monel（蒙奈尔）的力学性能如何？

nel1982

只知道monel（蒙奈尔）是一种合金，可以抵抗腐蚀，可以和不锈钢相媲美，但不知道他的性能怎么样，还请各位大虾大显身手哦！！谢谢！！ :handshake

Monel is an alloy [size=-1](i.e. combination of two or more elements of which at least one is a metal, and where the resultant material has metallic properties). It is based on nickel (65-70%) and copper (20-29%) and also contains iron and manganese (5%) and other compounds. Monel was discovered by Robert Crooks Stanley who worked for the International Nickel Company (INCO) in 1901. The new alloy was named in honor of the president of the company, Ambrose Monell.
[size=-1]Monel is a trademark of Special Metals Corporation

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.

- Malleable
- Low coefficient of thermal expansion
- Highly resistant to alkalis
- It can be welded, brazed and soldered
