Todays question has to do with epoxy glues. For years I have used SystemIII T88 epoxy as my go to epoxy for everything including segmenting acrylics to metals and wood. I have used JB-Weld 8280 epoxy for metal to metal mostly.

My question is I want to do some segmenting work using brass to brass, aluminum to aluminum and combination of both. The ideas I have will have a high pucker factor when being turned. Not worried about drilling. 

Is there a stronger epoxy weather a one part or a two part stronger than JB-Weld and if so what is it and where to get it???. Have you had hands on experience with it??? Can it be tinted black if it does not come black??? With todays advancements in every area I just thought I would throw it out here. I know from watching this site that there are not many segmenters and not many that use metals but maybe in the auto industry or aviation industry there maybe a product worthy of a try. Thanks for the feedback.

If I use epoxy in in my business, it's because the right way didn't work. I've been known to reattach bumpers to the car with 5 minute JB Weld. It doesn't set near as hard as the reguar B Weld... that being said.

Back in the day, I worked at Stanford (SLAC) and we used DEVCON products for everything. We built electromagnets (some the size of a bus) and used Devcon to hold the conductors in place. Some of these conductors were as big around as the business end of a baseball bat. Some were copper, some were aluminum. The stuff stuck to it. It was also machinable. I'd Google Devcon Adhesives and see if there's something available retail that might work.

My recollection is that Devcon and JB Weld are the same company.  That being said, Devcon has a number of products that are better than JB Weld. Particularly with different filler metals. I am not sure for your application.  They are metal filled epoxy.  I assume you can get application notes for Devcon products, I would look through them.

I first heard about Devcon when I was involved in fixing battle damaged airplanes.  The technicians filled a fairly deep dent in one of the control surfaces.  It was great for that, really strong.  I'm not sure about the strength of a thin glue line between two pieces of metal.
