Does anyone know the chemical composition and mechanical properties of Rd65 VL22 Copper alloy. Or where I could get it from. Also the Standard from which this material comes from would be useful.
I have searched the internet and am unable to find its specification.
Thanks,
Martin

Dear CWatters:
Copper and zinc make brass. You did a lot better than I did. I could find no listing of anything useful on google with the information supplied. Good work!

I guessed that the Rd65 part might refer to the percentage of Copper (or something like that) and deleted it from the search. eg
You are possibly mistaken in thinking this designates a copper/brass/bronze alloy.
Accordingly, you could go with an engineering approach: what material would I like for a worm? A phosphor bronze, likely
Brian Whatcott Altus OK
I thought 9 copper : 1 tin was brass. And that 1 copper : 9 tin was bronze. I thought some math textbook from when I was a kid said this. Maybe 9 copper : 1 tin for BRONZE would be okay, judging by a few internet pages. Is there some other thing which is 10% copper, 90% tin? I saw some mention of pewter with this kind of ratio. To the OP's question, I didn't even know that worms had gears.

Dear operator jay:
No. Copper-zinc alloy is brass, in "any" proportion. Don't use brass in vacuum, as zinc has a vapor pressure. Copper-tin alloy is bronze.
Mechanical ones do!

I dont think that "Rd65 VL22 Copper alloy" is an ASTM designation. This could be a trade name or part number. Not sure.
I would try to find some worm gear manufacturers online and see which alloys they use. I'm betting it's ChromeVanadium Steel.
If it's a copper alloy, it might be an Aluminum Bronze, which is frequently used for gears.
2) Are you sure about the R "d" 65? If it is actually a "b", that would be the hardness used in bronze gears. The D scale is a lot harder than the C used for steel or the B used for bronze. The D would show up if the bronze was somehow face-hardened.
3) I think, but I wouldn't bet the house, that it is from a French or German mfg4) If you had a CDA (Copper development Association) number for the alloy, the alloy that was registered by the manufacturer to get a number, it would help a lot.

supplied.
Brass is a Cu--Zn alloy
Bronze is a Cu--Sn alloy.
The only reference on the web I could is this company....
