| Temper Designations for Copper Coils | ||||
| Temper Code | Description | Typical Hardness (HV) | Characteristics | |
| M / O | Soft / Annealed | ≤ 70 | Maximum ductility; lowest strength; excellent formability; suitable for deep drawing and complex forming | |
| Y4 / 1/4H | Quarter Hard | 55 – 100 | Light cold working; balance of strength and ductility; good formability | |
| Y2 / 1/2H | Half Hard | 75 – 120 | Moderate cold working; increased strength; good electrical properties | |
| Y / H | Hard | 80 – 120 | Significant cold working; high strength; good spring properties; limited formability | |
| T / EH / HH | Extra Hard | ≥ 110 | Maximum cold working; highest strength; minimal ductility | |
