Was created by David H. Browne - chief metallurgist at the International Nickel Company - and patented in 1906. |
The new alloy was named in honor of the company's president, Ambrose Monell, but the 'L' was dropped because at the time, surnames were not allowed as trademarks. There are different commercial types of Monel such as: Alloy 400, Alloy 401, Alloy R-405, Alloy 450, Alloy K-500, Monel 404 Copper-Nickel Alloy. Standard product forms are round, hexagon, flats, forging stock, pipe, tube, plate, sheet, strip, and wire.
Nowadays MONEL is a trademark ofSpecial Metals Corporation, USA.
MONEL'S MAIN CHARACTERISTICS AND PARTICULARITIES
- Highly resistant to corrosion. Monel is well known for corrosion strong, rust-resistant material. It is resistant to corrosion and acids, and some alloys can withstand a fire in pure oxygen...
- Stronger than steel, but is typically much more expensive because of the Nickel used - a basic compound in the alloy...
- Moldable...
- Low coefficient of thermal expansion...
- Highly resistant to alkalis...
- It can be welded, brazed, and soldered.
MONEL ● INDUSRTRY APPLICATIONS
MONEL® is used for marine (underwater parts) and aerospace engineering (hi-thermal insulation), chemical and hydrocarbon processing equipment, valves, shaft pumps, fittings, fasteners, heat exchangers. It is also used for making optical frames, for some metal parts of musical instruments, and for many others.
