Advantages of bronze bushes compared to lubricating bushes
Short cut: | CuSn7Zn4Pb7-C |
Material number: | 2.1090 |
Density: | 8,83 Kg / dm³ |
Composition: | copper 81-85% / nickel to 2% / phosphor to 0,1% / lead 5%-8% / tin 6%-8% / zinc 2%-5% |
Notes to characteristics and use:
- Common and favourable red brass alloy for slide bearings.
- With medium hardness it still has good running qualities and sufficient resistance to
- wear and tear. It’s also suitable when non hardened shafts are used and the
- selvedges are slightly compressed.
- Good corrosion resistance (even in sea water).
- Main range of applications are bearings and bearing bushes for genera
- machine construction.
