                           Who does not have any ?             


If you like to have a better layer quality then you should know the right material composition. In connection with this information it can be or it is necessary to change your pretreatment steps. In most cases you get a better result than before.

If you want to know the precise composition of various ground materials, contact me and inform me about the material number or the alloy description.

  for example to :


Steel and stainless steel



material No DIN                    from 1.0003 to 1.8956 and comparable international standards


various aluminium alloys with elements like                         silicon, zinc, magnesium, mangan, copper and other
AZ-, AM- and further series


to the main page       to pretreatment

Sintered material steel with extreme pits on and within the surface which in most cases cannot be closed by means of electroplated coatings.Consequences are amongst others blisters.
