Description

Kupferlegierung Die bekannten Metallegierungen auf Basis Kupfer, beispielsweise solche mit bis zu i z a/o Zinn, bis zu 50116 Nickel, bis zu 2 0'o Eis-en und im Rest Kupfer und die üblichen Verunreinigungen erstarren meist verhältnismäßig grobkörnig, so daß sie gegen hohe Schlag-und Druckbeanspruchung nicht genügend widerstandsfähig sind. Es zeigte sich nun, daß sich die Festigkeitseigenschaften dieser Legierungen ganz erheblich verbessern lassen, wenn man ihnen Birnen Zuschlag von bis zu 30'o Tantal und/oder Niob gibt. Dadurch erhalten die Legierungen ein sehr dichtes, feinkörniges und sehniges Gefüge, so daß sie sich nicht nur für die Herstellung von Lagern mit hohen Druckbeanspruchungen und überhaupt für Teile, die einem Verschleif') durch Reibung ,ausgesetzt sind, eignen, sondern auch für die Herstellung von Gegenständen mit .einer- besonders guten Korrosionsbeständigkeit, insbesondere mit hoher Säurebeständigkeit. Dabei kann man das Zinn in den Legierungen auch ganz durch Mangan :ersetzen oder unter Beibehalt der sonstigen Legierungsbestandteile durch bis zu 40/0 Silicium und bis zu 400110 Zink. Da Tantal in der Natur immer mit Niob zusammen vorkommt, der Einfluß der Stoffe auf die Metallegierungen auf Basis Kupfer aber bei Gehalben bis zu ; % in gleicher Richtung wirkt, ist @es aus wirtschaftlichen Gründen zweckmäßig, keine Trennung der Metalle Tantal und Niob vorzunehmen. Es hat sich auch gezeigt, daß .es von Vorteil ist, eine Ferrolegierung mit möglichst hohen Gehalten an den Metallen Tantal und Niob zu verwenden.Copper alloy The known metal alloys based on copper, for example those with up to i z a / o tin, up to 50116 nickel, up to 20'o iron and im The remainder of copper and the usual impurities usually solidify in a relatively coarse-grained manner, so that they are not sufficiently resistant to high impact and compressive stress are. It has now been shown that the strength properties of these alloys Can be improved quite considerably if you give them pear surcharge of up to 30'o Tantalum and / or niobium. This gives the alloys a very dense, fine-grained appearance and sinewy structure, so they are not just suitable for making bearings with high pressure loads and generally for parts that are subject to wear and tear Friction, exposed, are suitable, but also for the manufacture of objects with .einer- particularly good corrosion resistance, especially with high acid resistance. The tin in the alloys can also be completely replaced by manganese: or while retaining the other alloy components with up to 40/0 silicon and up to 400110 zinc. Since tantalum always occurs together with niobium in nature, the influence of the substances on the metal alloys based on copper but at salaries up to ; % acts in the same direction, @it is advisable for economic reasons, to not separate the metals tantalum and niobium. It has also been shown that it is advantageous to use a ferro-alloy with the highest possible levels of Use metals tantalum and niobium.
