COPPER ALLOY CLEANING PROCESS |
摘要 |
A process for removing surface oxides from copper alloys. For example, those alloys which form, on annealing, A12O3 and related oxides are uniquely cleaned by a process which consists of a duplex treatment requiring a first immersion in a hot alkaline solution followed by a second immersion in a hot mineral acid solution.
