Our brass product range includes many of the most commonly used grades – from naval brass to high-tensile brass and from dezincification-resistant brass to free-machining brass. These offer a variety of properties such as high strength, ductility, corrosion resistance and machinability. Widely used in almost every industrial sector, brass is the most common of the copper-based alloys.

Brass is an alloy of copper and zinc to which other elements are added. These additions – commonly tin, manganese, arsenic, aluminium, silicon and lead – are usually less than 5% and enhance the individual properties, resulting in a material that is ideal for specific application areas. There are over 40 standard grades of brass with a zinc content varying from around 5-40%.
