Better corrosion resistance than tin bronzes with lower tin content, higher strength and very good sliding properties and wear resistance. Good cold formability, good solderability. Sliding components, slide bearings (especially thin-walled ones) and sliding guides. Highly stressed worm and gear wheels, screws and bolts. |
