OK I know my memory is going so I need help here.
Many years ago I bought some red rod! I could have bought green or black at the time, but the seller at the jumble said it was ok for what I wanted.
I wanted to use the stuff as a bearing surface a bit like an oilite bearing. The job was a drop arm or swing arm pivot on a press.
Now I have finally used up all the red stuff I had and could do with some more, but what was it really called and is the black stuff better?
If one assumes swing arms in cars etc what are they using now?
Resistant to water, chanes in temperature and good impact resistant properties would all be nice to have together with hard wearing of course.
