High Temperature Electric Resistance Cr20Ni35 Furnace Heating Wire For Chemical Industry

Cr20Ni35 is a common nickel-chromium alloy heating wire, which is widely used in various heating equipment and fields. It is composed of approximately 20% chromium (Cr) and 35% nickel (Ni) and has good resistance characteristics and high temperature stability.

Cr20Ni35 heating wire is suitable for household appliances, industrial heating equipment, laboratory equipment and other fields. It can generate high temperatures quickly and has stable heating performance. The maximum operating temperature can reach 1100-1200 degrees Celsius, which is suitable for applications requiring high temperature heating.

The heating wire has moderate resistivity and can effectively convert electrical energy into heat energy. It also has a low coefficient of linear expansion and good mechanical strength, allowing it to maintain stability and reliability under high temperatures and mechanical stress.

Cr20Ni35 heating wires are available in a wide range of diameters, and the appropriate diameter can be selected according to the needs of the specific application. It is widely used in various heating systems such as electric water heaters, ovens, dryers, and laboratory heating equipment.
