C90700 is a “GREEN” non-leaded alloy
Tin Bronze
CDA 907
SAE 65 89-11
ASTM B505

Bunting continuous cast bronze bars of C90700 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 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: 88.00 – 90.00%
Tin: 10.00 – 12.00%
Lead: 0.50% max.
Zinc: 0.50% max.
Physical Properties: Continuous Cast
Tensile Strength PSI: 40,000 min.
Yield Strength PSI: 25,000 min.
Elongation: 10% min.
Brinell Hardness (500 kg load): 100 typical
Machinability Rating: 20
Minimum Operating Temperature: -450°F
Maximum Operating Temperature: 550°F

C90700 is used for bearings and gears where higher strength and load-carrying ability is required. C90700 has good wear resistance but should be used with hardened steel shafts (300-400 HB). Due to the lack of lead, this material requires constant lubrication, generally grease.

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