But some pure metals – gold, silver, and copper – were used before then, and the alloy bronze is thought to have been discovered by the Sumerians around 3500 BC But aluminum, one of the most essential metals in modern use, wasn’t discovered until AD 1825, and wasn’t commonly used until the 20th century! Corrosion: Process & Prevention
Gold, Silver, Platinum, Palladium and Titanium are precious metals, meaning they are rare metallic chemical elements of high economic value, shiny, hard, strong with high melting points They form alloys (mixtures) with other metals and this makes them ideal for jewellery
Sep 23, 2015· In the late 19th century, tin foil was commonly used to wrap food products, but has since largely been replaced by aluminum foil Tin can also be alloyed with copper to produce tin brass and bronze Don’t have time to read the blog?
