MATERIAL: This heating coil is made of FeCrAl heating alloy, which has high temperature resistance, good thermal efficiency, uniform heating and safe use. It also has good wear resistance and rust resistance and can be used for a long time. OPERATION: Durable heating coils should be stretched to at least twice their original length when in use (theoretically, the longer they are stretched, the longer they will last), please stretch these heating componentcoils before connecting to power, otherwise they will burn and cause damage. APPLICATION: Heat resistant coils are heating component coils for kilns for pottery, metal casting, heat treatment, forging and many other purposes, widely used in small electric furnaces, heating and air conditioning equipment, bakeries, electric heating pipes, household appliances, etc. PARAMETERS: The outer diameter of the furnace wire of the practical coil is 5.6mm, the length of the furnace wire is 474mm, its applicable voltage is AC 220V, and the power is 1200W. There are a total of 3 heating coils in our package to meet your different needs. TIP: It cannot be cut into parts for use, otherwise the power will be increased, so as not to cause safety problems.
