Titanium Blade?
I recieved some titanium the other day. They were some drop
pieces, 1/8" thick by 1" wide by 12" long, as well as a few thinner pieces and even more on the way. It is labeled as grade 2 titanium. Will this in any way make a decent knife blade? Thanks for any replies, Jeff |

From what ive heard titanium doesnt make a good blade material but is commonly used as fittings and sides on folders. Its a really tough metal but from what I heard its not a good blade material... Notice im using the words from what I heard.

Short version
Grade 1 and grade 2 is unalloyed titanium and by that too soft for knives. For knifeblades only alloyed titanium is hard enough (and in comparison to steel still quite soft). Long version I have no HRC-values for unalloyed titanium, but for titanium-alloys: "beta titanium" has between 44 and 46 HRC, TiAl6V4 (used eg. for framelock-frames) has about 38 HRC 2 examples for beta-titanium: 1. Beta III (UNS R 58030) Ti-11,5Mo-6Zr-4,5Sn ~ 40 HRC 2. Titan Beta 21S (UNS R 58210) Ti-3Al-0,3Fe-15Mo-28Nb-0,2Si ~ 43,6 HRC If 0.25% Oxigene is added than you get about 46 HRC. The advantage of titanium is that it doesn't rust, but it's hard to machine & beta titanium is quite expensive. I would only use it for a divers' knife. Hope that helps. |

I have a number of titanium blades with press-fit stellite edges.
Another alternative is to coat the edge. Warren Thomas did a bunch of these: Warren Thomas Carbide edged Titanium knives at BladeArt There are a lot of titanium dive knives being made: http://scuba.about.com/cs/equiprevie...niumknives.htm Ocean Master has a titanium formulation they claim HRC of 51-54. Ocean Master Material Properties There are also a variety of titanium concoctions being tried, for example Boker has both Titanium-carbide and sintered Titanium/Ceramic/Silver blades.

Thank you for all of the replies. I will probably make a few knives just as conversation pieces or oversized letter openers. They would probably make neat butter knives for dinner.
Thanks again for all of the replies Jeff |

That would be the sweetest butter knife ever, maybe you could make a few and some forks and a Ti pie server to go with it and have a desert set.

Hello Charles. I'll suggest checking the dates before responding to threads. The OP's question was almost 15 years ago, and the most recent post was about 5 years ago, so I'm not sure the folks with the questions need an answer anymore.
