Product show

Copper is the earliest metal discovered and used by human beings. Household utensils, farm tools and coins are all closely related to copper. The use of copper had a profound effect on the progress of early human civilization. To this day, copper is still one of the metals that man cannot live without.

Copper has even become a synonym for money. When ancient literati saw the bad habits of the nouveau riche, they often rolled their eyes and sniffed that copper smelled bad.

The history of human using copper to cast coins has not been new, should be after the use of shellfish, coins with copper was born. This has been handed down from generation to generation. In modern society, copper is used for coinage more than the ancients.

In the application of copper coins, in addition to changing the size, it is very convenient to use different alloy composition, change the alloy color to make and distinguish different denominations of coins. Commonly used are "silver coins" containing 25% nickel, brass coins containing 20% zinc and 1% tin, and "copper" coins containing small amounts of tin (3%) and zinc (L.5%). Thousands of tons of copper are used every year to produce copper coins around the world. The Royal Mint in London alone, which produces 700 million coppers a year, needs about 7,000 tons of copper.
