A. You can't use titanium. It dissolves. You need zirconium. Ask any reputable basket manufacturer. Vulcanium was one source a few years back.

Use a carrier above solution. Anders S  Anders Sundman 4th Generation Surface Engineering Consultant - Arvika, Sweden 2000 A. Mr. Lynch: My experience with titanium baskets is that they eventually break down and the spot welds give out. What we incorporate now is slab anodes hung inside a polypropylene 3" x 6" x 36" basket, covered with a napped poly anode bag that hangs on the anode bar. This works well in the sense that when they need to be pulled and scrubbed most of the smut stays in the bagged basket. We have not had a roughness problem in our 4 tin baths in 5 years. For the small spears from depleted anodes we use a plastic mesh anode basket with a zirconium anode mesh pad inside. If you need more info I will have our supplier contact you.

We are considering having complete zirconium anodes and cooling coils fabricated, but this would seemingly be an excellent alternative to ensure we get full use of our anodes.

I don't know if Ken is still around and in a position to help all these years later, but hopefully someone will :-) Luck & Regards, Ted Mooney, P.E.
