Data sheet: Copper alloy tubes

Bronmetal supplies high quality alloyed copper tubes for electrical, industrial and general applications. In our catalogue you will find a wide range of sizes, diameters and wall thicknesses for the two types of alloys we have available. The two variations of alloyed copper tube we offer are composed of copper, nickel, iron and manganese in different proportions. This alloy is characterised by good corrosion resistance and durability. It is commonly used in industrial applications where some material malleability is required.

In the technical data sheet section you will find the mechanical characteristics according to the type of alloy, the equivalences depending on the applicable regulations and the tolerances of the average diameter, the nominal wall thickness, as well as the tolerances for tubes in coils and spools.
