Why continuous-cast stock
Consistent material for repeatable machining.
Continuous casting solidifies bronze through a controlled die and
withdrawal process. The resulting stock is selected for a dense,
consistent structure that supports predictable machining and
finished-component quality.
-
Solid, cored and flat forms help control machining time and
material removal -
Published alloy chemistry and mechanical-property data support
material selection -
Standard and nonstandard lengths and sizes can be evaluated for
the job -
Cut length, machining allowance and certification needs can be
defined at quotation
Common alloy families
Compare strength, machinability and available stock forms.
Use the published values as a screening tool, then confirm the
exact form, condition, dimensions and governing specification
before release.

Mechanical values shown are Bunting catalog minimums for the stated
continuous-cast condition where published. Heat treatment, form and
specification can change requirements. Catalog properties are not a
substitute for the released material specification.
Build a complete request
Quote the finished part—not only the raw-bar diameter.
The strongest starting point is a print or a complete dimensional
and operating description. That lets stock form, machining
allowance and alloy be reviewed together.
- Finished outside and inside diameters
- Finished length and quantity
- Requested alloy and ASTM requirement
- Acceptable machining allowance
- Load, speed and lubrication method
- Shaft hardness and surface finish
- Temperature and environmental exposure
- Cut length and certification needs
