High-Leaded Tin Bronze
SAE 64 83-10-10
Bunting continuous cast bronze bars of C93700 give superior quality and performance. Continuous
casting achieves a high density grain structure, free of porosity, resulting in a reduction of tool wear and
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.

C93700 has higher tin and lead than C93200 and is used in bearings with higher speeds and loads. It
has increased corrosion and oxidation resistance, with good anti-frictional properties, good load-carrying
ability and excellent machinability. C93700 can be used in applications where lubrication may be low or
