Description
Alloy MS-ING used: for the manufacture of wire And groups (from 15 to 150 microns), G (20 to 200 µm) and E (50 to 200 µm) by powder metallurgy, intended for the manufacture of grids for electronic devices.
Note
Group a: Wire, having on the surface layer of the technological lubricant. Color from black to dark gray.
Group G: Wire, free from technological lubricant by electrochemical etching method and otogenny the required mechanical properties.
Group E: Wire, free from technological lubricant by electrochemical etching method and ataegina low plasticity.
