Cr20Ni80 alloy wire is an alloy wire composed of elements such as chromium (Cr) and nickel (Ni). Its chemical composition is 20% chromium and 80% nickel. It is a common resistance alloy, also known as nickel-chromium alloy (Nichrome).

1. Physical properties: Cr20Ni80 alloy wire has a high melting point, about 1400 degrees Celsius. Its density is about 8.4 g/cm3 and it has good mechanical properties and thermal conductivity.

2. Resistance properties: The resistance of Cr20Ni80 alloy wire is relatively stable with temperature changes and has a small temperature coefficient. This means that within a certain temperature range, its resistance value changes less, can provide reliable heating effect, and facilitate temperature control.

3. High temperature stability: Cr20Ni80 alloy wire shows good stability in high temperature environments and is not prone to deformation or oxidation. This makes it suitable for applications requiring high temperature heating, such as ovens, electric stoves, etc.

4. High resistivity: Cr20Ni80 alloy wire has a high resistivity and has a stronger resistance to current than other alloy wires. The high resistivity enables the Cr20Ni80 alloy wire to generate greater heat when passing current, achieving an effective resistance heating effect.

5. Corrosion resistance: Cr20Ni80 alloy wire has certain resistance to oxidation and corrosion, and can form a dense oxide surface layer in an oxidizing environment to prevent further oxidation and corrosion.
