Guter Tip!
Das Material ist in einer lustigen Kategorie eingestellt worden. Für den Gegenwert von 7 Rollen MuMetall bekommt man schon einen EMV-Spektrumanalyzer :shock:

Mu Metall auch mal bei ebay eintippen...da hats auch was....auch kleinere Mengen.

Andererseits schreibt Wikipedia:
"Wenn Mu-Metall gebogen, verformt oder mechanisch bearbeitet wird, bricht die hohe Permeabilität drastisch ein. Werte herunter bis \mu_r=150 sind möglich. Deswegen sollte Mu-Metall nach mechanischer Beanspruchung unbedingt erneut geglüht werden, um durch Ausheilen von Gitterfehlern die hohe Permeabilität wiederherzustellen."

Insofern weiß ich nicht, ob ein Selbstbau (Selbstbiegen) von Trafogehäusen ratsam ist.

Markus, darueber habe ich mich auch gewundert.
Aber im Prospekt steht ja explizit drin, dass man seine Trafos nach dem Einwicklen eben nicht mehr unter Schutzgas
ausgluehen muss. Wie das geht ... ? Vielleicht funktioniert es wegen der geringen Dicke einigermassen. Es geht ja
um Gitterstrukturen, in die dann wieder Fehlstellen kommen, die bei hoher Temperatur wieder ausheilen.
100µ sind aber im Vergleich zu einem atomaren Gitter immer noch recht gross...

Eigentlich[tm] sollte ich das zumindest mal gewusst haben... :oops:

Gruesse

Kurze Frage: sind die Dannerkassetten eigentlich auch aus Mu Metall?
