Resistohm 145 / 0cr21al6nb / HN A1 A-1 Resistance Heating Wire on Resistance Furnace
Resisohm 145A1 large-sized cold-drawn wire products can be used for
high-temperature resistance furnace. Practice has proved that: the
product process is stable, integrated performance is good. Has good
high temperature oxidation resistance and longer service life;
excellent winding properties at room temperature processing, ease
of processing molding; little rebound resilience and so on.
Processing performance is very good; operating temperature can
reach 1400 ºC.
Main specifications and uses:
Conventional Product specifications: 0.5 ~ 10 mm
Uses: mainly used in powder metallurgy furnace, diffusion furnace,
radiant tube heater and all kinds of high-temperature furnace
heating body.
