Nimonic 90 Nickel Alloy Round Bar UNS N07090 2.4632 Wire

NIMONIC alloy 90 ( UNS N07090, EN 2.4632, 2.4969 )
is a wrought nickel-chromium-cobalt base alloy strengthened by additions of titanium and aluminum.

It has been developed as an age-hardenable creep resisting alloy for service at temperatures up to 920°C

Material NIMONIC 90 offers the following key features:

• High stress rupture strength and high creep resistance at high temperatures
• Good resistance to high-temperature corrosion and oxidation
• Age hardenable
• High temperature dynamic applications

Nimonic 90 is a precipitation hardenable Nickel-Chromium-Cobalt alloy with high strength at temperatures

up to 1300°F (704°C) and creep and oxidation resistance up to 1688°F (920°C).

Industries served
Oil & Gas Extraction and Processing, Nuclear, Aerospace, Power Generation and Automotive, fasteners.

Springs operating from ambient temperatures up to 1112°F (600°C), fasteners and components requiring

resistance to high temperature and corrosive environments.
