TK D 0Cr23Al5 FeCrAl Alloy Electric Resistance Round Wire Flat Wire Ribbon Wire In Stock
Tankii's Resistance wire is used to control the amount of current in a circuit.
High resistivity is better since a shorter wire can then be used.
When the stability of the resistor is of primary importance the alloy’s temperature coefficient of resistivity and corrosion resistance are very important in material selection.
When it is used for heating elements for applications such as electric heaters and toasters,high resistivity and oxidation resistance is important.
Shanghai Tankii Alloy Material Co., Ltd. specialized in production of Resistance Heating Alloy, Nickel Chromium Alloy, Iron Chromium Aluminum Alloy, Nickel Aluminum Alloy, Manganin, Copper Nickel Alloy, thermocouple wire, pure nickel and other precision alloy materials in the form of round wire, ribbon wire, sheet, tape, strip, rod and plate.
