Hardox vs CCO Wear Plate: Which Wear Plate Performs Better?
Introduction
In mining, cement, and bulk material handling industries, equipment is constantly exposed to severe abrasion, impact, and erosion.
To protect equipment and extend service life, two widely used materials are:
- Hardox wear plate
- Chromium Carbide Overlay (CCO) wear plate
Understanding their differences is essential for selecting the right solution for your application.

What Is Hardox Wear Plate?
Hardox is a brand of wear-resistant steel produced for high strength and impact resistance applications.
It features:
- High hardness (e.g., Hardox 400 / 450 / 500 grades)
- Uniform material structure
- Excellent toughness under impact
- Good weldability and formability
Hardox is widely used in:
- Dump truck bodies
- Excavator buckets
- Structural wear parts
- Construction machinery
What Is CCO Wear Plate?
Chromium Carbide Overlay (CCO) wear plate is a composite wear-resistant material made by welding a high-chromium carbide layer onto a steel base plate.
Its structure includes:
- Extremely hard overlay layer (high chromium carbides)
- Tough steel backing plate for structural strength
CCO wear plate is designed for extreme abrasion environments such as continuous material sliding.

Hardox vs CCO Wear Plate: Key Differences
1. Wear Resistance
- CCO wear plate: Extremely high abrasion resistance
- Hardox: Balanced wear + impact resistance
2. Impact Resistance
- CCO: Lower resistance to heavy impact
- Hardox: Excellent impact toughness
3. Structure
- CCO: Composite (overlay + base steel)
- Hardox: Homogeneous alloy steel
4. Best Application
- CCO wear plate: Mining chutes, hoppers, conveyors
- Hardox: Excavator buckets, dump trucks, structural parts
How to Choose Between Hardox and CCO
Choose CCO wear plate if:
- Severe abrasion is the main issue
- Material flows continuously (sliding wear)
- Long service life is required
Choose Hardox if:
- High impact loads exist
- Structural strength is important
- Bending and fabrication are required
Applications in Industry
Wear plates are widely used in:
- Mining industry (ore handling systems)
- Cement plants (clinker and coal systems)
- Steel plants
- Bulk material transport systems

Cost vs Service Life
Although Hardox is easier to fabricate and handles impact well, CCO wear plate provides:
- Longer wear life in abrasion conditions
- Lower replacement frequency
- Reduced downtime cost
In long-term mining operations, CCO often delivers better cost efficiency.
FAQ
Is CCO better than Hardox?
It depends on the application. CCO is better for abrasion, Hardox is better for impact.
What is the main difference between Hardox and CCO?
Hardox is a solid steel plate, while CCO is a composite overlay wear plate.
Which lasts longer?
In abrasive environments, CCO wear plates typically last longer.
Conclusion
Hardox and CCO wear plates serve different engineering needs:
- Hardox → impact and structural applications
- CCO → extreme abrasion environments
For mining and cement industries with severe wear conditions, CCO wear plate is often the more durable and cost-effective solution.
