SRC Member DUCADOS Posted May 20, 2010 SRC Member Share Posted May 20, 2010 Wat do u mean by loose sell? U need straight tube n bent it yourself ah? That's y their ready made coil u dun wan izzit? Titanium r tough metal(hard to shape) that's y alot people dun have such material. Most of time will required ordering. My dad is in oil rig field n precision engineering. Let me know the size c I can help. Quote Some1 doesn't 1 2 do anything find an excuse,some1 1 2 do something find a mean! Link to comment Share on other sites More sharing options...

Let me know the size c I can help. I tot titanium alloy can be bent easily depends the alloys contain...... If not confident, we can apply heat when bending... pure titanium is even much softer and elastic... but a bit X.... Pls verify ya... Thanks Cheers and Happy reefing..

SRC Member DUCADOS Posted May 20, 2010 SRC Member Share Posted May 20, 2010 I think you mistaken it with aluminium. Titanium are tough metal. Tough metal for titanium is a yes n no coz it falls in between the toughest n the weakest n for weight it also falls in between lightest n heaviest. That's y it's classified as the lightest strongest metal. Compared to aluminium,titanium is tougher but slight heavier. Compared to steel,it's not as tough but lighter.

SRC Member DUCADOS Posted May 20, 2010 SRC Member Share Posted May 20, 2010 The ultimate reason for people to use titanium is that they can withstand drastic change of temp without crack or break. Sudden drop or rise in temp for this so call ''devil metal'' in the metal industries is well know for it's way of flexibility.

SRC Member DUCADOS Posted May 20, 2010 SRC Member Share Posted May 20, 2010 Not susprise with bro mitlancer quote coz I use to think of self milling a pc of RC car undercarriage using titanium coz they sell ready made wan quite ex. End day ask dad to ask coz my dad got no balance material left. Was quoted like $600 for a pc of 1 n half feet by 1 feet titanium sheet. Drop the idea at the end. Sian 1/2 lol Quote Some1 doesn't 1 2 do anything find an excuse,some1 1 2 do something find a mean! Link to comment Share on other sites More sharing options...
CFOh Posted May 20, 2010 Share Posted May 20, 2010 I think you mistaken it with aluminium. Titanium are tough metal. Thanks BFG.... Just notice the feedback... Sorry, I didn't address properly what I mean.... I think DUCADOS catch some point..... cause colleage time we r using "Fe" metal base for metal sheet works (it is cheap).... Therefore, I believe it can be fold even easier than normal metal sheet... As compare to "Fe", "Ti" much lower in term of Rockwell performance and also Young's modulus characteritic. and it is slightly harder than "Al" but still far softer than "Fe" in term of numbers..This is why I say "Soft"...

Let me know the size c I can help. Until now I still did not get it. As for ready made coil is quite big like for 1 HP compressor. the size thai I need is very small Daimeter ~6mm and coil just 4-5 level with diameter of around 10 cm. My idea is to use peltier attched to coil then run water through to chill it.

SRC Member DUCADOS Posted May 21, 2010 SRC Member Share Posted May 21, 2010 Wat I meant was titanium is a kind of metal that is hard to deal with. Must be confusing?Since I mention softer than steel then y izzit hard to deal with? Coz during shaping,regardless milling,lathe,drill or cut,this metal tends to stick on cutting tools n hence make shaping difficult. E.g people can cut many pcs of steel using 1 cutting tool. For titanium maybe 1pc to 1 tool. Then cutting tools either wear or blunt. That's y if u were to ask them do something using titanium,their immediate reaction will be asking possible to use other material? If only when u insist then they either turn u down or mean they will charge u sky high price for labour cost. Quote Some1 doesn't 1 2 do anything find an excuse,some1 1 2 do something find a mean!

SRC Member DUCADOS Posted May 21, 2010 SRC Member Share Posted May 21, 2010 Copper not possible? Will crack izzit? Very good conductivity of temperature n most important cheaper than titanium in terms of price n manufacturing. Good luck dude!

Very good conductivity of temperature n most important cheaper than titanium in terms of price n manufacturing. Good luck dude! yes, copper has a much better thermal conductivity than titanium. In fact titanium is not a good thermal conductor. It is used in marine because it has better corrode resistance property than the rest of the metal. Copper, ppl fear corrode and will create Cu oxide will leak into main tank and corals cannot withstand high copper. Alternative is to use aluminum, thermal conductivity is in between the 2 and so far I do not see any articles saying aluminum may affect corals.... Just to share what I know.... correct me if wrong.

SRC Member DUCADOS Posted May 21, 2010 SRC Member Share Posted May 21, 2010 If I not wrong yes aluminium do affect the water n coral. If u notice marine tank doesn't comes with aluminium frame. This is part is the reason. Quote Some1 doesn't 1 2 do anything find an excuse,some1 1 2 do something find a mean! Link to comment Share on other sites More sharing options...

My idea is to use peltier attched to coil then run water through to chill it. You may want to reconsider your design. How are you going to attach the titanium coil to the flat peltier? Peltier itself is not energy efficient + the low thermal transfer junction between the 2. I seriously doubt that there will be any significant cooling effect. Titanium is not easy to work with, they are quite elastic and not easy to bend. Once you try, you will know. Quote Link to comment Share on other sites More sharing options...

Hi, Just share something from my bookshelf... "Introduction to Engineering Material pg 423-425" by Vernon John about Corrosion, Electrode potential (Anodic V Cathodic) and galvanic series in sea water... In summary: for some guideline, do not used material towards anodic (pg 423)... another words whichever, material shows Electrode potential < 1V, anodic material tends exhibited more prone to oxidation... or rust/corroded in layman term.... That is the reason Aluminium, Copper both are not advisable.... the galvanic series in sea water (pg 424).... Titanium shows the best 2nd after gold in cathodic category... Therefore, in general.. titanium corrosion resistance is higher than others.. but they have their own weakness..which doesn't effect us much .. That is also some other terminology... probably we can discuss later.... Hopes above few lines helps explain some of your doubt.... Cheers and Happy Reefing...
