QBe1.7铍铜板#耐磨、 耐低温、无磁性铍青铜
具有较好的流动性和重现精细花纹的能力。由于铍铜合金的诸多X越性能，使其在制造业获得了广泛的应用。
Beryllium bronze introduction: beryllium bronze is a kind of beryllium copper alloy containing (Be0.2 ~ 2.75% wt %), of all the beryllium alloys is a kind of, the use of the most widely used in todays world has been more than beryllium 70% of the total consumption. Beryllium bronze is precipitation hardening alloys, after solid solution aging treatment has high strength, hardness, elastic limit and fatigue limit, elastic hysteresis is small, and a corrosion resistant (beryllium bronze alloy in seawater corrosion speed: (1.1 1.4) x 10-2 mm/year. Corrosion depth (10.9 13.8) x 10-3 mm/year.) After corrosion, beryllium bronze alloy strength, elongation, no change in still water can keep more than 40 years, beryllium copper alloy is a submarine cable repeater constructs an irreplaceable material. In sulfuric acid medium: beryllium bronze (room temperature) in less than 80% concentration of sulfuric acid corrosion depth of 0.0012-0.1175 mm, the concentration of corrosion is greater than 80% is a bit faster.
铍青铜的用途及性能：高性能铍青铜硬度在(HRC)38—43之间，密度8.3g/cm3，含铍1.9%-2.15%，其广泛适用于塑胶注塑成型模具的内镶件、模芯、压铸冲头、热流道冷却系统、导热嘴、吹塑模具的整体型腔、汽车模具、磨耗板等。
铍青铜的铸造工艺及问题：铍铜主要围绕有色金属低压、重力铸造模具使用的各种工况，
