  • Nickel-Manganese Alloy Grades Ni211 Ni212

Nickel-Manganese Alloys: Wire / Strip / Ribbon

Ni 211 Nickel 211 is similar to Nickel 200 with manganese addition to improve resistance against sulfur at high temperatures. This allows for the use of this alloy in applications where sulfur is present in heating flames, such as in proximity to glass seals. It also retains higher strength than Nickel 200 at higher temperatures.

Ni 212 Nickel 212 is also similar to Nickel 200 with manganese addition to improve strength.

Applications

Nickel 211 is used as fuses in light bulbs and grids in vacuum tubes. It is also used in proximity to glass seals because of its enhanced resistance to sulfur based environments.

Nickel 212 is used as fuses for lead-in-wire components in light bulbs. It is also used as lead wires for electrical components and as supporting components in electronic valves and cathode ray tubes. It is also finds use as electrodes in glow discharge lamps.
