Chromium Powdered Bronze CuCr2-PM

To outfit vacuum arc-quenching chambers, parts made of powdered bronze are also used, with an increased softening temperature (more than 100 ^оС in comparison with cast chromous CuCr0.7 and chromium-zirconia  CuCrZr bronzes), alloyed with 2% chromium: CuCr2-PM with diameters of 48, 56, 66, 80, et al. Conductivity is at least 85%, and hardness at least 115 HB.

Typical properties:

- density 8.86-8.88 g/cm³,

- conductivity 87-92%,

- hardness 130-140 НВ.

Chromous dispersion-reinforced CuCr2-PM bronze in the form of discs with diameters of up to 300 mm are also applied as electrodes for resistance-seam welding of carbonous and low-alloyed steels. Electrodes made from thermomechanically treated CuCr2-PM bronze are distinguished from traditional CuCr1 bronze by increased hardness, resistance to setting and service durability under contact sealing.
