Description

Nickel-chromium can be made into alloy nickel-chromium wire with elements such as iron, aluminum, silicon, carbon and sulfur, which has the advantages of high temperature resistance, high strength, strong plasticity, high resistivity and heat resistance. Nickel-chromium alloy wire is the most fundamental component of most heating elements and is widely used in electric heaters, silicone rubber heating pads, mica heating coils, and hot runners.

The coil generally used in a sliding rheostat has the function of maintaining the circuit and modifying the resistance of the part connected to the circuit to change the current in the circuit, and thereby altering the voltage across the series conductors (electrical appliances).

Mechanical properties of pure nickel wire is close to carbon steel, its alkaline corrosion resistance in metal materials only second to silver, nickel wire in concentrated alkali surface will generate a layer of black protective film. Makes it very corrosion resistant. Used for electric light source materials, coating, with high surface quality, good processing performance, used for making work such as anode, partition, electrode bracket, etc., can also be used as a guide wire in the bulb, in addition to the chlor-alkali industry,nickel wire has played a very important role.

The mechanical properties of nickel are close to carbon steel, and its alkaline corrosion resistance is second only to silver in the metal materials. The surface of φ 0.025mm nickel chrome resistance wire will generate a layer of black protective film in concentrated alkaline. Makes it very corrosion resistant.

φ0.025mm nickel chrome resistance wire is used for electric light source materials, coating, with high surface quality, good processing performance, used for making work such as anode, partition, electrode bracket, etc., can also be used as a guide wire in the bulb, in addition to the chlor-alkali industry has played a very important role. Electrical grade materials because of the use of different conditions, and a variety of components of the alloy. Moreover, the electrode materials are required to have low resistivity to avoid overheating of the electrode, high high-temperature strength to reduce material wear, and sticky melting and volatilization to improve service life under the action of arc.

As we know ,the heating function of the heating element is achieved by the resistance wire.So the quality of the heating resistance wire determine the heater element's level.

So let us see the factors which resistance wire should required:

1.Adequate heat resistance, that is, no or little oxidation at high temperatures;

2.The lower the resistivity, the better;

3.Working for a long time without aging;

4.Good processing performance, can be processed into linear, ribbon or spiral, and has good welding performance;

5.It has certain mechanical strength at high temperature;

Characteristics

1, with weldability, high electrical conductivity, suitable linear expansion coefficient;

2, good strength at high temperature, low resistivity;

3, high melting point, corrosion resistance, good mechanical properties, in hot and cold state have good pressure workability, easy to degassing, suitable for radio, electric light source, mechanical manufacturing, chemical industry, is an important structural material in vacuum electronic devices.
