Looser Bronze 50 (LB 50) - CuSn7Zn4Pb7-C-GS/GC/GZ DIN EN 1982

Looser Bronze 50 is a medium-hard multi-material tin bronze with a dense structure, good emergency running properties and high wear resistance. It can withstand high surface and frictional pressure. LB 50 is manufactured exclusively by centrifugal and continuous casting. The use of these modern casting techniques gives it a fine-grained structure. Looser Bronze 50 is resistant to seawater.

 

As a bearing material, LB 50 is superior to the sand-cast alloy GBz 14, which was long regarded as the best bearing bronze. Both qualities have comparable mechanical properties, but the sliding and emergency running properties of Looser Bronze 50 are significantly better.

 

With hydrodynamic lubrication and sliding speeds of up to v = 8 m/s, it can withstand loads of up to 12 N/mm2.

Die Verwendung von Blei in Nichteisen-Metallhalbzeugen wird bereits seit vielen Jahre reguliert. Die Informationspflicht durch REACH basiert nicht auf
neuen wissenschaftlichen Erkenntnissen.

Gegenwärtig bleibt Blei ein wichtiges Legierungselement für Kupferlegierungen. Bleihaltige Werkstoffe sind langerprobte Legierungssysteme, die eine
Reihe technologischer Vorteile bieten. Blei erhöht u.a. die Gleit- und Notlaufeigenschaften, verbessert die Zerspanbarkeit sowie die
Korrosionsbeständigkeit vom fertigen Bauteil.

Wir bieten aus unserem Sortiment eine ganze Reihe von alternativen Produkten, welche einen Bleianteil unterhalb der Zulassungsgrenze aufweisen.

Wir beraten Sie gerne.
