Description

Brass ЛП80−84 is used: for the manufacture by cold deformation, 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.
