63 nickel alloy grades, grouped by family. Inconel, Incoloy, Hastelloy, Monel, the precipitation hardening superalloys and commercially pure nickel — each page carries the composition, mechanical properties and the equivalent designations so a UNS number, a Werkstoff number or a trade name all lead to the same place.
If you know the UNS number, search for it directly. If you are choosing, the family tells you what the alloy is built to resist: nickel-chromium for oxidation and high temperature, nickel-molybdenum for reducing acids, nickel-copper for seawater. The nickel alloy overview compares them side by side.

Not sure which alloy
Send the media, the temperature and the strength required and we will narrow it down — including where a cheaper grade will do the job. The standards library has the AMS and ASTM specifications behind these grades.
