Need help finding a material...

[jinu117]

Basically I am looking for a material (some sort of metal I would presume) that has high tensile strength, doesn't melt at the temperature of brazing, and can be machined.
Quick search arounds for me netted, carbon (not sure if it can hold 20lbs of force ehehe), Tungsten (probably would work... but how the hell do you machine these?)
I am pretty sure there are some out there than can endure higher temperature... while being able to hold the kind of pressure under temperature)...
I would really appreciate help on this
TIA.

What working pressure are you aiming for?

Don't know exactly what you need it for but what about good old 1018 cold rolled steel? It will take brazing easily and being a dis-similar metal it will be easier to remove the "slag" from brazing. also it machines very easily and is dirt cheap.

4140

Stainless steel?

I've 18 titanium pins that came out of me 3 weeks ago. I guess if you smelted them you'd get something out?

Harmonic is really heavy duty, not much kills it but it's heavy! Oh and it's steel

Like Gosmeyer said, 4130 is great. Use to use it a lot to build bike frames, aka cromoly

Ooo thinking about. T45, steel again, good weight but 45 tons of presure and stuff! Nice to work with when brazing or tig'ing

I don't know much about metals but the first thing that comes to mind is titanium. It is very strong, machinable and very light if that matters to you. It is very expensive though.

I don't get what you're trying to do Jin, and why copper or brass won't work? Brass is very strong, tensile strength is about the same as a low carbon steel. Either copper or brass can withstand enormous internal pressures with the proper wall thickness. 1/8 annnealed copper tubing is rated for 3000+ psig at 100F.

Thanks Detroit Actually that is the conclusion I came up with today morning ahaha. Basically, I am thinking about a process of making something and need pressure for it. Didn't want the contracept to melt away from brazing heat over time, etc... Than it came to me, as long as it transfers heat at about same rate... why the hell would it melt... (unless... the brazed material is melting).

What are you trying to do... build a bomb and you want to make sure the shards wont vaporize?

Seriously though, I'm quite confused as to what you want to even do...

[stuntingalone]

ditto lol *BOOM*

[Polizei]

Titanium maybe? Titanium alloy perhaps?

[ruffus]

well the only thing that would do anything you want it to do it is tungsten or tungstencarbide but the are expensive and i don't know if you can braze it but it is the strongest metal out there that i know off and if you could not braze it you could get it copper plated then you could braze it
