Data sheet: Brass tubes

Brass tube is a very versatile product used in a wide range of industrial, construction and decorative applications due to its combination of physical and aesthetic properties. At Bronmetal we supply tubes in different formats that adapt to the needs of our customers: round, square, fluted or rectangular. In our catalogue you will find brass tubes in different sizes and alloys: copper-zinc, copper-zinc-lead and complex copper-zinc alloys which include other elements such as aluminium, nickel, iron or manganese. Each type of alloy has certain characteristics.

One of the main characteristics of brass tubes is their resistance to corrosion. This type of product is particularly suitable for applications in taps and fittings for water and other fluids. It is a material that does not rust easily and maintains all its properties for a longer period of time.
