The damage to the big end bearing of the connecting rod is as shown, with a copper content of 74% detected. Does large-head tile contain copper components?

If there is no copper component, then where does this copper come from?
Bearing bush components are composed of alloys such as copper, tin, lead, antimony, etc
What was said upstairs is correct~~ Copper is one of the components involved~~~~~~~~~
Is it the small-end bearing that supplies oil, as wear in the small-end bearing causes oil to reach the large-end bearing?

It’s not just this point that’s damaged; all the moving parts such as the connecting rods, crossheads, and piston bodies should be disassembled for inspection and maintenance.
The positioning ring of the large-head tile is worn out; the positioning ring is made of copper
