Platinum Clad Anodes Description
SAM Products is the leader in platinum clad anodes (platinized anodes). If you know the type of anode you are interested in, please contact us directly. If you are unsure about the type of anode you need, please use the guides below.
Platinum is used on the surface as a primary anode material due to its excellent corrosion resistance under anodic conditions coupled with its ability to pass current in all electrolytes without forming an insulating film. The corrosion resistance of platinum manifests itself in its low consumption rate. Its major disadvantage is its high cost, making it clear that it is most desirable to use as little platinum as necessary. To restrict the amount of platinum used and to maintain an anode of some structural integrity, it is necessary to use some type of substrate material.
|
Copper (Cu)
|
Good conductivity, low cost.
|
|
Niobium (Nb)
|
Passive film formation, high cost, high breakdown potential, fair conductivity.
|
|
Titanium (Ti)
|
Passive film formation, low cost, low breakdown potential, poor conductivity.
|
|
Platinum (Pt)
|
High corrosion resistance, high cost, good conductivity.

Platinum Clad Anodes Specifications
In order to provide faster service and greater economy, SAM manufactures a number of "standard" anode configurations. These configurations are the result of several years of customer interaction, such that the anode designs could provide sufficient design flexibility for the engineer in a large variety of cathodic protection applications.
