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 general

machine construction.

After these tests at company Wolf, it's obvious that the cheeper bronze bushes wich we have in programm

exhibit less wear and tear than the customary in trade lubrication bushes.
