Bronzes are copper based alloys with the major alloying element being tin. They offer a combination of properties such as high strength, hardness, corrosion resistance and wear resistance.
Copper aluminium alloys are commonly known as aluminium bronzes. These alloys cover a range of copper-based alloys in which the primary alloying element is up to 14% aluminium.
BSB23 is one of the most popular grades of aluminium bronze with additions of 10% aluminium, 5% nickel and 5% iron to enhance the overall properties of the alloy.
A wrought version of the 10/5/5 aluminium bronze BS B23 is used when the commercial CA104 is deemed not fit for purpose. BS B23 is mainly used in aerospace engineering but is also used in the marine and chemical sectors due to its high strength and excellent resistance to corrosion and erosion in seawater and other aggressive environments. BS B23 is also known for its excellent shock and wear resistance whilst being able to retain its properties at cryogenic temperatures.
