Nichrome is a special nickel and chromium alloy, which have stable structure and electrical physical performance, in addition, good high temperature mechanical property, fine cold plastic deformation and weldability, as a result of which, it cannot have the brittle fracture due to long-term use. The alloy is widely used in manufacturing the household appliances and heating element below the working temperature of 1000℃. Its service life is long. Because of high nickel quantity, the price is high.
