Phosphor Bronze 6" x 8" Spring Temper
Phosphor Bronze sheet
This alloy is used most commonly in the cutlery industry for folder washers. This is Spring Temper hardness (nearly full hard) and c510 alloy. I bought 3 large coils in .005", .010" and .015" and cut them into 8" lengths so those that wanted to can make their own folder washers. You might consider getting a sheet of each size just in case.
