AMAG ProCath®
Basismodul

AMAG primarily uses 1050 and 1070 series pure aluminium as basis material for cathode sheets while 1200 material is also employed. The excellent flatness of the sheets and the additional hardening during the production process improve handling of the sheet during the stripping of the zinc layer. Furthermore this quality advantage also provides greater brasion resistance (important with regard to the stripping process), as well as the delayed onset of corrosion.

AMAG ProCath®
Edge strip

The unique edge strip application process developed by AMAG is well known on the market and used by several customers worldwide. In particular, this state of the art application is characterized by the fact that it works without the support of either adhesive media such as silicon or hot melt glue nor mechanical anchorage. 

 

Customer feedback showed that under normal operating conditions, edge strip adhesion often exceeds the life time of the sheet. The above average adhesion of AMAG’s edge strips helps to increase the lifecycle of the cathodes. This reduces the total costs of ownership especially by cutting down the costs for maintenance and further manufacturing steps.

AMAG ProCath®
Liquid Zone Protection

The Liquid zone Protection increases the life time of the sheets while protecting the area directly above the liquid level from corrosion. It resists the extremely aggressive atmosphere due to the sulphuric acid spray mist. Normally the accelerated corrosion in this area is limiting the life time of the cathode sheet. However, as the LZP and the edge strip are based on the same technology, the LZP shows an unusually tight bonding to the aluminium surface, too.

AMAG ProCath®
Stripping Insert

AMAG offers a unique patented stripping insert which combines special materials with join-technology used in the aircraft and automotive industry. Through the use of this process AMAG is able to offer customized geometries next to the standard circular shape.

AMAG ProCath®
Hanger Bars

Generally a AA-6005 extruded profile in temper T6 is used for this purpose. Welding on the cathode sheet can either be done conventionally or by friction  teer welding.

 

Friction steer welding offers benefits in terms of mechanical properties as well as chemical resistance and due to the lower heat impact does not harm the plastic components.

AMAG ProCath®
Al-Cu-Contact

Depending on the requirements of the customer AMAG can offer either state of the art explosion bonded contacts or unique friction steer welded contacts.
