硬质铍铜【QBe1.7铍铜棒】QBe1.7铍铜棒
Beryllium bronze is a contain beryllium copper base alloy (Be0.2 ~ 2.75% wt %) of all the beryllium alloy 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.
铍青铜是一种含铍基铜合金（Be0.2～2.75%wt%）在所有的铍合金中是用途X广的一种，其用量在当今世界已X过铍消费总量的70%。铍青铜是沉淀硬化型合金，固溶时效处理后具有很高强度、硬度、弹性极限和疲劳极限，弹性滞后小，并具有耐蚀（铍青铜合金在海水中耐蚀速度：（1.1-1.4）×10-2mm/年。腐蚀深度：（10.9-13.8）×10-3mm/年。）腐蚀后，铍青铜合金强度、延伸率均无变化，故在还水中可保持40年以上，铍铜合金是海底电缆中继器构造体不可替代的材料。在硫酸介质中：铍青铜在小于80%浓度的硫酸中（室温）年腐蚀深度为0.0012-0.1175mm，浓度大于80%则腐蚀稍加快。
性能：耐磨、耐低温、无磁性、高的导电性、冲击无火花等特点。同时还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。
