Copper anti-seize question
After the recent titanium thread I have a question on copper
anti-seize grease. Does it cause galvanic corrosion to aluminum or other metals? Copper is way below aluminum in potential. Don't know about titanium. Thanks |

Don't know about titanium. Although I have not used the copper version often, in the instances where I have employed it and then had occasion to disassemble the item after a significant period in service, I found no evidence that the copper or the metals in contact with it were corroded at of near the points of contact. Beyond that margin, it would be hard to establish whether the copper was involved in any corrosion. The grey/silver versions of anti-sieze formulas generally have powdered aluminum in them, though there is at least one which uses powdered nickel instead. I have used the powdered nickel version in the past, and found it to have no advantage over the cheaper aluminum compound. I have also seem some mechanics employ such anti-sieze compounds in engine assembly as a coating on the faces of cam lobes and lifters; knowing what's in them, I would caution against this application. I would additionally caution against using any anti-sieze preparation containing metal particles as a bearing grease or grease additive, for obvious reasons. -- Typoes are a feature, not a bug.

Dear Werehatrack, Why can't students remember simple spelling rules? I before E except after C (receive and deceive, but not fallacies, vacancies, science, species, or society) . . . . . . and in words like neighbor, weigh, weight, freight, weird, sleigh, sleight, height, being, seeing, boeing, feisty, gneiss, heifer, schneider, deign, eisenhower, protein, seine, eight, heist, rein, einstein, either, surfeit, frankenstein, codeine, sovereign, heir, alzheimer, seismic, neither, stein, lei, deity, foreign, sheila, vein, obeisance, keister, sheik, feint, and a few other pesky exceptions, such as seize. In the days before spell-checkers, I wrote a master's thesis that wasted time on the subject of embarassment in the works of Mark Twain. An embarassing spelling mistake was pointed out on a few dozen pages of my first draft. Luckily, my advisor was kindly enough to mention the missing -r- only once in our conversations. "It is a damn poor mind that can think of only one way to spell a word." -- Andrew Jackson Cheirrs, Carl Fogel |

Beyond that margin, it would be hard to establish whether the copper was involved in any corrosion. To the list: TiPrep is a copper-compound anti seize lube. Profile ships a tiny smpler of it with their Ti BB set. I've used it (cro-moly crank arms to Ti spindle for several years and have had no problem with corrosion or seizure. I bought an 8 oz can of the stuff from J&B and I use it on everything now. later jn "Thursday" |
