High-Leaded Tin Bronze
CDA 937
SAE 64 83-10-10
ASTM B505
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 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.

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 interrupted.
