TiCu Clad anode

The professional connection to the power supply is a constantly recurring question in dealing with titanium clad copper bars.

Electrical specialists often plead for the removal of the more poorly conducting titanium from the the contact surfaces.

In order to guarantee optimal current transfer, the connection surfaces are cleaned of titanium by milling or turning. This is a correct method with respect to the electrical conductivity of copper (58 mS) compared to titanium (2.2 mS).

This means that a copper wire with a length of 58 m and a cross section of one square millimeter has a resistance of one Ohm. With titanium the resistance of one Ohm is already achieved at a length of 2.2 m.

However practice shows that environmental influences must be taken into consideration.

When the contact surfaces are cleaned of titanium, the copper is now exposed to corrosive media like aggressive acids, steams and condensates in the galvanic treatment. 

The copper then gradually corrodes resulting in point contact on the contact surfaces and bad current transfers.
