Nichrome A (or NiCrA)
Nichrome A (or NiCrA) is and alloy that contains contains:
80% Nickel and 20% Chromium
Nikrothal
Nikrothal is registered trademark of Sandvik of Sweden. Nikrothal forms a range of austenitic nickel-chromium alloys (NiCr alloy) for use at temperatures from approximately 1050°C (1920°F) to 1200°C (2190°F). The alloy is characterized by high resistivity and moderate oxidation resistance. It has good ductility after use and excellent weldability.
The Nikrothal range (Nikrothal 20 to Nikrothal 80) contains various mixes of:
Nickel (Ni) Chromium (Cr) Silicon (Si) Iron (Fe) and trace amounts of carbon (C).
Chromel
Chromel is an alloy made of approximately 90 percent nickel and 10 percent chromium that is used to make the positive conductors of ANSI Type E (chromel-constantan) and type K (chromel-alumel) thermocouples. It can be used up to 1100 °C in oxidizing atmospheres. Chromel is a registered trademark of the Hoskins Manufacturing Company.
Chromel A
Chromel A is an alloy containing 80% of nickel and 20% chromium (by weight). It is generally used for its excellent resistance to high-temperature corrosion and oxidation. It is also commonly called Nichrome 80-20 and used for electric heating elements.
Chromel C
Chromel C is an alloy containing 60% nickel, 16% chromium, and 24% iron. It is also commonly called Nichrome 60 and is used for heating elements, resistance windings, and hot wire cutters.
