The lifetime of the anodization handle of a ball lock pin is 336 hours in salt spray test.
this is only valid for parts that are not graved with their part number on the handle.

the anodization is something you need to request and can be typically red, blue, yellow or other color.

The anodization is performed according to MIL-A-8625 standard

if you want to know the performance when the parts are supplied not blank but with a lasered part number on the handle, then we can do a test to measure the result, but we will have to quote this

the consistency in color across different batches is achieved by using the same dye trademark for each batch

color codes of anodization :to be added at the end of the part number
