Attributed to Aert van Tricht, Limburg (Netherlands), c. 1500. Brass is an alloy of copper and zinc, in proportions which can be varied to achieve different colours and mechanical, electrical, acoustic and chemical properties, [1] but copper typically has the larger proportion, generally 66% copper and 34% zinc.
The most prevalent variety of alpha brass is made up of 30% zinc and 70% copper. This brass alloy, often known as 70/30 brass or ‘cartridge brass,’ has the optimal strength and flexibility for cold drawing. It also has a higher corrosion resistance than brass, with a higher zinc content.
Brass, alloy of copper and zinc, of historical and enduring importance because of its hardness and workability. The earliest brass, called calamine brass, dates to Neolithic times; it was probably made by reduction of mixtures of zinc ores and copper ores. Learn more about brass in this article.
Jul 9, 2023 · The properties of brass can be altered by incorporating various metals into its composition. The chemical composition of the material can lead to variations in its color, hardness, texture, strength, and resistance to corrosion. Typically, brass exhibits a warm and golden hue.
Aug 30, 2008 · Brasses are copper zinc alloys with a wide range of engineering uses. The addition of zinc to copper raises the strength and gives a range of properties, and the brasses are a very versatile range of materials.
Jan 27, 2019 · Brass is any alloy consisting primarily of copper, usually with zinc. In some cases, copper with tin is considered a type of brass, although this metal historically has been called bronze. This is a list of common brass alloys, their chemical compositions, and the uses of the different types of brass. Read More.
Apr 8, 2021 · Modern brass is 67% copper and 33% zinc. However, there are types of brass with copper ranging between 55% and 95% by weight, with zinc ranging between 45% and 5%. Some types of brass contain around 2% lead. Lead improves brass machinability, but the toxic metal readily leaches from the alloy.
