Neil Metals is a reliable producer and supplier of Monel Hollow Bars, based in Kolkata, India. Known for high-grade nickel-copper alloys, Neil Metals provides precision-engineered Monel solutions that work with consistency in harsh and stressful conditions. Monel Hollow Bars are produced through sophisticated metallurgical processes to achieve superior dimensional accuracy, strength, and corrosion resistance. Industrial sectors like marine engineering, oil & gas, chemical processing, and defense are served by Neil Metals with tailor-made solutions to satisfy various industrial requirements. Prioritizing quality, service, and punctual delivery, the company is an entrenched favourite as a prime supplier of high-quality hollow bar stock.
Monel Hollow Bars are generally manufactured using Monel 400 or Monel K500 alloys. Monel 400 is about 63% nickel and 30–34% copper with residual amounts of iron, manganese, and silicon and is noted for its excellent corrosion resistance and good mechanical strength. Monel K500 introduces aluminum and titanium, which gives it greater tensile and yield strength with the same corrosion resistance. Mechanical properties vary between 550–860 MPa tensile strength and 170–690 MPa yield strength based on grade and condition. Monel Hollow Bars come in different outer and inner diameters and wall thicknesses to suit the needs of particular applications.
