We are required to plate a large number of aluminum parts. Are there any other ways to prepare the aluminum for plating that do not involve the zincating process? K. J.
Yes, there are alternatives to the classic zincating process used for preparing aluminum for plating. Two such processes are as follows:
The second process is an anodizing process:
As can be seen both of these processes are not necessarily any less complicated than the zincating process and hence are not seen that often in plating operations. In addition, the first process uses proprietary materials that may or may not still be available.
The bottom line on this is that unless your customer requires a process without zinc, stay with the zincating process.
