The electric heating strip is used in electric blanket,hair dryer,rice cookers,electric kettle,electric ceramic cooktop etc.

With good  cold forming ,small resistance fluctuation, uniform heating.Due to the addition of special trace elements,

it is advantageous to  form  a compact oxide film with substrate temperature in the heating process,to improve the

creep resistance.
