H85 brass (known as CuZn15, CW502L, 2.0240, C23000, Л85, or C2300) is the low-zinc alloy we reach for when we need that rich golden shine and excellent cold workability. With only 15% zinc, it’s softer and more ductile than higher-zinc brasses, making it perfect for rolling into strips and rods rather than extrusion tubes. It’s not suited for heavy deep drawing into pipes—that’s where higher-zinc grades shine—but for strips, rods, and decorative parts, nothing beats its beautiful color and polish.
At Cymber Metal, we’ve been working with H85 a lot lately for customers who want that classic gold look in architectural trim and hardware. This guide shares what we’ve seen in the shop: properties, processes, common issues, and tips to get flawless strips, rods, and decorative pieces.
H85 Brass Equivalent Grades and Properties Overview
| Designation | Standard | Zinc Content | Key Strengths | Best Forms | Machinability/Formability | Relative Cost |
|---|---|---|---|---|---|---|
| H85 | Chinese (GB) | 15% | Rich golden color, excellent cold rolling | Strips, rods, decorative | Excellent cold work | Low |
| CuZn15 | European | 15% | Beautiful luster, good ductility | Strips, rods | Excellent | Low |
| CW502L | EN | 15% | Consistent properties, polishability | Decorative parts | Excellent | Low |
| C23000 | ASTM | 15% | Red brass aesthetic, corrosion resistance | Strips, rods | Good | Low |
| 2.0240 | DIN | 15% | High surface quality | Precision rolled products | Excellent | Low |
Quick Tip: H85 isn’t for extruded tubes—its low zinc makes it ideal for rolling thin strips and rods with that eye-catching gold shine.
Suitable Processes for H85 Brass
H85 excels in cold working rather than hot extrusion:
- Cold Rolling → Perfect for thin strips and foil.
- Extrusion & Drawing → For solid rods and bars.
- CNC Turning/Milling → Light cuts for decorative features.
- Polishing & Buffing → Brings out that brilliant golden finish.
- Stamping → For flat decorative parts.
Advantages of H85 Brass
- Stunning golden appearance → Polishes to a mirror-like shine that lasts.
- Excellent cold formability → Rolls easily into strips and rods without cracking.
- Good corrosion resistance → Suitable for indoor decorative use.
- Cost-effective → Low zinc keeps material affordable.
- Easy finishing → Takes plating or lacquer beautifully.
-
Challenges & Practical Solutions
H85 is soft, so handling requires care:
- Surface scratching → Soft material marks easily during rolling.
- Thickness variation → In rolling thin strips.
- Limited for tubes → Not suitable for extrusion—stick to strips and rods.
Engineering Experience: In our H85 projects at Cymber Metal, rolling thin decorative strips for luxury hardware was challenging with surface marks. We solved it by using protective films during rolling and careful handling, consistently delivering that flawless golden shine customers love without scratches or defects.
Pro Tip: Always protect surfaces during transport—H85′s beauty is in that perfect gold finish.

Design Considerations & Tips
- Thickness: 0.1–3 mm for strips; ideal for decorative rolling.
- Tolerances: ±0.01–0.05 mm in rolling.
- Surface Protection: Lacquer or film for long-term shine.
- Finishing: Polish early to enhance gold appearance.
Tooling & Parameter Recommendations
- Rolling Mills: Precision for uniform strips.
- Example Parameters (Turning H85 rods):
- Spindle: 2,000–4,000 RPM
- Feed: 0.05–0.2 mm/rev
- Light passes for finish
- Lubricant: Essential in rolling to prevent marks.
