We always used minimum 45% silver solder for braise-welding copper pipe to stainless steel. The flux was a liqid-paste containing borax and flouride compounds. As I recall the brazing temp was about 600 deg. C. The application was to pipe oxgen gas at 2,000psi.

Machining PTFE is a black art and those that know rarely divulge their hard won knowlege for free. We sometimes make seals from PTFE but generally avoid using the stuff. It has a low modulus, low resilience, practically no compressive nor tensile strength and because it has high thermal...
nornrich in addition to the information supplied by unclesyd. I strongly suggest you look at the Kolsterising process or one of its clones. Choose 316L or a duplex type stainless, but preferably a ss with plenty of chrome, and Mo. The process allows carbon to form carbide compounds with Fe and...

My project is a rectangular box of sorts that will be injection molded and I need to know what polymer will give me the equivalent properties of 1mm of steel or aluminum.
I know that in most cases a "thicker" polymer is used to make up for the loss of strength. This is not an option for me.

When you send your resume in, assume at least three people will expect a copy. Send in three clearly separated, but original copies. That way you may just have the little edge needed.
"........Although the ball diameter is much smaller than the ring radius, its contribution to thermal problems could be also signaficant due to higher temperature. This way I explain to myself the superiority of oil-air lube in high-speed applications."

Part cured phenolic resin dissolves into most alcohols and acetone is one of the more agressive solvents.
We use acetone only for cleaning solvent.
To test a phenolic part for cure, we rely on a special hot compression test developed in-house. Properly cured and partially cured phenolic resin...
I would also like to say that while acetone may be useful for extracting unreactants, over time and above acetone also attacks perfectly cured phenolic. IMO it is a destructive test therefore the test part should be isolated from and not returned to the batch.

Another take on TheTick's superb quote: "Decision is clean cut, easily mended, blended, repaired or removed. Indecision is ragged edged with loose threads and jams everything associated with it.
As long as carbon fibers are prevented from being in electrical contact with the metal part it should be OK. Longer term chafing might be worth considering.
It will be a "battery" only if it gets wet. Even if you use ss, if does get wet, it won't help if salt is present and can accumulate. Isolate the two materials with a creep resisting electrical insulator such as epoxy grp, heavy film Mylar from Dupont. Electrical insulation specialist suppliers...
