Electric heating element resistance wire
1.WHY CHOOSE WISDOM FECRAL HIGH QUALITY RESISTANCE HEATING ALLOYS
Wisdom manufacturing unit possesses a fully integrated production infrastructure starting from melting of virgin raw materials to final packaging stage.
In the market, not all the FeCrAl alloys are with standard chemical composition and stable resistance Professional and reliable is the soul of our business.
2.DE
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
3.WISDOM 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.
