Copper bar

Volyn' Biznes Resurs offers copper bar in stock and for production.

Cu-ETP is a copper alloy that contains a small amount of oxygen but no phosphorus and is therefore best 

for use in the electrical industry. This alloy has the highest electrical conductivity. Copper content - 99.90%.

The copper bus is manufactured according to the European standard EN 13601 "Copper rod, bar, and wire for general electrical purposes".

VBR offers copper tire in soft, half-hard and hard state according to EN 13601. Each state provides certain characteristics for tires: 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 %.

The tire comes with sharp, rounded or half-round edges.

Sharp corners (SH) of a tire with a square, hexagonal or rectangular cross-section shape with the following characteristics:
      corner rounding radius from 0 to 0.8 mm
      nominal thickness or cross-sectional width of more than 0.5 to 80 mm

The rounded corners (RD) of the tire must meet the following characteristics:
      radius of rounding from 0.5 to 2.5 mm
      nominal thickness or thickness of the cross section over 0.5 to 80 mm

The radius of the semi-circular edges (CE) of a tire with a rectangular cross-section (Fig. 3) is equal to half the thickness and must correspond to the maximum deviation +/- 20% of the radius. The rounding line should smoothly connect adjacent surfaces and should be free of sharp, rounded and protruding corners.
