Description

Kupfer-Nickel-Legierung Die vorliegende Erfindung bezieht sich auf eine aus Kupfer, Eisen, Nickel, Silicium, Magnesium und Aluminium bestehende Legierung folgender Zusammensetzung Kupfer........................................ 50°l0 , Nickel......................................... 28u, Eisen.......................................... i9 Silicium ...............:....................... 2 °@ Aluminium 1 ................................... Magnesium In dieser Legierung dient das Nickel zur Vermeidung der Oxydation und (in Verbindung mit Eisen) zur Erzielung eines beständigen Spiegelglanzes.Copper-nickel alloy The present invention relates to an alloy of copper, iron, nickel, silicon, magnesium and aluminum of the following composition Copper ........................................ 50 ° l0 , Nickel ......................................... 28u, Iron .......................................... i9 Silicon ...............: ....................... 2 ° @ Aluminum 1 ................................... magnesium In this alloy, the nickel serves to avoid oxidation and (in conjunction with iron) to achieve a permanent mirror finish.

Eisen und Kupfer bewirken die mechanischen Eigenschaften, durch die sich die Legierung von anderen bekannten Legierungen unterscheidet.Iron and copper cause the mechanical properties through which the alloy differs from other known alloys.

Magnesium, Silicium und Aluminium dienen zur Erzielung einer vollkommenen Homogenität, Nichtrostbarkeit, Schwefelfreiheit und guten Gießfähigkeit der Legierung.Magnesium, silicon and aluminum are used to achieve a perfect Homogeneity, rustproofness, freedom from sulfur and good castability of the alloy.

Eine derartige Legierung hat gegenüber anderen Legierungen folgende Vorzüge: a) erhöhte Biegsamkeit, b) Walzbarkeit, c) Beständigkeit gegen Säuren und Alkalien, Seewasser, Salzlaugen und Oxydation, d) hohe Druckfestigkeit, e) hohen Dehnungswiderstand, f) große Brinellhärte. Die Legierung läßt sich durch einfaches mechanisches Schleifen auf beständigen hohen Spiegelglanz polieren und dadurch die Vernickelung oder Verchromung durch Elektrolyse ersparen.Such an alloy has the following over other alloys Advantages: a) increased flexibility, b) rollability, c) resistance to acids and Alkalis, sea water, brine and oxidation, d) high compressive strength, e) high Resistance to elongation, f) great Brinell hardness. The alloy can be simply mechanical grinding to a permanent high mirror finish and thereby the Save nickel or chrome plating through electrolysis.

Die mechanischen Eigenschaften sind erhebliche: Druckfestigkeit . . . . . _ . 55 kg/cm-Dehnungswiderstand ..... 2o Brinellhärte . . . . . . . .. . . . _ i 5o.The mechanical properties are significant: compressive strength. . . . . _. 55 kg / cm stretch resistance ..... 2o Brinell hardness. . . . . . . ... . . _ i 5o.

In einer derartigen Legierung kann das Nickel auch durch Chrom ersetzt sein.In such an alloy, the nickel can also be replaced by chromium be.
