0cr21al4 Fecral Alloy Ribbon / Flat Wire No Burr For Mica Heater Elements
FeCrAl alloy usually has high electrical resistivity, temperature coefficient of resistance is small, high operating
temperature. good corrosion resistance under high temperature, and particularly suitable for use in a gas containing sulfur and sulfides, low price,
it is widely used in industrial electric furnace, household appliances, far infrared device ideal heating material.
FeCrAl resisance alloy wire
1. A quite reasonable price
2. heating resistance wire Stable performance: high working temperature(The highest temperature can be 1400 C ), high strength under temperature, corrosion resistance, long life-span, allowable high surface load, small specific gravity, good formability and weldability.
Delivery status and supply state
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.
1. Wire or strips to pack cloth bandaged volumes supply.
2. Thread and flat silk, axis encapsulate supply.
3. export products and users have special requirement, negotiation.
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 heating resistance wire 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.
