There is a lot of talk, books, and science about the development of iron into increasing qualities and types of steel, but I do not see the same attention given to bronze. This is not counting the development from copper into bronze near the start of the bronze age, as that is commonly taught in some detail. However, such articles often stop at the point of the development of bronze, and so give the impression that once they had bronze, it never got better. Or at least, it is left rather mysterious as to how much better it got through history.
By the end of the bronze age, around 500 to 300 BC, did bronze metallurgical quality peak (assuming it did not reach peak quality earlier)? Or did bronze continue to get better and stronger, even in the iron age?
As an example, was bronze of a far higher quality in the modern era, with fewer impurities, and higher strengths and tolerances? Or was it very similar to ancient examples of the metal?
