Sealer Stable Resistance Fecral Alloy 0cr25al5 Wire Diameter 0.6 -
1.0mm
1. Description and Feature
FeCrAl Alloy, is now the most widely used in electric heating
resistance alloy. With the characteristics of stable performance; anti-oxidation;
corrosion resistance; low expansion coefficient; high temperature
stability; excellent coil-forming ability; high surface load;
uniform and beautiful surface condition without spots.
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: high resistance, low coefficient of electric resistance, High
operating temperature, good corrosion resistance under high
temperature.
Size Available in Stock: 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm

Delivery status and supply state of furnace resistance alloy
heating ribbon
Wire and plate with the looseness or oxidation colour soft modal
supply.
Strip except special requirements outside, general with after
annealing oxidation colour supply.
The flat silk thread and protecting gas to light after annealing
soft modal supply.
2, product packaging of furnace resistance alloy heating ribbon
Wire or strips to pack cloth bandaged volumes supply.
Thread and flat silk, axis encapsulate supply.
3, export products and users have special requirement, negotiation.
Note
1, when the design should be based on the power wiring method,
reasonable surface load, the correct choice of silk diameter,
2, before installation coping furnace thorough examination, cleared
ferritic, "carbon, and the electric stove contact risks to avoid
short circuit, in case caused furnace silk breakdown,
3, when installation should press design wiring method properly
connected;
4, in use before should check the sensitivity of the temperature
control system, in case of failure, cause temperature burnt.
