黄铜和铜合金

这是它都开始用于MacDermid的地方。乐动app苹果1922年,Mac乐动app苹果dermids的创始人Archie Macdermid开发了我们现在的第一个黄铜的世界级清洁剂。他和公司成立了申请知识的声誉,即使今天是在客户哲学的核心。

Anodex NP-2,原始的MacDermid E乐动app苹果nthone黄铜清洁剂仍然是我们顶级产品之一,以及专门为清洁黄铜和铜合金而产生的产品,影响即使是最高抛光的表面也是如此。

预处理和最终饰面

铝offers engineers a lightweight, electrically conductive material which is easy to machine and mold. It is often electroplated to improve the appearance and improve corrosion protection. Applications for plated aluminum include:

  • Chromium plated aluminum (alloy) wheels
  • Connectors for aerospace and military finished with either electroless nickel or zinc-nickel alloy
  • Extrusion for construction finished with decorative coatings such as satin or dark chromium

基于锌的压铸铜和镀镍

  1. Pre-clean in polishing compound remover Metex* SU 486
  2. Soak clean in Metex S 1702
  3. Anodic clean in Metex EN 1751
  4. Acid dip in Metex M-629 Dry Acid Salt
  5. Alkaline copper strike**
  6. Alkaline copper plate in Cuprobrite 3
  7. Clepo SP中的焦磷酸铜板
  8. Bright acid copper plate in CuMac Optima
  9. Nickel plate from the Elpelyt range


* Other cleaning systems may be recommended for the complete process sequence depending on component and soiling type. These are only given as a guideline.

** Where zinc base diecastings are plated in large numbers it is advisable that, even before alkaline copper plating, the diecastings be initially flash coppered in a copper ‘strike.’ The use of a copper ‘strike’ reduces the possibility of zinc contamination of the main copper solution. Where an acid or pyrophosphate copper solution is employed, a preliminary cyanide copper flash is essential.
