Atomized iron powder
Application:
- in production of powder parts for antifriction, construction and electro technical purposes, sintered electrode tape, frictional disks;
- in flux-oxygen cutting of metals, as a basic component of high- production electrodes
- in production of printing inks, as a catalyst and reducing agent of different chemical production, in magnetic flaw detection.
Iron powder is produced by means of spraying molten metal by high-pressure water of such grades: ПЖР 3.200.28-30, ПЖР 3.315. 26-28, ПЖР 3.450.28-30.
Technical specifications: ГОСТ 9849-86 "Порошок железный" with modifications №1,2.
