When a major industrial furnace manufacturer faced repeated heating element failures due to oxidation and thermal cycling, the solution came with Nichrome Round Bars. These nickel-chromium alloys, renowned for their exceptional high-temperature resistance and electrical properties, transformed their heating systems delivering consistent performance, extended service life, and reduced maintenance costs. Today, engineers and procurement teams across chemical, oil & gas, marine, pharma, and power generation industries trust Nichrome for their most demanding heating and high-temperature applications.

Nichrome, particularly the 80/20 composition (UNS N06023), consists of approximately 80% nickel and 20% chromium, creating an alloy with outstanding oxidation resistance, high electrical resistivity, and excellent mechanical strength at elevated temperatures. This unique combination makes Nichrome ideal for heating elements, furnace components, and high-temperature applications where ordinary steels would fail. The alloy maintains structural integrity up to 1100°C while providing uniform heat distribution and consistent electrical resistance.
As a trusted Nichrome Round Bars supplier, manufacturer, and stockist, Aurico Alloys LLP provides affordable, best-quality, authentic materials for chemical, oil & gas, marine, pharma, and power generation industries, along with hardware and industrial supply stores. Available in diameters from 1mm to 200mm with various finishes including bright, polished, and hot-rolled, these bars are supplied with complete mill test certificates and international standard compliance.
Compared to standard heating alloys, Nichrome's superior oxidation resistance, thermal stability, and fabricability make it the preferred choice for critical heating applications. Its resistance to scaling and corrosion even at red-hot temperatures ensures reliable performance in industrial furnaces, aerospace heating systems, and chemical processing equipment where failure is not an option.
High-quality Nichrome Round Bars ready for industrial use.

Mechanical & Physical Properties
Density, electrical resistivity, thermal conductivity, specific heat, expansion, modulus and maximum operating temperature are published for each of the three grades in the Equivalent Grades & Standards tables above, read off the VDM Metals sheet named beneath each one.
Room-temperature strength, elongation and hardness of a nichrome bar depend on the diameter and the temper it is drawn to, so they are quoted against your size rather than published as one figure for the grade. The mill test certificate supplied with your order states the results for the material you receive.
