Adarsh Nickel Alloys is a trusted manufacturer and supplier of premium-quality Invar Bars in Delhi, serving industries that demand exceptional dimensional stability and precision. Produced under strict quality control, these bars are known for their extremely low thermal expansion and reliable performance in temperature-sensitive environments. Adarsh Nickel Alloys focuses on consistent chemistry, accurate sizing, and smooth surface finishes to meet diverse industrial needs. Invar Bars supplied by the company are widely appreciated for their durability, stability, and ability to maintain shape and accuracy, even under fluctuating thermal conditions.
Invar is a nickel-iron alloy typically containing around 36% nickel, with the balance being iron and minimal trace elements. This unique composition provides an exceptionally low coefficient of thermal expansion. Invar Bars exhibit moderate tensile strength, good ductility, and excellent dimensional stability over a wide temperature range. The alloy offers reliable machinability and maintains its structural integrity without distortion. These mechanical characteristics make Invar Bars suitable for precision components requiring consistent size, shape, and performance during thermal variation.
