Cu-ETP is a copper alloy that contains a small amount of oxygen but no phosphorus and is therefore best suited for use in the electrical industry. This alloy has the highest electrical conductivity. Copper content - 99.90%. 

Cu-DHP is a copper alloy that deoxidizes with the addition of phosphorus, that is, there is no free oxygen in copper, as a result, the electrical conductivity of this variety drops slightly. On the other hand, this type of copper is easy to weld and solder due to the lack of oxygen. Cu-DHP is also resistant to hydrogen embrittlement. Copper content - 99.90%. 

Cu-OF is a highly conductive oxygen-free copper with a minimum copper content of 99.95%. It offers the benefits of both ETP electrolytic copper and phosphorus deoxidized copper. The high purity and absence of deoxidizers ensures 100% IACS electrical conductivity, as well as no susceptibility to hydrogen embrittlement. Cu-OF has very good brazing and welding properties, unlike Cu-ETP. 

Cu-OFE - it is an oxygen-free, phosphorus-free copper that contains a minimum of 99.99% Cu. This pupe copper has a minimum electrical conductivity of 101% IACS (International Annealed Copper Standard).  

CuAg0.10(OF) is oxygen-free copper characterized by high electrical and thermal conductivity and resistance to hydrogen embrittlement.

VBR offers copper tubes in soft, half-hard and hard state according to EN 12449, EN 12600, EN 12735 and EN 12451. Each state provides certain characteristics for tubes: 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 %.
