BRASS The Poorer Man's GOLD

In the lands now known as Syria and eastern Turkey ancient metalworkers would melt copper with tin to make bronze way back around 3000BC. By accident or by chance they also made brass. Easy to mistake, tin and zinc ore deposits have similar colours and properties.

Around 20BC, metalworkers on the Mediterranean Sea were able to distinguish zinc ores from those containing tin and began blending zinc with copper to make brass coins and other items. Archaeology shows in about 300 A.D. the brass metalworking industry was flourishing in the lands of what is now Germany and The Netherlands.

The main component of brass is copper. The amount of copper varies between 55% and 95% by weight depending on the type of brass and its intended use. When recycled scrap is used, the percentages of copper and other materials in the scrap needs to be known so that the manufacturer can adjust the amounts of materials to be added in order to achieve the desired brass composition. The higher the percentage of copper gives name to surrexerunt auri or ‘rose gold’ as the pinkish tinge of copper shines through giving a very unique appearance.

The second component of brass is zinc. The amount of zinc varies between 5% and 40% by weight depending on the type of brass. Brasses with a higher percentages of zinc are stronger and harder, but they are also more difficult to form and have less corrosion resistance.

The poorer man’s gold. Brass is used in place of gold for decoration with its bright gold-like appearance. Seen on doorknobs, cabinetry, and extensively in brass musical instruments such as horns and bells where a combination of high workability and durability is desirable.

With a combination of strength, corrosion resistance, and formability, brass will continue to be a useful material for many applications in the foreseeable future. Brass also has an advantage over other materials in that most products made from brass are recycled or reused, rather than discarded in a landfill, which will help ensure a continued supply for years to come.
