Cr20Ni80 is an ideal material with good ductility under high temperature and seismic strength. It is not easy to deform under high temperature use, its structure is not easy to change, and it has good processability and weldability. Nickel-chromium and nickel-chromium iron alloys are the most widely used high-resistance electric heating alloys. They have high and stable resistance, corrosion resistance, high temperature resistance and oxidation resistance, good flexibility, good plasticity after long-term use, and easy repair. The same type of The permanent elongation is very small, its emissivity is high, it is non-magnetic, and it has excellent comprehensive properties. It is the first choice for producing high-quality electrical components. It is a high-resistance nickel-chromium alloy used in resistance heating elements. It forms an attached layer of chromium oxide when heated for the first time. The material under the wire will not oxidize, preventing the wire from breaking or burning out.
These components are often used in precision heating fields such as medical diagnostics, satellites and aerospace, electrical appliance industry, ironing machines, water heaters, plastic molding molds, soldering irons, metal sleeve components, cartridge components.
How about the nichrome strip working performance in furnace heating project?
Nichrome strips are widely used in furnace heating applications due to their excellent performance and advantages. Here are some key points about the working performance of nichrome strips in furnace heating projects:
1. High-Temperature Resistance:
Nichrome has a high melting point (around 1400°C) and can withstand prolonged exposure to high temperatures inside furnaces without degrading or losing its properties.
2. Oxidation Resistance:
The chromium content in nichrome makes it highly resistant to oxidation, which is crucial in furnace environments where the heating elements are exposed to high temperatures and oxygen.
3. Durability and Long Lifespan:
Nichrome strips have a long service life and can operate reliably for extended periods in furnace heating applications, minimizing the need for frequent replacements.
4. Efficient Heat Generation:
The high electrical resistance of nichrome allows it to generate heat efficiently when an electric current is passed through the strips, making it an effective heating element.
5. Precise Temperature Control:
The consistent and predictable heating characteristics of nichrome strips enable precise temperature control in furnace heating systems, which is crucial for many industrial and manufacturing processes.
6. Easy Integration:
Nichrome strips can be easily integrated into various furnace designs and heating systems, providing flexibility in the design and installation of the heating elements.
7. Cost-Effectiveness:
Compared to some other high-temperature heating materials, nichrome is relatively cost-effective, making it a popular choice for furnace heating applications.
