无铅易切削高导电率的钙碲青铜材料
摘要：
本发明公开一种无铅易切削高导电率的钙碲青铜材料，其特征在于：该材料的重量百分比组成为：Ca 0.1～1.0％、Te 0.05～0.4％、镧铈合金0.01～0.1％、P 0.002～0.015％、Mg 0.002～0.012％、Pb＜0.01％(含量可以为0)，余量为铜和总量不大于0.04％的杂质，且满足Cu+Ca+Te＞99.90％、Cu+Ca+Te+P+Mg+镧铈合金＞99.96％。本发明具有良好的导电率、良好的灭弧性能和良好的切削加工性能，而且可以退火处理且可焊性能好的优点。
摘要（英）：

The invention discloses a lead-free free-cutting high-conductivity calcium tellurium bronze material. The lead-free free-cutting high-conductivity calcium tellurium bronze material is characterized in that the material is prepared from the following components by weight percent: 0.1 to 1.0% of Ca, 0.05 to 0.4% of Te, 0.01 to 0.1% of lanthanum cerium alloy, 0.002 to 0.015% of P, 0.002 to 0.012% of Mg, less than 0.01% of Pb (the content can be 0) and the balance of copper and impurities of which the total quantity is not greater than 0.04%, wherein Cu+Ca+Te is greater than 99.90%, and Cu+Ca+Te+P+Mg+lanthanum cerium alloy is greater than 99.96%. The lead-free free-cutting high-conductivity calcium tellurium bronze material has the advantages of good conductivity, good arc extinguishing performance, good machinability and good weldability, and annealing treatment can be performed.
