Cast Bronze Cored Bar Stock

Q: Is SAE 660 the same as C93200?

Yes. C93200 (UNS) and SAE 660 are the same alloy (High-Leaded Tin Bronze). You may also see it listed as CDA 932 or "Bearing Bronze." These terms are interchangeable.

Q: Is the bar stock sold oversized?

Yes. Cast bronze bar stock is sold oversized on OD (and undersized on ID for cored bar) to allow for finish machining to your final dimensions.

Q: How is the machinability of C93200?

Excellent. C93200 has a machinability rating of 100 (the baseline for free-machining bronze). It produces short, broken chips and machines easily with standard tooling.

Q: What is the maximum operating temperature?

The alloy itself can handle temperatures up to 450°F. However, the practical limit is often determined by the lubricant—most petroleum-based oils break down well before the bronze fails.

Continuous cast per ASTM B505. C93200, C95400, and C86300.

Over 75 dimensions from 1/2" to 11" ID, with OD from 1" to 12", in three alloys: C93200 (SAE 660) for general bearing use, C95400 (aluminum bronze) for high-strength applications, and C86300 (manganese bronze) for heavy-load and impact resistance.

Frequently Asked Questions

Expert answers to common technical questions about cast bronze cored bar stock.

Is SAE 660 the same as C93200?

When should I choose C93200 vs C95400?

Choose C93200 for general-purpose bearing applications with moderate loads (max 4,000 PSI) and speeds (max 750 SFM). It is cost-effective and has excellent anti-friction properties. Upgrade to C95400 only if you require high tensile strength, impact resistance, or corrosion resistance.
