芒茨
*请注意：如果你有兴趣与芒茨金属加工，欢迎来电洽谈项目的详细信息。虽然我们不保持手头这种材料的样本，我们很高兴来定制基于项目的needs.Muntz金属主要使用铜（60％），锌（40％），和铁的痕迹由铜合金制成。作为铜 - 锌合金，它落在黄铜下，并且被用于由设计者寻求表现出对内部灰色黄色调的合金。芒茨金属从它的发明者，乔治·芒茨，谁开发了船体在1832.Muntz金属衬里的合金是最适合用于室内应用和较少的低应力外部应用获取了它的名字。这种合金的最高编号的黄铜合金和处于β相的最末端。出于这个原因，它的压力之下发散行为与韧黄铜管和铜墨盒的。也正是在脱锌腐蚀，其中小暗坑出现在失败的金属表面上的风险。应力性骨折腐蚀是另一种担心，必须considered.Cold加工这种材料是可能的，但困难。α/β黄铜的缺点是，该合金将在严重冷加工操作开裂。间质性退火需要形成严重的形状。 The annealing generates oxides on the surface, which are difficult to remove. Under hot-forming operations this alloy performs well. Hot-forming processes are not commonly used for shaping architectural metal features. Hot forming will build up oxides on the surface, and discoloration of the surface will require post-polishing. However, welding and brazing this alloy is not an easy task and should be done with care.Using lower cold-rolled tempers does little to soften this hard alloy. Muntz metal can be polished to a mirror finish. Satin polishes and custom polishing are also possible with this striking architectural alloy. It will take statuary finishes in all the available ranges. When used on the exterior of a building, Muntz metal should be protected with a clear coating. There are only a few available cold-working tempers.Maintaining the color on Muntz metal requires either periodic polishing or sealing the material. The bright reflective brass color of Muntz metal will fade, losing reflectivity, and develop over time into a gray-green patina.
