The chemical composition of bronze GOST 18175−78 and the 48−21−222−72
- Cubic Zirconia, % — 0,8.1,2;
- Titanium (only for grade Brkcrt), % — 0,5…0,8;
- Other impurities (iron, aluminum), % — not more than 0.3.
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.
- Melting point, °C — 1065;
- Density, kg/m3 — 8830;
- Coefficient of thermal expansion, µm/deg in the temperature range 20…300°C — 17,9;
- Coefficient of thermal conductivity after quenching and aging, W/mgrad — 335.
- The limit of temporary resistance, MPa — 535 580…(a smaller value corresponds to the bronze Brcr);
- Yield stress, MPa 480;
- Elongation, % — 5;
- The Vickers hardness, HV, of not more than — 154.
Dispersion hardening occurs in the temperature range 300…500°C. the Machinability is satisfactory, the Temperature range for forging is 800 to 850 °C.
