Simple question, titanium? I know fighter airplanes are made from it, I even have a road bike, the frame is made out of it. Razors? Anybody knows, I am no metallurgist, hec I don't even know how to spell it. Do they make razors out of this metal? Juan.
Titanium is strong, lightweight, and durable but it can not be heat hardened and is only about a 45 on the Rockwell C scale. It is too soft for any type of blade but makes good handles.
What are you doing up at this hour, you and I should be in bed by this time. Juan.
Anything at all to make a buck, does not mean that Enigizer corp's Shick Quatro Titanium and Enigizer Shick Quatro Titanium Trimmer have any of the stuff in it, personally I think its all plastic.
Eh? MissionKnives.com, The Toughest Knives in the World! and root around a little.Quote:

A very tough knife, but true, probably not a very good razor.
The titanium coatings used on cutting tools is a deposition layer of titanium nitride or carbide, sometimes even boron. Rc 80, very hard stuff, not just plastics.
I guess when you see Titanium in all those pretty colors that's the result of heat treatment.
Color oxides will form with heating, but for the most part, those colors are formed as a result of an electrolyte bath (even coca cola) and electric current. The colors result from varying the voltage and the equipment is really kind of easy to build at home.Quote:

And then to run this subject out into the fringes, Tom Ferry, Oregon/WA, has made a pattern welded titanium material (timascus). That gets really interesting since the welding temperatures are critical and it has to be done in the absence of oxygen. Think of a magnesium fire on steroids. :)
very interesting mr. blue
thanks for posting
So we have to find a titanium nitride razor - right? I had no idea that the Rockwell C scale was different for titanium than it is for steel. A rockwell 61c is different for steel than it is for other metals? I guess they should have called it the Rockwell C metal dependant sliding scale.Quote:

And that's for a KNIFE.
Just imagine for a razor.
As for Quattro Titanium, it's probably more of a titanium coating.
I think it is just a coating. If i remember right they even mention in the commercials that the blade is "titanium coated". I could be wrong though. I thought i was wrong one time, but i was mistaken :rolleyes:.
Perhaps I led you to a different conclusion. The Rockwell scales (also Brinel Vickers etc.) are standardized methods of determining hardness. Rockwell C scale at 45 on a titanium blade would be Rc 45 on a steel blade. The Rockwell test is not the problem.Quote:

As a very thin coating over disposable materials, like razors or drill bits, it works very well. But eventually, even when backed up by a steel edge, the normal wear and tear will require honing and then the titanium coatings, despite being tough, will abrade away, leaving exposed steel again.
The titanium knives have the advantage of being non magnetic. Good for EOD divers working around mines with magnetic triggers. I would agree that they are not the ultimate in performance edges.
