0Cr21Al4 FeCrAl Alloy Electric Wire/ Coil with Dia 5mm for Heating Equipment
Product Description:
With the characteristics of high resistance, low coefficient of electric resistance, High operating temperature, good corrosion resistance under high temperature.
It is mainly used in electric locomotive, diesel locomotive, metro vehicle and high Speed moving car etc
brake system brake resistor, electric ceramic cooktop, industrial furnace.
Feature:
With long service life.Heating up fast.High thermal efficiency.Temperature uniformity. Can use vertically. When being used in the rated voltage,there is no volatile matter.It i the ne environmental protection electric heating wire.And an alternative to the costly nichrome wire.Can be customized according to customer requirements
Usage:
It is widely used in industrial furnace, household electrical appliances, infrared heater, etc.
The key properties:
1.The thickness of surface insulation resistance to oxidation layer: 5-15 μ m.
2. Insulation resistance: multimeter detection infinity.
3.The voltage-endurance of insulating single layer is greater than the alternating voltage 60 ν without breakdown.
4. The use of voltage: 6-380 ν.
5. Using temperature: Maximum1200 ºC
6. Service life: not less than 6000 hours.
7.Thermal shock performance: Electric heating element can withstand the cold and hot impact 600-6000 times without deformation.
