Re: Tailbrace Wire Questions
On certificated turbine engines we ROUTINELY mix and match Aluminum, steel, and stainless fittings (among a multitude of other exotic metals). This is done by the engine manufacturer, at the production facility, on every engine that goes out the door.
Any possibility corrosion is eliminated by completely assembling the parts with WET zinc chromate. The trick is to have everything assembled, torqued, and in place before it dries.
If it’s good enough for a 330PSI, 200*C bleed air system on an engine operating at 33,000 RPM, at 41,000'; It’s good enough for my Taylorcraft flying wires operating 100MPH at 1,500'.
Use a Q-tip and WET zinc chromate on as you assemble the wires, nipples, nuts, and straps. Put it right on all the threads. You will not have any corrosion problems.
