Donnie Posted July 25, 2014 Share Posted July 25, 2014 Is there any reason not to use copper rivets to join steel? Quote Link to comment Share on other sites More sharing options...
njanvilman Posted July 25, 2014 Share Posted July 25, 2014 I have used copper rivets for work that stays indoors. Copper rivets are a bit softer than iron or steel rivets, but if the design is correct, they should work just as well. No issues after many years. I will defer to others as to whether they will work on outdoor ironwork, exposed to rain, etc. I have never tried that. Quote Link to comment Share on other sites More sharing options...
John McPherson Posted July 25, 2014 Share Posted July 25, 2014 You mean other than being half the strength, 10 times the cost, and causing galvanic corrosion if they get wet? Why, no, not that I can think of. On the other hand they do tend to make nice accents on decorative pieces, and that means you can charge more!

Donnie Posted July 25, 2014 Author Share Posted July 25, 2014 It will be an indoor wall hanger. I wanted to use 1/8" rivets. I have some copper ones that size. I've never joined steel with copper. I didn't know if there would be any type of reactivity over time. Thanks for your reply. Quote Link to comment Share on other sites More sharing options...
the iron dwarf Posted July 25, 2014 Share Posted July 25, 2014 if dry it would be ok, if damp not so good Quote Link to comment Share on other sites More sharing options...
ianinsa Posted July 26, 2014 Share Posted July 26, 2014 Donnie, You know that you're joining dissimilar metals that will 'attack ' each other but if you keep it dry and indoors you will just have to accept that the lifespan may be limited to 100 - 200 years give or take 20 years.(grin) Quote Link to comment Share on other sites More sharing options...
Donnie Posted July 26, 2014 Author Share Posted July 26, 2014 Hmmmm, 100-200 yrs. That would be long enough for me. But, the way my luck goes, someone would dig me up to complain about it. I think I will just make a handful of steel rivets. Quote Link to comment Share on other sites More sharing options...
VaughnT Posted August 3, 2014 Share Posted August 3, 2014 Regular ol' nails make great rivets and you can get them in a variety of sizes. There was a video around here somewhere that showed some Haitian (?) guys using them to fab cooking stands. Can't get much cheaper than a box of nails, and then you only have to cut them to length and peen the one end. Copper and brass work plenty well. The reaction between the two metals is super slow and certainly nothing I'd worry about. Even in an humid environment, you're probably looking at 50 years of solid service.

EtownAndrew Posted August 3, 2014 Share Posted August 3, 2014 I have used copper rivets to put together knives and I like them. They peen easy and look nice. So far they have held up fine. I use various wire sizes depending upon how big a rivet I want. Quote Link to comment Share on other sites More sharing options...
arftist Posted August 5, 2014 Share Posted August 5, 2014 Clinker built boats have been built with copper rivets for centuries. As to metalworking, I like the distinct contrast. Quote Link to comment Share on other sites More sharing options...
Nobody Special Posted August 5, 2014 Share Posted August 5, 2014 Well, generally speaking, wouldn't you coat your outdoor work with something to keep it dry and protected anyways? I don't have rivets, but I've made windchimes with laquered copper wire and scales, frame was from 3/8"-ish mild steel. Coated the wire before, and sprayed everything down with clearcoat after. Only been 4-5 months outside on the one I kept, but no corrosion.......so far. Quote Link to comment Share on other sites More sharing options...
the iron dwarf Posted August 5, 2014 Share Posted August 5, 2014 sometimes a little corrosion can add a nice aged look Quote Link to comment Share on other sites More sharing options...
Hardpan Posted August 6, 2014 Share Posted August 6, 2014 I've been pondering using copper rivets in a hanging pot rack ~ the contrast is an appealing thought. As far as dry... hmm... wonder how many decades it'd take the steam from cooking to cause the galvanic self-destruction... :rolleyes: Quote Link to comment Share on other sites More sharing options...
anvil Posted August 7, 2014 Share Posted August 7, 2014 I did an outside weather vane that had copper stripes on mild steel. It was a wasp. I put a light coat of silicone between the copper and mild steel. That was 20 some years ago. There's been no problem. Quote Link to comment Share on other sites More sharing options...
