Copper contacts are manufactured from pure copper powder with a density approaching that of compact material and with specified surface geometry. These contacts can subsequently be electroplated with silver, tin, bismuth, and other metals.

For the production of contacts for high-power circuit breakers, a composite based on refractory metals impregnated with copper or silver, similar to the MB-70 type, is used.

Sliding contacts or current collectors are made from a composite based on a wear-resistant conductive material with the addition of antifriction conductive additives such as graphite or MoS2. The basis of these materials is dispersion-strengthened copper reinforced with Al2O3 particles or chromium carbide, with particle sizes ranging from 0.5 to 1 µm.

In the production of cores, we use powders from the Swedish company Hoganas, which ensures consistent product properties, and the implementation of sintering technology in a decarburizing environment has allowed us to achieve consistently high soft magnetic properties.
