VBR offers copper-nickel strips in soft, half-hard and hard state according to EN 1652. Each state provides certain characteristics for strips: hardness, tensile strength and elongation.

Hardness - is the value of material hardness. The measurement is carried out according to the Vickers method: determining the hardness of the metal by the size of the impression left by a diamond tip in the form of a quadrangular pyramid, which is pressed into the surface under the influence of the load. It is defined in units of HV.

Tensile strength - that is, temporary resistance - a measurement of the load corresponding to the greatest effort that precedes the destruction of the sample. It is measured in N/mm² (MPa).

Elongation - that is, relative elongation - is a value that shows the percentage by which a material is elongated before it breaks. This indicator is especially important for sheets used for deep drawing. It is measured in %.
