Bronze Age. When they used copper-tin, it was so rare almost nobody could afford it. But, when the trade of bronze began, it quickly spread, and it spread so fast that many people could afford to buy it and use it.
Bronze Age (if you're looking for a time period!)

The Egyptians learned about making bronze tools and using chariots from the Hyksos during the Second Intermediate Period. The Hyksos introduced these advancements, which significantly improved Egyptian technology and military capabilities. This exchange greatly impacted the growth and power of Egypt in ancient times.
