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.

Typical Properties: (Not to be used for specification purposes.)
Copper: 78.00 – 82.00%
Tin: 9.00 – 11.00%
Lead: 8.00 – 11.00%

Physical Properties: Continuous Cast
Tensile Strength, PSI: 35,000 min.
Yield Strength, PSI: 20,000 min.
Elongation: 6% min.
Brinell Hardness (500 kg load): 60 typical
Machinability Rating 80
Minimum Operating Temperature -450°F
Maximum Operating Temperature 500°F

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.

WARNING: This product can expose you to chemicals including nickel & lead, which is known to the state of California to cause cancer and lead, which is known to the state of California to cause birth defects or other reproductive harm. For more information, go to www.p65warnings.ca.gov.
