These piston rings are for an air compressor piston 21:27 and in most cases regular grey cast iron is the material of choice as shown by their choice of scrap metal.

[@em4703]

Cast iron is a great piston ring material for automotive too, very low friction compared to other alloys thanks to graphite stuck in its crystalline structure. It's only recently that cast iron was replaced by steel since modern engines are getting smaller and smaller but make more and more power per cc to beat regulations, and steel can resist abuse substantially more, especially when running it thin, again, for "fuel saving" purposes.

[@david929190]

There are many grades of cast iron. A company once went through over 100 variations when designing a sleeve valve aircraft engine.

[@nicksomingenhar]

Even seems like the air compressor piston was also home casted, at least when you look at the last 3 rings the put in, when you get to see the inside of the piston But 3rd world country as we call them, seem to be good at repairing almost everything, if something break, make a new one. should that break, make one more

[@nicksomingenhar]

They also manufactured for early diesel locomotives the delta engines and of course marine engine pistons which were like dustbins.

lol, for an beaten air compressor maybe, but this is not combustion engine piston ring, it is dubiously made, from scrap metal.

Doesn't the mixed alloy variances cause consistency issues from lot to lot? Does that results in significant differences in ring and piston sleeve wear from lot to lot?

[@tonyb7748]

the engines they are making parts for have regular ring replacement procedures. Kind of like buying a KIA in the US and replacing the engine every 30k.

[@Absaalookemensch]

@@tonyb7748 Ahhhhhhh...thank you I'm used to getting 300,000 to 450,000 miles out of a automobile engine, 550,000 to 750,000 on a semi diesel engine.

@@Absaalookemensch thats outstanding! You must have a very good maintenance regimen.

[@Absaalookemensch]

@@tonyb7748 That and I don't treat vehicles like race cars. Those who treat their vehicles like race cars will maintain them as often as race cars require. Even though I normally drive 5 mph over the speed limit, I still get great gas mileage, go 10 years between new brakes in my automatic cars and last traffic ticket was in 1998. Before that was 1987. I was young, stupid and driving a car like a race car. But I learned.

[@akhtarkh]

In most cases, especially this size, the piston rings are made from regular grey cast iron. Their choice of scrap material identifies this. It is quite possible that these rings are for compressors. The piston 21:27 they are using for reference is a double acting piston, meaning that it is most probably for a compressor.

[@bigsquatchsasfoot1964]

Brilliantly done 👍

[@igoraverianov6207]

😀this is how piston rings were made 100 years ago) do not think that you can take any piece of metal and make anything out of it.using modern technologies, the rings are given some ovality and the cross section of the ring is not square but trapezoidal .. in addition, heat treatment is required😁😁

[@terrenceolivido741]

yeah, but all these modern bs. engines will turn to junk. hopefully the old ford straight six can be converted to be repaired like this . ... lol...

[@martinswiney2192]

Actually a great job of making the piston rings. But what purpose can the rings serve on a piston that is full of holes? Not only machined holes but holes in the cast part of the piston

[@slypig24]

I would guess if for test fitting only.

[@robpinter5431]

Oil lubrication, a bit like oil scraper rings in an automotive engine.
