*请注意：如果您有兴趣使用Muntz Metal，请致电讨论项目详细信息。虽然我们不会在手头上保留这种材料的样本，但我们很乐意根据项目的需求来定制.Muntz金属是一种主要使用铜（60％），锌（40％）和铁痕迹制造的铜合金。作为铜锌合金，它落在黄油下，并由寻求合金的设计师使用，该合金为室内设计灰色黄色色调。Muntz Metal从Inventor获得的名字乔治F. Muntz在1832年开发了船船体衬里的合金.Muntz Metal最适合室内应用和更少的低压力外部应用。这种合金是最高的黄铜合金，并且处于β相的极端。出于这个原因，它的应力下的行为与韧性黄铜黄铜和盒式黄铜的影响。它也存在脱锌腐蚀的风险，其中小暗坑出现在失效的金属表面中。压力骨折腐蚀是另一个必须考虑的担忧。可以努力工作这种材料是可能的，但困难。α/β黄铜的缺点，是合金在严重的冷加工操作下会破裂。间隙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.
