Brass is not an element metal by itself but an alloy of copper and zinc.
This is the most commonly used brass. Used in household plumbing including common items such as taps and hot water piping. Although many different alloy percentages can be found, yellow brass usually contains around 60% to 70% copper, 30% to 40% zinc and trace amounts of lead and tin. Yellow brass prices often reflect the price of copper but demand is also key, as with any alloyed metal.
Although diminishing in use, this brass is still commonly recycled. The reddish pink tint gives this brass its name. The red tint is due to the high amount of copper. Red brass is commonly made up of 85% Copper, 15% Zinc and very small traces of Lead and Tin.
This has largely replaced red brass as we’ve known it. The common element alloys are 80% copper, 10% zinc, 5% tin, 2-3% lead and other trace elements. Its common uses are similar to red brass.
A less common type of metal that has similar alloyed elements as brass, is bronze. The 2 varieties most used are defined as Aluminum Bronze and Manganese Bronze. Aluminum Bronze is around 90% copper, 7% aluminum, 2-3% iron and traces of other elements. Manganese Bronze is 58.5% Copper, 39% Zinc, 1.4% Iron and small traces of other elements.
