Continuous Cast Bronze Bar Stock and Castings
Magnolia supplies domestic continuous cast bronze in solid round bar, hollow tube, cut-to-length blanks, and finished machined parts. Our controlled continuous-casting process produces consistent bronze material for bearing, bushing, wear, machining, and other industrial applications.
Available alloys include CDA 936, AA Hard Bronze CDA 903, #120 High Lead Bronze, Magnolia B-1 Lead-Free Bronze, and other options based on the product form and application. Contact Magnolia with your alloy, dimensions, quantity, and machining requirements to confirm availability.
How the Continuous Casting Process Works
Molten bronze is fed through a furnace into a water-cooled graphite die. As the metal passes through the die it cools rapidly and is withdrawn in controlled increments using a precision roller system. This tight temperature control determines grain structure and metallurgical properties. Dirt, dross, and gases rise to the top of the melt and are left behind. The result is a bar, tube, or plate free of blowholes, porosity, shrinkage cavities, and inclusions that plague sand castings.
Common Ordering Options
Magnolia can supply continuous cast bronze in the product form that best fits your machining and production needs.
- Solid round bar for bushings, bearings, wear components, and machined parts
- Hollow tube for sleeve bearings, bushings, and applications where a pre-cored shape can reduce machining
- Cut-to-length blanks to reduce waste from excess material and scrap ends
- Semi-finished material with machining allowance for customers completing final machining in-house
- Finished machined parts for customers who need components supplied to drawing
When requesting a quote, provide the alloy, outside diameter, inside diameter if applicable, finished length, quantity, drawing or tolerances, and whether you need raw stock, a cut blank, semi-finished material, or completed machining.
Available Continuous Cast Bronze Alloys
- CDA 936 (Modified SAE 64) – Higher machinability, lower zinc content
- #120 High Lead – High lead bearing bronze for low-speed, high-load applications
- AA Hard Bronze (CDA 903) – Hard bronze for demanding wear applications
- B-1 Lead Free Bronze – Environmental compliance alternative with superior performance

Available Shapes and Sizes
Magnolia continuous cast bronze bar stock is available in solid round bar and hollow tube form, stocked in standard 105-inch lengths for immediate shipment. With over 300 sizes available, most orders ship from stock without lead time delays.
- Solid round bar — available through 12.5 inches O.D., suitable for machining into bushings, bearings, wear plates, and custom components
- Hollow tube — available in a range of wall thicknesses, reducing raw material and machining time for bushing and sleeve applications
- Cut-to-length blanks — Magnolia cuts blanks to your specified length, eliminating wasteful scrap ends and reducing your per-piece cost
- Finished machined parts — available up to 34 inches O.D. for orders requiring parts machined to your exact specifications
Custom profiles and non-standard sizes are available on request. Contact our team with your diameter, length, alloy, and quantity and we will confirm availability and lead time.
SAVE WITH MAGNOLIA CONTINUOUS CAST BRONZE!
1. Save ON MACHINING!
Magnolia Continuous-Cast Bronze can be finish machined at high speeds and feeds. A skin cut will finish machine Magnolia Continuous-Cast Bronze to nominal size. It is never necessary to finish machine a second time since Magnolia CDA 936 (Modified SAE 64) holds the finished dimensions to which it is machined. With it’s lower zinc content, CDA 936 machines 13% more freely than CDA 932 (SAE 660). This means longer tool life and less machine time in your shops.
2. Save WITH LESS WEIGHT
Magnolia Continuous-Cast Bronze finish machines to the size you order. It is never necessary to purchase “oversize” castings if you buy Magnolia Continuous-Cast Bronze. Purchase the exact diameters and lengths to which you want to finish machine. Let Magnolia cut your blanks, eliminating wasteful scrap ends.
3. Save BY RECYCLING
Magnolia will buy back scrap if kept separate and dry. Reduce your total cost by returning solids and clean turnings directly to the mill.
4. Save with special shapes
Continuous casting can provide material closer to the shape and dimensions required for your application. By reducing the amount of material that must be removed during machining, customers may be able to reduce scrap, machining time, and total material use.
Resolve your lead concerns the easy way with our B-1 Bronze. It’s the best alternative.
- Superior performance characteristics required in bearings ”
- Lower net cost than generic lead-free bronzes
- Addresses environmental and workplace concerns

Magnolia Guarantees No Rejects
Magnolia Bronzes are guaranteed to be free from all defects. In Magnolia Bronze there are no blow-holes, no sand spots, no segregated elements, no flaws… no under-surface faults of any kind to cause rejection.
Magnolia Bronzes are guaranteed to be free from all defects. Continuous Cast Bronze is produced in accordance with ASTM B505 and applicable industry specifications. QC certification is available upon request. In accordance with industry practice, guarantee is limited to free placement of material returned. But why just “hope” to get a good casting? Magnolia’s quality control procedure has resulted in returns of less than 1/2 of 1% of all bronze shipped over the last 10 years. This standard of excellence combined with our special alloy and our unique casting process assures you of the best possible value in bearing bronze.
