Tungsten –Copper alloy is the composite of Tungsten and Copper which own the excellent performances of Tungsten and Copper, such as heat-resistant, ablate-resistant, high-intensity,high-density, excellent thermal and electrical conductivity. It is easy to be machined. It is used widely in such industries as engine, electric power, electron, metallurgy, spaceflight and avigation.

钨铜材料是钨和铜的一种合金，综合了钨和铜的优点，耐高温、耐电弧烧蚀、强度高、比重大、导电、导热性好，易于切削加工，并具有发汗冷却特性，作为真空触头材料、电极材料、电子封装材料以及火箭、导弹特殊用途材料等广泛应用于机械、电力、电子、冶金、航空航天等工业。

And a chapiter of brass was upon it; and the height of one chapiter was five cubits, with network and pomegranates upon the chapiters round about, all of brass.

52：22 柱上有铜顶，高五肘。铜顶的周围有网子和石榴，都是铜的。

The height of the one pillar was eighteen cubits, and the chapiter upon it was brass: and the height of the chapiter three cubits; and the wreathen work, and pomegranates upon the chapiter round about, all of brass: and like unto these had the second pillar with wreathen work.

25：17 这一根柱子高十八肘，柱上有铜顶，高三肘。铜顶的周围有网子和石榴，都是铜的。那一根柱子，照此一样，也有网子。

However, the quality of the copper film deposited by this method is poor. In order to resolve this problem, we study the influence of some additives on two different kinds of electroless copper plating which using sodium hypophosphite as reducing agent and sodium citrate as chelating agent, sodium citrate and ethylene diamine tetraacetic acid disodium salt (EDTA·2Na). Electrochemical methods were used to test the anodic and cathodal polarization processes which can explain the mechanism of the influence of additives.

然而该体系所得的铜膜质量较差，为此我们研究了以次磷酸钠为还原剂，分别以柠檬酸钠为单一络合剂，柠檬酸钠和乙二胺四乙酸二钠为双络合剂体系中，研究了几种添加剂对化学镀铜的影响，并通过电化学方法研究了各种添加剂对化学镀铜沉积电位的影响。

The results of FTIR and QCM measurement showed that Schiff bases could chemisorb on the copper surface through coordination, indicating that it is feasible to prepare SAMs of Schiff bases on the copper surface.

QCM和FTIR结果表明，希夫碱分子通过其中的亚胺基与铜的配位作用在铜表面发生化学吸附，从而形成自组装膜。因此用自组装技术在铜表面上制备希夫碱自组装膜是可行的。

Most copper cleaned with cyanide will have a rosy hue for a day or so after cleaning but on exposure to air will return to a nice copper color, so it is well to wait a day or two before lacquering the copper.
