It is a dimensionally stable, hard plastic with high abrasion resistance and a low coefficient of friction.
The reason to use it is that currently available pattern steering arm balls are worn out very quickly by the hard steel bearing cups (someone will jump in here and tell me I'm wrong of course). At £100 to £120 per pair this is not good.

I'm not going to say you're wrong, but I'll add this bit of food for thought. Speaking to my local engineering shop, he says that is is his experience it is often the harder surface in a bush or plain bearing that wears fastest. The theory being that any dirt that gets into the joint embeds itself in the softer surface which then acts as an abrasive against the harder surface. What happens in the case of an immaculately clean joint I don't know. But I do know my balls are going oval!

I would prefer to produce a bolt in replacement for the steering arms and track rod adjusters based around high quality M14 rose joints but that would cost me about a £1000 in design costs, laser cutter programming and tooling. The kit would sell for around £150. The kicker would be that replacement rose joints cost around £8. However, my experience of doing this sort of thing is that whatever 2CV enthusiasts say at the time, when it comes to pony up they won't pay that sort of money for non-standard parts.
