Production of pseudo-alloys
Copper-molybdenum pseudo-alloy MD-40 contains Cu — 40%, Mo — up to 60%, impurities less than 0,04%. МD-50 contains Cu-50%, Mo-50%, impurities 0,04% and less.

Manufactured parts should be free of delamination, cracks, tears on the edges and foreign inclusions. The starting material for the production of stacks, and later ribbons and sheets, are: copper electrolytic powder of PMS-1 grade (GOST 4960), nickel powder of PNK-1L6, PNK-1L5 grade (GOST 9722), high-purity molybdenum metal powder according to TU 48−19−69−80, MHR grade or reduced molybdenum powder according to TU 14−22−160−2002.
Basic qualities
Relatively low density, excellent thermal conductivity, high tightness. Copper-molybdenum pseudo-alloys allow to produce products with unique consumer characteristics — wear-resistant, heat-resistant, with high damping qualities, low friction coefficient and self-lubricating ability. Specific thermal conductivity and electrical conductivity of alloys depend on the ratio of the main components of the alloy and the residual porosity.
Use
Production of metal-oxide semiconductors with surface diffusion, field-effect transistors for millimeter and ultrahigh frequencies and heterotransistors, bipolar devices, microwave integrated circuits, power supplies, containers for optoelectronics and packaging of laser diodes. Pseudo-alloys are used as billets to produce strips and sheets by rolling and to manufacture various parts. Copper-molybdenum pseudo-alloys MD-40 and MD-50 are designed for production of articles with increased thermal conductivity, as well as for soldering with beryllium and alumina ceramics. Compared with copper-tungsten, copper-molybdenum pseudo-alloys are much lighter, so they are used in those products where low weight is important. Sheets containing up to 70% molybdenum are used for stamping.
