high-copper brass alloy (also classified as "red brass") with a primary composition of copper (Cu) and zinc (Zn), along with trace elements. The exact chemical limits are standardized under ASTM specifications such as ASTM B36/B36M and ASTM B587. Here is the detailed composition:

| Element | Content Range (wt%) | Notes |
| Copper (Cu) | 94.0–96.0% | Primary constituent |
| Zinc (Zn) | Balance | Typically 4–6% (residual) |
| Lead (Pb) | ≤0.05% | Strictly controlled impurity |
| Iron (Fe) | ≤0.05% | Impurity limit per ASTM B36 |
| Other Impurities | ≤0.3% (total) | Includes P, Sb, Bi, etc. [1](#user-content-ref-4), [3](#user-content-ref-6), [18](#user-content-ref-12), [31](#user-content-ref-22) |
