Product Description
- Cr20ni30 Heating Resistance Wire
Ni30Cr20 is an austenitic nickel-chromium alloy suitable for temperature applications up to 1100°C. This alloy is characterized by high resistivity, good oxidation resistance, good ductility after use and excellent weldability. Ni35Cr20 is used for a wide range of electric heating elements in domestic appliances.
- Electric Furnace Heating Elements
Cr20Ni30 resistance wire is widely used in manufacturing electric furnace heating elements such as furnace wires and heaters. It can work stably at high temperatures and provide uniform heat output, making it suitable for melting metals or heating other materials.
- Home Appliances
Cr20Ni30 resistance wire is used to manufacture electric heating elements in home appliances such as electric kettles, electric ovens, and electric blankets. These elements can maintain stable temperature and power output over extended periods.
- Industrial Heaters
Cr20Ni30 resistance wire is used in industrial heaters such as hot air guns and heating plates. They are used in industrial production to heat liquids, gases, or solid materials and offer a long service life and corrosion resistance.
- Specialized Heating Equipment
Cr20Ni30 resistance wire can also be used in specialized heating equipment such as hot water boilers and industrial ovens. These devices require precise temperature control within different temperature ranges, and Cr20Ni30 resistance wire can meet these requirements.
