If the surfaces are pressed together to be dkn without the Vaseline being removed, the excess Vaseline is pressed out and contributes to the sealing of the connection and to the protection against harmful effects.

When the temperature rises, the conductivity of a connection between two oxidized copper surfaces increases. Audio and video engineering You must have JavaScript enabled in your browser to utilize the functionality of this website. Image Gallery Downloads Request Information.

Recommendation for drilling Cutting speed: Materials handling equipment Do not bend over sharp edges; only perform drilling and punching after bending; avoid sudden deformation pressure.

The template should be as close as possible to the shearing edge so that the material is adequately supported.

Copper-Aluminium Bars (CUAL)

Rubber and plastic industries Log Vin Sign Up. Mechanical systems and components for general use Health care technology In a completed connection, the actual contact area is significantly smaller than that of the total surface area of the connection. Depending on the individual case, we recommend consulting with us. Petroleum and related technologies They ensure the different expansions between the screws and the bar and compensate for any potential relaxations dkn the metal.


It is generally advisable to tighten non-rusting screws with a torque wrench. 46373 for the tightening of the screws and dimensions of the washers Screw dimensions. CUAL can be cut using the same method as aluminium. Sufficient tension force prevents the screws from loosening by themselves. Latest News of the Blog. DIN and Recommendations for cutting Cutting speed: Exaggeratedly flat surfaces are not necessary for the connection, since the connection is clean and fixed.

Road vehicles engineering Copper oxide has a considerably lower electrical resistance than aluminium oxide and a negative temperature resistance coefficient. The surfaces should be even but 4363 polished. It is important that the yield strength of the material is not exceeded; a contact pressure of max.

DIN – European Standards

Drilled holes and screw connections for busbars; Channel section busbars. The contact area should be flat, clean, and uniformly roughened. In order to ensure good electrical contact between the busbars, it is necessary to penetrate the surface film of oxides, sulphides, and other contaminants.

The contact between the surfaces is initially limited to the tip of each surface, which are therefore subjected to a significantly higher pressure than the average pressure of the connection. Deformations 433673 occur during the binding process.


The screws can be made of a wide variety of steel grades, brass, or bronze. Packaging and distribution of goods In the case of vibrations etc. Shipbuilding and marine structures 43637, the contact sin should be free of oxidation and grease. Sciences humaines et sociales, lettres. You have no items in your shopping cart. Alert me in case of modifications on this product contact us. Domestic and commercial equipment.

Since CUAL has a copper plating, it has the same outstanding contact properties as copper, and so CUAL bars can be used in the same way as copper bars.

A legally binding guarantee of certain properties or of suitability for a specific purpose cannot be derived from our information.

ISOFLEXX® Classic Ampacity

CUAL can be tin- and silver-plated.
