Description
Copper DP-87 is used: for the manufacture by cold deformation, electrical and electronic structural components (contacts, parts, RF connectors, parts of the waveguide nodes).
Note
The copper powder.
The material should be applied after the impregnation with compounds that protect against internal corrosion. Compositions for the impregnation in accordance with OST 4G 0.054.213.
