Nickel Chromium Alloy Powder
Nichrome (NiCr), nickel-chrome, chrome-nickel is any various alloys of nickel, chromium. Nichrome alloys are known for their high mechanical strength and their high creep strength. The properties of nichrome vary depending on its alloy. Its melting point is 1400℃ and has a density of 8.9 g/cm3. Also, it has 480-550 MPa tensile strength. A range of commercial alloys is based on this solid solution. Such alloys have excellent resistance to high temperature oxidation and corrosion and good wear resistance. Nickel-chrome alloy powders are generally used in oxidation resistance, heating elements, thermocouples, high temperature corrosion resistant alloys, wear resistant alloys. Nichrome powder is used in the explosives and fireworks industry as a bridgewire in electric ignition systems, such as electric matches and model rocket igniters. Nichrome wires made from these powders can be used as an alternative to platinum wire for flame testing by coloring the non-luminous part of a flame to detect cations such as sodium, potassium, copper, calcium, etc.
