Does anyone know what kind of metal Framus tone rings are made of? A magnet isn't attracted to it so it's not a ferrous metal like steel. Magnets aren't attracted to stainless steel, but I doubt it's stainless. Can't be pot metal, it's too heavy. Wonder if it's brass?

Scratch a small spot & look for a brass color. ( I have several Framus instruments, & like them . I have never seen one of these hoops degrade in the way that Zinc products tend to do.)

I did that and it's just more of the same shiny chrome looking material. I actually used a dremel tool to grind down the 12 casting marks (on the bottom of the tone ring) so it would set completely flush on the pot it's the same chrome looking 'color'. A mystery...

The picture is of the bottom of the tone ring.

I just got a Framus banjo and was wondering the same thing. It has an all metal pot, the rim flange and "tone ring" are all a single piece of metal. It has some brown/red corrosion so I thought it was ferrous but it doesn't stick to a magnet so I don't know.

They sure ring like bell brass.

I have one and always thought it was Aluminum.

WAY too heavy to be aluminum and the tone would be nonexistent.

I always thought that it was some tin alloy.

I'd guess German silver; copper, zinc, and nickle.

Yes, definitely an alloy of some sort, too heavy to be aluminum but polishes more like aluminum than something nickel plated.
