If this is not the case, you must clean the contact surfaces. Petroleum and related technologies Shipbuilding and marine structures The contact area should be flat, clean, and uniformly roughened. Do not bend over sharp edges; only perform drilling and punching after bending; 4373 sudden deformation pressure.
In the case of vibrations etc. The tension discs maintain the tension force within a defined range and are therefore also recommended for the fixing of screws. Health care technology However, the contact surfaces should be free of oxidation and grease.
These should be higher strength 4367. Due to the abundance of possible influences during its application, it does not release the processor nor the user from performing their own tests and trials.
Deviating current loads can be converted using the factors listed in DIN The 43763 temperature caries accordingly with higher or lower ambient temperature. The surfaces should be even but not polished. Packaging and distribution of goods Spring washers are preferable for obtaining a constant pressing force during the various thermal stresses.
Glass and ceramics industries Treatment of contact surfaces: Busbars with rectangular cross-section DIN Copper oxide has a considerably lower electrical resistance than aluminium oxide dih a negative temperature resistance coefficient. Therefore, cutting with every second saw tooth produces good results. Rubber and plastic industries The contact will therefore be better if the surface is rough, has pressing lines, or has been knurled.
If the surfaces are pressed together to be connected 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. Due to their higher availability, steel screws are recommended. Log In Sign Up. For a given contact pressure, a copper surface has a contact resistance that is times lower than that of aluminium.
Construction materials and building In fact, no maintenance may be necessary at all. Image Gallery Downloads Request Information. Energy and heat transfer engineering The data in this technical product information is based on our current knowledge and experience.
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.
DIN – European Standards
The creep behaviour of CUAL lies between that of copper and aluminium.
