Supplier KMZ offers to buy a circle, a wire, a tube made of chromium-zirconium and chromium-titanium-zirconium bronzes Brcr and Brkcrt at economical price. The provider ensures timely delivery of products at any Price the best in this segment of the rental.

Technical characteristics

Chromium-zirconium and chromium-titanium-zirconium bronze represent the copper alloys with high heat resistance. They are characterized by high strength and resistance from exposure to alternating loads, are used in power electronics, aviation, industrial construction, and also in the manufacture of bearing rings from slipping. The presence of zirconium in the composition of bronze reduces the conductivity. Specific industry use of these alloys — manufacture of stringed musical instruments. The addition of Zirconia, which has high strength and workability provides a significant increase in acoustic characteristics while the simultaneous addition of titanium contributes to the increasing share of the higher harmonic component in the sound, and improve the audibility of sound.
