5. corrosion resistance of nickel chrome flat wire Ni80Cr20/NiCr8020 heating resistance wire
Introduction:
1. Nichrome flat wire is a type of heating element wire that is commonly used in various applications such as in heaters, ovens, toasters, and other electrical appliances. It is made of an alloy of nickel and chromium, which provides high resistance to electrical current and excellent heat resistance. The flat shape of the wire allows for efficient heat transfer and distribution. Nichrome flat wire is known for its durability, stability at high temperatures, and consistent performance, making it a popular choice in the heating industry.
2.mechanical properties of Nichrome flat wire:
Tensile Strength: Typically ranges from 600 to 900 MPa.
Yield Strength: Around 275 to 550 MPa.
Elongation: Generally between 20% to 35%.
Hardness: Varies depending on the specific alloy composition.
These properties can vary based on the specific grade and manufacturer of the Nichrome flat wire.
3.Corrosion Resistance: Nichrome wire is resistant to oxidation and corrosion, ensuring a longer lifespan in various heating applications.
4. Fast Heating: Due to its high resistance, Nichrome wire heats up quickly, providing rapid heat generation in heating devices.
5. Durable: Nichrome wire is durable and can withstand repeated heating cycles without significant degradation in performance.
