High-Leaded Tin Bronze
Bunting continuous cast bronze bars of C93200 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.
