Alodine 1200 S and MY-14

Tiistai 20.2.2018 - Reino Myllymäki


There were several different process in order to enhance the corrosion protection of aluminium alloys in the 1940s. For example, the bulkheads may got either VLO 32742 part 40 and 41 processes (anodic treatment and bichromating) or part 42 process (treating in chromium nitric acid).


That kind of processes or agents were not in use anymore. MY-14's bulkheads are reproduced from new material by using design drawings and survived parts of bulkheads. Now they were yellow chromated by Alodine 1200 S process. Same process was used for the bottom access panel and instrument panels.


Alodine 1200 S process for MY-14's parts was provided by Patricomp Oy.
