The H62 brass Sheet is an alloy mainly composed of copper and zinc. It is widely used and its properties depend on the ratio of copper to zinc. H62 brass
sheets containing more than 63% copper can be cold worked, can be annealed, and have ductility; while alloys containing less copper and more zinc should
be hot worked and have higher strength.
Since we don't know what methods the ancients used to smelt zinc or zinc ore, it is not clear about the use of H62 brass sheets in ancient times. Zinc has a
lower boiling point than copper. When heating copper, charcoal also heats the zinc ore, making it difficult to prevent the evaporation of zinc. The Romans may
be the first to use this method on a large scale, but the smelting bronzes may have inadvertently produced the H62 brass sheet before, because the difference
between tin and zinc was initially unclear. We should note that the H62 brass sheet mentioned in the Bible is actually bronze; the Roman coin called Hughes is
also cast from copper or bronze instead of H62 brass. To complicate matters, they did use the H62 brass sheet to make coins, but at first the H62 brass sheet
was more expensive than copper or bronze.
However, from the Middle Ages, the H62 brass sheet was a luxury before it was used as a pot and sheet, only for commemorative tombstones and the like.
Since about 1230 AD, H62 brass sheet products have been popular in Europe for about 300 years because they are much cheaper than large sculptures. The
bronze statue of Archbishop Wilpu, who died in 1231, is the earliest bronze statue known to be made of H62 brass. The process of casting H62 brass sheet
products is as follows: first, the pulverized zinc ore and the charcoal are mixed with the copper block to heat, the zinc and copper are combined, and then heated
to melt the alloy, and then the copper liquid is poured into the mold. The first H62 brass sheet in the UK was imported, mainly imported from Tourne. The client
can order a complete tombstone from Tourne that has been placed in a beautiful base or marble base.
