TK 1 Fe-Cr-Al alloy wire rod 0.5mmd
TK 1 (Kan-thal A1 ) 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 deg .
Conventional Product specifications: 0.5 ~ 10 mm
