrosion-resistant due to the natural oxide layer that forms on the surface, providing protection against environmental elements like moisture, air, and chemicals.
Yes, aluminium hollow rods can be customized in both size and length according to specific requirements. Suppliers often offer options for diameter, wall thickness, and cut-to-length services.
Aluminum hollow bars and rods typically perform well in moderate temperatures but may lose strength and structural integrity in high-temperature environments above 200-250°C, becoming prone to deformation and oxidation.
Aluminium Hollow Bars and Rods find extensive use in industries that require strong yet lightweight structural materials. In the aerospace and automotive sectors, they are utilized for frames, drive shafts, hydraulic systems, and precision components. The construction industry employs them for structural supports, curtain walls, and architectural frameworks. In marine applications, their corrosion resistance makes them ideal for masts, rails, and fittings. Furthermore, aluminium hollow bars are also valuable in general engineering, fabrication, and furniture manufacturing, where strength and aesthetics are key considerations.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
