Corrosion-resistant alloys (NR-7, 8, 9)
These alloys are remarkably corrosion-resistant and deepdrawable.
They also have aesthetic appeal.
Corrosion-resistant alloys (NR-11, 12, 15)
These alloys are basically composed of nickel and chromium, and are used for making spectacle frames because they are corrosion resistant, springy, and easy to cut and process.
Heat-resistant alloys (IL)
Having both heat-resistant and corrosion-resistant properties, these alloys are used for a wide variety of applications.
