Plaque CCO: Common Thickness and Size Specifications of Chromium Carbide Overlay Plate
Plaque CCO (Plaque de superposition de carbure de chrome) is a bimetallic wear-resistant steel plate composed of a mild steel base and a hard chromium carbide overlay layer. Its performance is defined not only by material composition but also by its base plate thickness, épaisseur de recouvrement, et total plate size.
Different thickness combinations are designed to meet various wear conditions, from light abrasion to extreme heavy-duty mining applications.
1. Common CCO Plate Thickness Structures
CCO plates are usually expressed in the format: base plate thickness + overlay layer thickness.
| Spécification | Total Thickness | Wear Condition |
|---|---|---|
| 4+3 mm | 7 mm | Light abrasion |
| 6+4 mm | 10 mm | General industrial wear |
| 6+6 mm | 12 mm | Medium abrasion |
| 8+4 mm | 12 mm | Impact + abrasion |
| 8+6 mm | 14 mm | Heavy-duty wear systems |
| 10+6 mm | 16 mm | Mining and cement industry |
| 12+8 mm | 20 mm | Extreme abrasion conditions |
2. Common Overlay Thickness Range
| Épaisseur de superposition | Niveau de résistance à l'usure |
|---|---|
| 3–4 mm | Standard wear protection |
| 5–6mm | Haute résistance à l'usure |
| 7–8mm | Severe abrasion conditions |
| 10 mm+ | Environnements d'usure extrêmes |
3. Common Plate Size (Largeur & Longueur)
In addition to thickness, CCO plates are also supplied in standard sheet sizes:
| Article | Common Range |
|---|---|
| Largeur | 1000 mm – 3000 mm |
| Longueur | 2000 mm – 6000 mm |
| Cut-to-size | Available based on customer requirements |
4. Standard Plate Formats
- Flat plates: Used for liners and structural wear protection
- Cut pieces: Custom shapes for chutes, trémies, and ducts
- Fabricated parts: Welded wear assemblies
5. How Thickness Affects Performance
- Thicker base plate: Better structural strength and impact resistance
- Thicker overlay: Longer wear life in abrasive conditions
- Balanced design: Optimized for both wear and service life
6. Application Matching by Thickness
| Application | Recommended Specification |
|---|---|
| Light conveyor systems | 4+3 mm / 6+4 mm |
| Équipement minier général | 6+6 mm / 8+4 mm |
| Cement plant chutes | 8+6 mm / 10+6 mm |
| Heavy mining & concasseurs | 12+8 mm |
