Cr20Ni80 characteristics:
High electrical resistivity: Nichrome cr20ni80 has a relatively high electrical resistivity, typically around 1.08-1.13 Ω·mm²/m, which makes it suitable for manufacturing heating elements.
High-temperature endurance: This alloy can be used for long-term operation at temperatures below 800°C, with good high-temperature performance.
Oxidation resistance: The high Cr content provides Nichrome cr20ni80 with good oxidation resistance. It can be used in air for an extended period without rapid oxidation.
Good workability: Nichrome cr20ni80 is soft and easy to process into various shapes of heating elements.
Make heating elements with cr20ni80 wire:
Here are the general steps to use Nichrome Cr20Ni80 wire to make heating elements:
Determine the heating requirements:
Calculate the desired wattage, resistance, and operating voltage for the heating application. Select the appropriate Cr20Ni80 wire gauge and length based on the power and resistance needs.
Form the heating element shape:
Bend or coil the Cr20Ni80 wire into the desired shape, such as a spiral, zigzag, or straight configuration. Use jigs or fixtures to maintain the uniform spacing and shape of the wire.
Install insulation:
Wrap the formed Cr20Ni80 wire with high-temperature insulating materials, such as ceramic fiber, mica, or fiberglass. This insulation helps to electrically isolate the heating element and protect it from the environment.
Secure the heating element:
Mount the insulated Cr20Ni80 heating element onto a suitable frame or support structure.Use high-temperature adhesives, clamps, or fasteners to firmly hold the heating element in place.
Provide electrical connections:
Attach electrical lead wires to the ends of the Cr20Ni80 heating element. Ensure secure and reliable connections, often using crimping or welding techniques.
Enclosure and housing:
Enclose the heating element assembly within a protective housing or casing, if required by the application.This helps to shield the heating element and provide a safe, controlled environment.
Testing and quality control:
Carefully test the heating element for proper resistance, wattage output, and overall functionality. Inspect the assembly for any signs of damage or defects before final installation.
