Domestic chromium bronze brand mainly QCr0.5, QCr0. 5-0. 2-0.1, QCr0. 6-0. 4-0. 05, etc., in the American ASTM standard chromium bronze brand is more, have C18150, C18200, C18400, C18500, etc. Chrome bronze is containing 0. 4% ~ 1.1% Cr (mass fraction, below are the same as) the high copper Cu - Cr alloy binary phase diagram shown in figure 1-12. Under the eutectic temperature 1072 ℃, the maximum of chromium in copper solubility for 0. 65% (literature thought 0.68%). Solid solubility fell sharply with the decrease of temperature, and aging treatment after solid solution precipitation Cr phase particles. Chromium bronze by quenching, aging or quenching a cold deformation, aging treatment for reinforcement. Chromium to join, on the one hand, obviously improve the alloys recrystallization temperature and heat intensity; On the other hand makes the conductivity of copper declined slightly. Solid solution treatment of chromium bronze bar conductivity 80% IACS, up to 80% IACS after aging treatment. Ageing of the chromium bronze softening temperature is 400 ℃, is cold, twice of the copper. This alloy can be used in the casting state and deformation state. Al and Mg as chrome green
