In aggregate production, jaw crusher wear parts have a direct impact on equipment performance, maintenance requirements, and overall uptime. Choosing the right jaw die profile for the application can help producers maintain efficient crushing while getting more useful life from their wear parts.
Metso Coarse Corrugated Jaw Dies are designed for Metso Nordberg C Series jaw crushers and combine a specialized tooth profile with Metso’s XT715 manganese alloy. For operations looking to extend jaw die wear life while maintaining strong crushing performance, the Coarse Corrugated profile offers an option worth considering.
What Are Metso Coarse Corrugated Jaw Dies?
The jaw dies inside a jaw crusher do more than protect the machine from wear. Their profile affects how material moves through the crushing chamber, how effectively the crusher grips the feed, and how the material breaks during crushing.
Metso’s Coarse Corrugated jaw profile incorporates fewer, wider teeth and large valleys between them. The additional open space between the teeth helps fines move through the crushing chamber rather than becoming unnecessarily packed within it.
The rounded tooth geometry also provides more grip than a traditional flat-tooth profile. This combination makes the Coarse Corrugated design particularly useful in applications where fines, slippery feed material, or slabby material can create production challenges.
Increase Jaw Die Wear Life with XT715 Alloy
One of the primary advantages of Metso Coarse Corrugated Jaw Dies is extended wear life.
Metso manufactures these jaw dies using XT715, a high-manganese alloy developed specifically for jaw crusher applications. When combined with the redesigned Coarse Corrugated profile, Metso reports up to 50% higher wear life compared with traditional jaw dies, depending on the application and operating conditions.
Longer jaw die life can reduce the frequency of wear-part replacements and help producers get more production between planned maintenance events.
Reduce Crusher Maintenance and Downtime
Replacing jaw crusher wear parts requires more than the cost of the parts themselves. A jaw die changeout requires planned downtime, maintenance labor, lifting equipment, and time that could otherwise be spent producing material.
Extending wear life can help reduce the number of jaw die changeouts required over time. For an aggregate operation, fewer changeouts can contribute to:
- Increased crusher availability and production time
- Reduced maintenance frequency
- Lower labor associated with wear-part replacement
- Fewer planned production interruptions
- Reduced need for lifting equipment during changeouts
- Less employee exposure to wear-part replacement activities
While wear cannot be eliminated from a crushing operation, selecting wear parts suited to the application can help operators manage it more effectively.
Improve Material Flow Through the Jaw Crusher
Wear life is only part of the benefit of choosing the correct jaw die profile.
Fine material entering a jaw crusher can contribute to packing within the crushing chamber, particularly when operating at tighter closed-side settings. Metso designed the Coarse Corrugated profile with wide valleys between the teeth, providing additional space for fines to pass through the chamber.
The profile can also help when feed material tends to produce elongated or slabby pieces. Its tooth geometry helps grip and break material rather than relying on a flatter crushing surface.
According to Metso, the Coarse Corrugated profile can improve capacity and product shape, particularly with slippery feed material. Actual performance will depend on the crusher, feed characteristics, settings, operating conditions, and overall crushing circuit.
Why the Right Jaw Crusher Wear Profile Matters
There is no single jaw die profile that is ideal for every crushing application.
Feed material can vary significantly in abrasiveness, crushability, moisture content, fines content, and particle shape. Crusher settings and production requirements also influence which wear profile will perform best.
Selecting a jaw die based solely on initial cost can overlook the effect that wear parts have on the entire crushing process. The right jaw crusher wear parts can help maintain the intended chamber geometry, support efficient material flow, and reduce production losses associated with excessive or uneven wear.
For producers experiencing frequent jaw die changes, packing, poor material grip, or excessive slabby material, evaluating the current jaw profile may identify an opportunity to improve performance.
Designed for Metso Nordberg C Series Jaw Crushers
Metso Coarse Corrugated Jaw Dies are designed for Nordberg C Series jaw crushers. Because the fixed and movable jaw profiles are engineered to work together, the Coarse Corrugated jaws should be installed as a matched set rather than mixed with a different jaw profile.
Proper wear-part selection should also account for the specific crusher model and application. Monitoring jaw wear throughout its service life remains important, as abnormal wear patterns may indicate that the jaw dies need to be changed earlier or that operating conditions should be evaluated.

Reducing crusher downtime does not always require changing the entire crushing process. In some applications, selecting a jaw die profile better suited to the feed material and operating conditions can provide meaningful improvements in wear life and crusher performance.
Metso Coarse Corrugated Jaw Dies combine a wear-focused profile with XT715 manganese alloy to help extend service life, improve material handling through the crushing chamber, and reduce the frequency of wear-part changeouts.
