Description

Feuerbeständige, bearbeitungsfähige und einen hohen elektrischen Leitungswiderstand aufweisende Eisenlegierung Das Hauptpatent betrifft eine feuerbeständige, bearbeitungsfähige und einen hohen elektrischen Leitungswiderstand aufweisende, insbesondere zur Herstellung elektrischer Widerstände geeignete Eisenlegierung mit bis zu 0,350/0 Kohlenstoff, 2 bis i 2 % Aluminium, i o. bis 3o % Chrom und o,2 bis 3% Kobalt.Fireproof, machinable and high electrical resistance containing iron alloy The main patent relates to a fire-resistant, machinable and having a high electrical line resistance, in particular for manufacture electrical resistances suitable iron alloy with up to 0.350 / 0 carbon, 2 to 12% aluminum, 10 to 30% chromium and 0.2 to 3% cobalt.

Es hat sich nun gezeigt, daß man . die Feuerbeständigkeit, den Leitungswiderstand sowie die Verarbeitungsfähigkeit durch Ziehen; Walzen o. dgl. weiter steigern kann, wenn man den Kobaltzusatz über 3 %, und zwar bis zu 6 0/b erhöht.It has now been shown that one. the fire resistance, the line resistance as well as the workability by drawing; Rolling or the like can further increase, if one increases the cobalt addition over 3%, namely up to 6 0 / b.

Außerdem ist es zweckmäßig, den Aluminiumgehalt _ auf z bis 5% zu bringen.It is also useful to increase the aluminum content to between 2 and 5% bring.
