Tempered high carbon steel. We do not think the string will be dented. The balls act like the arms of a collet. Mostly wanted feedback on the Coefficient of friction in regards to using different materials such as copper, aluminum, ceramic, brass, hard rubber. Thanks for the feedback.
I want to use small metal balls to grip a steel wire that is tin plated.
The metal balls are sliding against the tin plated steel wire.
The balls are forced to impinge on the tin plated wire and grip it.
What material or plating for the balls would be best to have the highest possible...
