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 for emergency repairs.
