B04 is a “GREEN” non-leaded alloy
Copper-Bismuth Bronze C89835 Federalloy III (932 Version)
Bunting continuous cast bronze bars of B04 give superior quality and performance. Continuous casting achieves a high density grain structure, free of porosity, resulting in a reduction of tool wear and component rejects.
Solid and cored bars are stocked in 13" increments and 105" lengths, and are available in other lengths and non-standard sizes. Consider bars for use when you need special bearings, bearings for prototypes, or for emergency repairs.

B04 is used as a no-lead replacement for C93200 material where lead-free material is required. Properties are similar to the C93200 material however; bismuth does not lubricate as well as lead so a constant supply of lubrication is recommended when using this material. Bunting also produces lead-free materials that replace C83600, C84400, C93700, C93800 and C94500 with bismuth alloys.
