Product Overview
Introduction To Nimonic Alloys
MOKSH TUBES & FITTINGS LLP is a leading supplier, stockist, and exporter of high-performance Nimonic Alloys, known for their exceptional resistance to heat, oxidation, and corrosion. These nickel-chromium-based superalloys are engineered for extreme temperature applications where mechanical strength and structural stability are vital—especially in aerospace, gas turbines, nuclear reactors, and high-stress environments.
Nimonic Alloys are primarily composed of Nickel (Ni) and Chromium (Cr), often combined with Titanium (Ti) and Aluminum (Al) for precipitation hardening. Popular grades include Nimonic 75, 80A, 90, 105, 263, and others—each suited to specific mechanical and thermal requirements.
