High-Leaded Tin Bronze
CDA 938
SAE 67 78-7-15
ASTM B505

Bunting continuous cast bronze bars of C93800 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 formore emergency repairs.

C93800 is similar to C93200 but the higher lead content improves the machinability and frictional properties. C93800 can be used in applications were lubrication may be interrupted without seizing. Bunting also produces other high-leaded alloys including C93400, C93600, C93700, C93900, C94000, C94100, C94300, C94400 and C94500.
