I'm afraid I know nothing about which pre-Columbian cultures had any metalworking, but I can answer why metallurgy was, in 1492, very rare in the Americas but widespread in Eurasia.
Paraphrasing liberally from Guns, Germs and Steel, which I happen to be reading at the moment, Native American peoples were largely hunter-gatherers. Metalworking, like any specialised trade, is very unlikely for hunter-gatherer cultures, as having the time for individuals to develop craft specialisms requires a food surplus that can usually only be generated from agriculture, plus hunter-gatherer cultures are often nomadic, which rules out heavy metalworking equipment.
The reason why Native American peoples were hunter-gatherers is the premise of the bulk of the book. To oversimplify, there were two main factors:
Almost all the large mammals died out from the Americas after the last Ice Age, meaning there were no domesticable animals (to pull ploughs and provide transport) until the arrival of horses with the Europeans. At the same time, there were much fewer useful seed-plants (with high protein content, as well as digestible carbohydrates) in the Americas, compared with all the grasses from the Near East.
(As well as a lack of domesticable animals impacting on the productivity of farmland, it is thought that this also led to a greater preponderence of disease in Eurasia (plague, smallpox, measles etc), meaning that we were more likely to have inherent immunity, whereas Eurasian diseases could ― and did ― decimate the aboriginal inhabitants of the Americas.)
Eurasia is longer on an east–west axis, whereas the Americas (and sub-Saharan Africa) are longer north–south. The east–west axis means that animals and plants can spread to areas of similar latitude (and, thus, of similar climate). The deserts and rainforests in the Americas, and the narrowness of the isthmus at Panama mean that domestication of plants and animals took an exceptionally long time to travel to other parts of the continent.
So, with neither domesticable animals nor usable crops, the hunter-gatherer cultures in the Americas did not have the food surpluses that are a prerequisite for specialised crafts, particularly metallurgy.
