Description
Brass ЛП80−78 is used: for the manufacture by the method of single pressing electrical and electronic structural components (contacts, parts, RF connectors, parts of the waveguide nodes).
Note
Brass 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.
