Alchrome 875 FeCrAl alloy wireAlchrome 875 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 .
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.
