Tin/Lead Bronzes (e.g., C83600, C93200): Excellent machinability and embeddability for general bearings.
- Aluminum Bronzes (e.g., C95200, C95500): High strength and corrosion resistance for marine/offshore use.
- High-Tensile Brasses (e.g., C86200): For heavy-duty, high-load applications.
- Self-Lubricating Enhancements: Graphite plugs, PTFE impregnation, or solid lubricants for oil-free operation.
The chemical compositions below are based on the nominal or specified ranges from ASTM B505 (continuous-cast copper alloys). These are weight percentages (wt%). Copper (Cu) is the balance for all alloys (i.e., Cu = 100% – sum of other elements). Ranges are provided where specified; single values are nominal. Data is sourced from standard references, including ASTM specifications and manufacturer data sheets for consistency. Minor elements (e.g., P, Sb) are included if specified; “max” indicates upper limits.

Notes
- Dashes (-): Element not intentionally added or specified (typically <0.05% or negligible).
- Max values: Upper limits; actual content is usually lower.
- Other Elements: Includes phosphorus (P, often for deoxidation), nickel (Ni, sometimes includes cobalt), silicon (Si), etc. Residual elements (e.g., As, Sb, S) are generally <0.05% total.
- Sources: Derived from ASTM B505/B505M-23 specifications, cross-referenced with CDA (Copper Development Association) data and manufacturer sheets. For precise applications, consult the latest ASTM standard.
- Alloy Families Recap: Tin bronzes (e.g., C83600–C94100) emphasize Sn for strength; high tensile brasses (C86200, C86300) use Zn/Mn/Al; aluminum bronzes (C95200+) use Al for corrosion resistance.

Finished products, solution for the manufacture of finished bronze parts and self lubricating bronze based on our clients’ drawings.
We specialize in providing end-to-end solutions, from material selection (using alloys like those in the ASTM B271 table, such as C93200 for bearings or C95400 for high-strength parts) to precision fabrication. Our process ensures parts meet exact specifications, tolerances, and performance needs, reducing friction, wear, and downtime.
