Chromel

Chromel is a chromium -nickel alloy, mainly for the production of thermocouples American standards, especially ANSI Type K ( chromel - alumel ), and E ( chromel - constantan ) used. Chromel alloys consist of about 90 % nickel and 10 % chromium. Chromel is a registered trademark of Concept Alloys Inc (formerly Hoskins Manufacturing Company) ..

Chromel can be used up to 1100 ° C in oxidative environments and its melting point is 1420 ° C. Its specific resistance is 0.706 μΩ · m.

Modifications

• A Chromel is an alloy of 80 weight percent nickel and 20 % chromium, with very good temperature resistance. Chromel A is also marketed under the name Nichrome 80-20 and used as a heat conductor.
• Chromel C or nichrome 60 is an alloy of 60% nickel, 16 % chromium and 24 % iron. Chromel C is also used as a heat conductor, as well as for wire resistors and thermal cutting.
