As a follow-up to this post, I'm looking for material recommendations for a simple ring I intend to use between a nut and fixed component, where the nut, due to threads, will exert a force on the fixed component once the nut is tightened. Purpose of the ring is to act as a sort of sacrificial ring, that will prevent any wear on the twisting nut or underlying fixed component. Ideally, rings should be easy replaceable and cheap.
Nut and fixed component are of the same material, have a hardness ~ 180 BHN, and will see temperatures up to max ~ 950°C. The material I'm looking for should hence be soft, be able to withstand some bearing stress at temperature (albeit low), and can withstand high temperatures. The lubricating action of the ring's material is probably out of the question, and can be accomodated by other means (e.g. anti-seize).
Bearing bronze alloys (like RG7 or phosphor-bronze CuSn8) are ideal materials for bearing applications, but wont handle these temperatures.
Any thoughts?
