Zamak 5 has the same composition as zamak 3 with the addition of 1% copper in order to increase strength (by approximately 10%), hardness and corrosive resistance, but reduces ductility. It also has less dimensional accuracy. Zamak 5 is more commonly used in Europe.

History of Zinc
Centuries before zinc was discovered in the metallic form, its ores were used for making brass and zinc compounds for medicinal purposes. Zinc compounds were in the ores smelted certainly as early as 200 B.C. to obtain copper and which gave alloys of copper and zinc – the brass family. The Romans certainly were major users of brass. The Greeks also appeared to know zinc, even if not by name.
An ancient idol, containing 87.5% zinc, found in prehistoric ruins in Transylvania in Eastern Europe is the oldest known zinc object. Zinc filled silver bracelets dating back to 500 B.C. have been found on the island of Rhodes, and the Romans used a zinc alloy to fabricate coins.
Some credit India with developing the first knowledge of true zinc smelting while others attribute its discovery to the Chinese. The production of metallic zinc occurred much later than other common metals. Copper was smelted from its ores around 5000 B.C., lead about 4000 B.C. and iron about 2000 B.C., while zinc appears to have become available on a commercial scale in the 14th century A.D.
In Europe, zinc probably became first known through its import from India and China. Zinc was recognized in Europe as a separate metal in the 16th century when Agricola (1490 – 1555) and Paracelsus (1493 – 1541) wrote of a metal called “zincum.”
Commercial smelting of zinc began in Europe in the middle of the 18th century when the first European zinc smelter was established in Bristol in the United Kingdom using a vertical retort procedure. But the real advent of modern techniques dates from the introduction of the horizontal retort process in the early 19th century. In 1836 hot-dip galvanizing – the oldest anti-corrosion process – was introduced in France. Zinc smelting in the United States started in 1850s.
