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.
