Titanium was not listed on this chart but the Kitplanes article I got this from said that it is down near the bottom. Like materials in contact will corrode less. You can also insulate active materials from each other with fiberglass or paint if you can keep the joint dry. Here is the chart in order of potential: Anodic (most active) Magnesium alloys Zinc Alclad 7000 series aluminum alloy bare 5000 series aluminum alloy bare 7000 series aluminum alloy cadmium bare 2000 series aluminum alloy steel/iron lead chromium brass/bronze alloys copper stainless steel/high heat steels silver nickel/high nickel alloys graphite composites cathodic (least active) (from Sept 97 Kitplanes, pg. 34) >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> LML website: http://www.olsusa.com/Users/Mkaye/maillist.html LML Builders' Bookstore: http://www.buildersbooks.com/lancair Please send your photos and drawings to marvkaye@olsusa.com. >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
