I was wondering if titanium will rust? Or how rust proof it is? I was also wondering how strong it is compared to steel or aluminum?
 
No rust. Strength to weight much higher than alum or steel. But it scratches.
 
titanium does not rust. it is EXTREMELY strong much strong than aluminum or steel. This does not mean it is harder than steel. It has a higher tensile strength. This is why it is uncommon to see it used in a blade as it can only be hardened to 50 rockwell. it is often used in spacdecraft due to its extemely high strength and low weight.

There are some chemicals that can cause titanium to corrode, but usually only at high temperatures. High strength titanium alloys have yield strengths similar to carbon steels, but cheaper grades have much lower strength.
 
For the cost and compromise in using Ti knives, you may as well use good stainless or regular high carbon knives and just take care of it.
 
Or if you need a knife that won't rust get something using H1 steel, like the Salt series from Spyderco.
 
I don't think he was talking about using it for a knife blade i think he was just asking general questions about titanium.

Noob here. I was wondering if a magnet will attach to titanium?

No there are only three magnetic elements(At room temperature), Iron, Nickel and Cobalt. All other metals require special circumstances to be metallic.

To answer the previous question, a sample of titanium, say a sheet about two inches thick, is about as strong, in tensile strength, as a sheet of steel, two or three times that, while having the weight a little bit heavier than a sheet of aluminum of the same size.
However, as said above, it is not very hard so it scratches and it does not hold an edge very well and is therefore not very useful for blades it does make good strong handles if you don't mind the accumulation of scratches.
 
Titanium is not necessarily stronger than steel. "Strength" can also be defined differently (tensile, compression, etc). If strength is your only concern, you can find alloys of steel, with proper heat treatment, that are as strong as or stronger than titanium.

Where titanium excels is in its strength-to-weight ratio. You can either use the same weight of titanium as steel and have it be stronger, or (far more commonly), use the same volume of titanium, have the same strength as steel, but with far less weight.
 
Mission makes a first class Beta Titanium knife. I have one and always will. Check out their website.
 
I had Reese Weiland make a Ti blade for my Emerson scales that were left over after a framelock conversion. It holds an edge ok (approx AUS6), but wouldn't be my first choice. I had it made mainly for novelty purposes but I didn't want to let the Emerson guts go to waste.

I own a Mission Ti folder that is a great knife but only comes out when I go swimming. I have a Ti fixed blade fighter from Reese that's almost ready to be shipped. That is mainly an art piece, with a torch colored temper line and a rayskin asian styled wrapped handle.

Tell me more about these metals that are only metallic under special circumstances :confused:

:D:thumbup:
