含钙、硅和铒的无镉银钎料
摘要：
一种含钙、硅和铒的无镉银钎料，属于钎焊材料类，其特征在于，按质量百分数配比是：22.0％～24.0％的Cu，19.0％～23.0％的Zn，14.0％～18.0％的SnIn合金(质量百分数为Sn50％，In50％)，0.1％～0.2％的Ca，0.07％～0.14％的Si，0.03％～0.05％的Er，其余为Ag，其中钙与硅的摩尔比控制在1∶1，钙、硅、铒三元素的加入顺序为先加硅、再加钙、最后加铒。本发明按成分配比，采用中频冶炼炉冶炼、浇铸或水平连铸、挤压、拉拔，即得到所需的钎料丝材。将铸锭先挤压成带材，再经粗轧、精轧，可制备成带材(薄带)。本发明钎料中氧含量低(约在0.002％～0.005％范围，质量百分数)，具有较低的熔化温度、优良的塑性，较BAg40CuZnCd钎料伸长率可提高20.0％～40.0％。
摘要（英）：

The invention provides a cadmium-free silver brazing alloy containing calcium, silicon and erbium and belongs to brazing materials. The cadmium-free silver brazing alloy is characterized by comprising the following components in percentage by mass: 22.0 to 24.0 percent of Cu, 19.0 to 23.0 percent of Zn, 14.0 to 18.0 percent of Sn-In alloy (in mass percentage: 50 percent of Sn and 50 percent of In),0.1 to 0.2 percent of Ca, 0.07 to 0.14 percent of Si, 0.03 to 0.05 percent of Er, and the balance of Ag,, wherein the mole ratio of calcium and silicon is 1:1, and the adding sequence of calcium, silicon and erbium is 1.silicon 2.calcium 3.erbium. In a mixing ratio of the components, the needed brazing wires are formed by the steps of smelting in an intermediate frequency smelting furnace, casting or horizontal continuous casting, extrusion and drawing. The ingots are extruded into strips, and the strips undergo rough rolling and finish rolling to form the thin strips. The cadmium-free silver brazing alloy of the invention is low in oxygen content (nearly in a range of 0.002 to 0.005 mass percent), relatively low in melting temperature, and has good plasticity and a 20.0 to 40.0 percent higher extensibility than the BAg40CuZnCd brazing materials.
