Invar Round Bar
What is Invar Round Bar ?
Invar Round Bar consists of a nickel-iron alloy that has very low thermal expansion. It’s best suited for those parts requiring dimensional stability across temperature variations. Parag Metal provides Invar bars with a standard nickel content of about 36% which provides them with stability and strength. These bars show excellent mechanical and physical properties—good strength, toughness, and a density of about 8.1 g/cm³. Commonly referred to as Nilo Bar, this material is often used in precision engineering.
We supply Invar bar stock in various sizes and finishes. Sizes range usually from 6mm up to 200mm diameter. Whether you require Invar Rod stockist assistance or particular invar material hex bar requirements we can assist. The surface is free from blemish, smooth, and ready for machining. All of the bars are to industry tolerances and can be supplied in cut-to-length form if necessary. Our stock is always ready for quick dispatch to meet urgent requirements.
