Summary for anode basket material Discussion
Anode basket material for MSA lead-tin baths is discussed with some disagreement about whether baskets should be used at all. Reynaldo Arroyo asked what material would be best for 1-inch tin-lead anode balls in a basket. Chris Snyder advised against changing to baskets, saying it is easier to remelt the anodes into slabs and that he never found a basket material that worked well without breaking down at a reasonable cost. Benny Lim said his shop normally used titanium baskets for anode balls, and also suggested using tin-lead alloy anodes instead of pure tin to reduce chemical cost. In a later tin-plating question, an answerer noted that tin anodes are often used as corrugated cylinders hanging from steel hooks, with no basket at all. Overall, the thread leans toward either using titanium if baskets are required or avoiding baskets and using slab/cylindrical anodes instead.
Q. I work for the plating field, specifically with sulfamate nickel and MethaneSulfonic tin-lead plating baths. I have been using pure tin anode bars in the tin-lead baths. I am planning to change the anode bars to anode-balls (1 inch diameter) in a anode basket. What would be the best material to use to make my baskets?

Simply, I would not change to any type of basket, easier to just remelt the anodes into slabs, never found any material that worked or didn’t break down quickly at a reasonable cost.

A. Reyanldo,
We normally used titanium basket for the anode balls.I do not understand why you use pure tin anode for tin lead plating,I suggest you used the tin lead alloy anode,this will save the chemical cost significantly.

Q. What is the anode basket material for tin plating
We are doing tin plating on copper (we have an automatic rack tin plating line). As we do tin plating on copper bus bar, I need information about the anode basket material for tin plating that is suitable for the plating process and does not contaminate the tin plating tank.

A. Mr Snyder has good advice.
The way I’ve seen tin anodes is as corrugated cylinders about 5 feet long. There is no basket – the anode hangs from a steel hook threaded into the tin that hangs right from the busbar.
