Characteristic<\/strong>
Commonest, low-budget gun metal alloy for slice bearings. Still has good dry-running
properties and sufficient wear resistance at medium hardness. Also suitable when
unhardened shafts and light edge pressure are being used. Short-chipping material, good
machinability, good corrosion resistance (even in seawater), soft solderable and to a limited
extent hard solderable. The main areas of application are slide bearings and bearing bushings
for general mechanical engineering.<\/p>\n\n\n\n
