If you use the silicone RTV mold for making a wax casting, you can use
the lost wax process to cast any metal. If I were doing it, I would
probably just go for silicon bronze. I don't have any way to melt
steel or higher temp metals.

Hello, I want to cast some fine pitch gears in a Silicone RTV mold. I
want to know what the toughest and/or strongest material is moldable
in silicone RTV that would also serve well to make well
detailed,resiliant and strong gears.

Thanks Steve
