Comp Ti Retainers

Lynn · 10-21-04, 03:39 PM

Has anyone ever actually held a Comp Cams titanium retainer in their hands? Are there any kind of identifying marks on them?

Thanks,
Lynn

Yes - and as far as I recall - No.

If I recall correctly, titanium is non-mangetic.

Brian,

Since I didn't get to be until around 2AM, I guess I am pretty dense this morning; and your point is what?

Regards,
Lynn

Paul,

I went to the Comp website and found some pretty detailed photos and they did not reveal any markings at all.

Thank you,
Lynn

If a magnet doesn't stick to them, they're not ordinary steel (unless they're a variety of stainless), so they could be titanium.

My thoughts precisely, thanks Ben.

I really was dense this morning, it was about midday when I suddenly realized what you were saying. In the meantime, some guys on another forum gave me a great way to check them:

Metals have specific densities
Ti = 4.54 g/ml (for the most common Ti alloys)
Al = 2.7 g/mL,
steel= 7.85 g/mL

So, I can find out how many mL of metal I have by seeing how much water they displace when I submerge them. Then I can weigh them and calculate their density. I should them be able to get a warm fuzzy as to what they are. There is enough difference in the given values that I don't even have to be super accurate to get in the ball park. Of course this won't tell me if they are good US Ti or if they are from Russia or China.

I have asked the guy straight out if they are Comp retainers or not and if they are not, if he knows where they come from. We'll see how it turns out.

Thanks,
Lynn

Makes sense that there are no markings on them, as I understand titanum is very notch sensitive.

I am assuming you are correct, I am not sure one way or the other, but be that as it may, here is one of example of Ti retainers that have been marked:

When I click on it, it tells me that I have to be logged in to the corner carvers forum to see the immage.
