LB4 is an ideal product for producing bearings for non-critical applications
Like LB2, LB4 is an ideal product for the production of bearings, particularly in environments where a general lack of lubrication and where alignment issues are present. This leaded bronze product contains approximately 5% tin and 9% lead. The alloy benefits from excellent machinability with medium strength and good corrosion resistance. LB4 is classed as a general bearing alloy with reasonable ductility which is suitable for use in non-critical applications under low loads.
Commercial applications for this engineering material include:
We stock LB4 in flats, round bar, round tube and hollow bar.
Our knowledgeable staff and resident metallurgists will be pleased to assist you further on any technical topic. Smiths Metal Centres Limited also boasts an in-house UKAS Accredited Testing Laboratory which is unique within the multi-metal and plastic stockholding sector. We believe this underlines our total commitment to quality and our ethos of being the complete service provider.
