H75 brass (CuZn25, CW503L, 2.0265, C26000, Л75, or C2600) is the mid-zinc alloy we like for jobs needing good cold formability and that rich golden color. With 25% zinc, it’s more ductile than higher-zinc grades, making it excellent for deep drawing strips, tubes, and decorative parts—strong enough for light structural use but soft enough to form without cracking. The color is a deep gold, perfect for visible applications.
At Cymber Metal, H75 is popular for customers wanting decorative strips and drawn tubes that look premium. This guide shares what we’ve seen in the shop: properties, processes, common issues, and tips to get beautiful, formable parts.
H75 Brass Equivalent Grades and Properties Overview
| Designation | Standard | Zinc Content | Key Strengths | Best Forms | Machinability/Formability | Relative Cost |
|---|---|---|---|---|---|---|
| H75 | Chinese (GB) | 25% | Excellent deep drawing, rich golden color | Strips, tubes, decorative | Excellent cold work | Low |
| CuZn25 | European | 25% | High ductility, good corrosion | Drawn tubes, strips | Excellent | Low |
| CW503L | EN | 25% | Consistent for forming | Decorative parts | Excellent | Low |
| C26000 | ASTM | 24–27% | Cartridge brass, formable | Tubes, decorative | Good | Low |
| 2.0265 | DIN | 25% | High surface quality | Precision drawn products | Excellent | Low |
Quick Tip: H75 for deep drawn decorative strips and tubes—25% zinc gives the perfect mix of formability and that deep gold shine.
Suitable Processes for H75 Brass
H75 shines in cold working:
- Cold Rolling & Drawing → Core for strips and tubes.
- Deep Drawing → For decorative caps and shells.
- CNC Turning → Light cuts for features on rods.
- Stamping → Flat decorative parts.
- Polishing → Brings out the deep golden finish.
Advantages of H75 Brass
- Excellent cold formability → Deep draws and bends without cracking.
- Rich golden color → Deeper tone than higher-zinc brasses.
- Good corrosion resistance → Fine for indoor decorative use.
- Balanced strength → Better than low-zinc for light loads.
- Easy polishing → Mirror-like shine quickly.
-
Challenges & Practical Solutions
H75 is ductile but soft:
- Cracking in deep draws → Anneal between stages.
- Surface marking → Soft material scratches—handle carefully.
- Thickness control → Precision rolling needed for thin strips.
Engineering Experience: In our H75 projects at Cymber Metal, deep drawing decorative caps for lighting fixtures sometimes cracked on tight radii. We solved it with better lubricant and intermediate annealing, consistently getting smooth draws and that rich golden finish customers expect.
Pro Tip: Use protective film on strips during rolling—keeps the surface perfect for polishing later.

Design Considerations & Tips
- Thickness: 0.2–2 mm for strips and light tubes.
- Tolerances: ±0.02 mm in drawing.
- Radii: At least 2x thickness for safe draws.
- Finishing: Polish or lacquer to protect the gold color.
Tooling & Parameter Recommendations
- Drawing Dies: Polished for smooth flow.
- Example Parameters (Turning H75 rods):
- Spindle: 2,500–4,500 RPM
- Feed: 0.1–0.25 mm/rev
- Light passes for finish
- Lubricant: Heavy for deep draws.
