Resistance Wire for Water Heater

Nichrome Water Heater Wire is a name for a Nickel-Chromium Water Heater Wire. It is corrosion resistant, and has a high melting point of about 1400 °C (2552 °F). Nichrome Water Heater Wire has high resistivity and very good resistance to oxidation at high temperatures. The ultimate tensile strength of the wireis 105,000 PSI (Pounds per Square Inch), yield strength is around 50,000 PSI, and modulus of elasticity is 31 x 106 PSI.

Nichrome Water Heater Wires have many advantages, such as deformation ability, thermal stability, mechanical character, shockproof ability in thermal state and anti-oxidization. For heating, Resistance Wire must be stable in air when hot. The wire forms a protective layer of chromium oxide. Due to its relatively high resistivity and resistance to oxidation at high temperatures.

Nichrome Water Heater Wire is widely used in heating elements, electric furnace heating and heat-treating processes in the chemical, mechanical, metallurgical and defense industries, tube heater, and boiler. Typically, Nichrome Water Heater Wire is wound in coils to a certain Heat resistance, and current passed through to produce heat. They are also used as material of industrial equipment and Heat resistant elements in the electronics and light textile industries.

Nichrome Water Heater Wire is an ideal material, because it has relatively high resistance and forms an adherent layer of chromium oxide when it is heated for the first time. Material beneath the Resistance Wire will not oxidize, preventing the Resistance Wire from breaking or burning out. So it is good for anti-corrosion and high resistant co-efficiency.

FeCrAl High Resistance Wire has high resistance, low temperature coefficient of electric resistance, high operating temperature, and good corrosion resistance under high temperature, especially under the atmosphere containing sulfides. It posses good oxidation and heat resistance.FeCrAl High Resistance Wires are creep-resistant over a wide range of temperature, which is another of their important qualities.

FeCrAl High Resistance Wire has several potential advantages, such as lower raw-material cost, superior oxidation resistance, lower density, and lower thermal expansion coefficient than the Ni-base super-alloys.

However, it has less hot strength than nickel s but much higher melting point and lower price. After being heated the Resistance Wire's plasticity becomes bad, easy brittleness, not to be easy to weld. However, If can be reasonably used, also be a kind of ideal electric heating material.

FeCrAl High Resistance Wires are made of iron chromium aluminum base s containing small amounts of reactive elements such as yttrium and zirconium. The high aluminum content, in combination with the high chromium content causes the scaling temperature to increase up to 1425 C (2600F ); FeCrAl Heat Resistance Resistance Wire s also have excellent oxidation properties at 800-1300° C because of the formation of a highly protective Al2O3 scale.
