FeCrAl Alloy 8mm 10mm 12mm 14mm Rod / bar Used For Heater Leading Rod
Tankii DESCRIPTION OF FECRAL ALLOYS:
FeCrAl alloys are characterized by excellent oxidation resistance and very good form stability resulting in long element life.
They are typically used in electrical heating elements in industrial furnaces and home appliances.
FeCrAl alloys have higher service temperature than NiCr Alloys and much lower prices. But they have lower stability and flexibility, easily to be fragile after a time circle
Special Application in high temperature furnace/ annealing furnace
1. Wire connecting
2. Wire lead-out
TANKII FECRAL ALLOYS CHARACTERISTICS:
1) Manufactured according to international quality. System (ISO9001).
2) Stable resistance and long-life span.
3) Mill test certificate will be provided after production.
4) Size range wire:.0.018-10mm ribbons: 0.05-0.2*2-6mm strips: 0.05-5*5-250mm.
5) Good packing methods to keep goods no damage during delivery.
6) Customized lable, packing, OEM service..
7) 24 hours after-sale service.
