On the Compositions translation page there are these different alloys:
- 10 aluminium bronze (Q447546)
- 32 copper-aluminium
But the Wikidata page https://www.wikidata.org/wiki/Q447546 say “copper-aluminium” is another name for “aluminium bronze”. It is estrange but… Are these names the same alloy or not?
Perhaps the confusion in Wikidata is due to the fact that bronze is an alloy of copper+tin (10-12%)+other
