Silver and Titanium Ratio

[bradaz2722]

Hello I'm making my wedding rings and I've got more then enough heirloom silver to make my 6mm Q and a 4mm O 1/2 for my wife-to-be. But I would like to add some titanium for its strength and resistance to the elements. What ratio would be advised for an Ag:Ti alloy?

Ti + 4.5% Ag you wont melt it with propane /LPG

Sentimental value or not, you ill be creating an alloy that can't be hallmarked so rendering it a 'white metal' of unpredictable hue.

Why not sell it and buy 9 ct oval white wire instead, which will give you beautiful hard wearing white rings with a slight yellow cast. Dennis.

Inert atmosphere, TIG torch & graphite crucible. Pretty much the only small-scale way to alloy that mix.

http://www.dtic.mil/dtic/tr/fulltext/u2/018321.pdf also has some detail on an Ti/Ag binary alloy; there are papers out there on Ag/Ti/Cu & Ti/Ag/Pd ternary alloys. At the very least you'd need to locate appropriate phase diagrams - and there seems to be an issue with intermetallics between Ti & Ag.

Dennis.Appearances in hue and cash value are insignificant, it's more the fact I'm creating them from her recently passed father's rings. I've bought way to much equipment such as crucibles and torches and had spent plenty of time researching how to sand cast, I got my heart on making them this way. Unfortunately my science isn't great and in particular elements and alloy stability.
I thought mixing silver and titanium would give them better strength and from what I've found out less likely to tarnish. I was going to just cast the silver and have them rhodium plated but soon drifted away from that idea as they will need replating as time goes on. I was hoping for a 50/50 mix of the two but I've got a year to get to the bottom of this.
If you are interested in the outcome I will return here with the finished rings.
Thank you for your reply

Yes, we will certainly look forward to seeing the result. Dennis.

I don't think I'm going to persue any further but maybe look for a different metal to mix with.

Suggest you create a near 9ct white gold then. It will be very durable and attractive in colour and will not have any problems with melting. Dennis.
