Jaw Plates for Metso C-Series & Sandvik CJ – OEM-Compatible | Factory Direct – Duma
Jaw Plate For Crusher: Duma jaw plates are direct-cast, heat-treated, and inspected in our own 42,000 m² foundry. Designed as OEM-compatible replacements for Metso, Sandvik, Terex and other major brands - with a verified 20–40% service life advantage over standard market grades.
Material Options: Mn14 / Mn18 / Mn22 / High Chrome – Which Grade Is Right for You?
Selecting the correct alloy grade is critical to maximizing service life. Below is Duma's standard material lineup and the scenarios each grade suits best:
| Grade | Mn Content | Best For | Typical Work-Hardening |
|---|---|---|---|
| Mn14 (ZGMn13) | ~13–14% | Soft to medium rock; recycled concrete/asphalt; low-impact feeds where cost control matters | Surface HB 200 → HB 400+ |
| Mn18 | ~18% | General mining & quarrying: granite, basalt, river gravel, limestone with medium abrasiveness | Surface HB 200 → HB 450+ |
| Mn22 | ~22% | Hard rock & high-impact conditions: iron ore, quartz, diabase; large feed sizes in primary crushing | Surface HB 200 → HB 500+ |
| High Chrome Iron (Cr26+) | N/A | Extremely abrasive, low-impact feeds where abrasion dominates over impact; silica sand, dry limestone | High initial hardness, limited work-hardening |
| TIC Insert Composite | Mn18 base + TiC | Maximum service life in the most abrasive conditions; copper ore, gold ore, highly siliceous rock | Exceptional wear resistance at contact surface |
Not sure which grade fits your ore? Send us your rock type and crusher model - our engineers will recommend the optimal alloy free of charge.
Why Duma Jaw Plates Last 20–40% Longer
The service life advantage comes from two proprietary process controls that most competitors skip:
Step-Heating Heat Treatment
Rather than a single-ramp furnace cycle, Duma uses computer-controlled staged temperature increases before the final solution treatment. This eliminates residual casting stress and ensures uniform carbide dissolution throughout the cross-section.
Forced-Circulation Water Quenching (Water Toughening)
High-power circulation pumps maintain water temperature below 30 °C during quenching, locking in a 100% pure austenitic microstructure. The result: maximum work-hardening potential under impact - initial HB ≈ 200, escalating to HB 500+ in service.
Metallographic Verification on Every Batch
Our in-house lab uses high-magnification metallographic microscopy and image analysis software to confirm zero reticular carbide precipitation - the root cause of premature brittle fractures in inferior plates. Compliant with ASTM A128 / GB/T 13932.
Non-Destructive Testing (NDT)
Every plate undergoes PT (Penetrant Testing) for surface cracks and UT (Ultrasonic Testing) for internal voids. MT (Magnetic Particle) and PT reports are included with each shipment at no extra charge.
Compatible Crusher Models – 4,000+ Patterns in Stock
Duma maintains over 4,000 precision casting patterns covering the world's major jaw crusher brands. Most standard models ship from existing patterns - no new tooling costs, no delays.

Weight & Dimension Reference
Jaw plate dimensions vary significantly by crusher size and model. The table below provides representative reference values for common series:
| Crusher Model | Jaw Opening (mm) | Fixed Plate Weight (kg) | Swing Plate Weight (kg) | Set Weight (approx.) |
|---|---|---|---|---|
| Metso C80 | 800 × 510 | ~185 | ~170 | ~355 kg |
| Metso C100 | 1,000 × 760 | ~310 | ~280 | ~590 kg |
| Metso C125 | 1,250 × 950 | ~560 | ~510 | ~1,070 kg |
| Metso C160 | 1,600 × 1,200 | ~1,100 | ~980 | ~2,080 kg |
| Sandvik CJ412 | 1,100 × 700 | ~340 | ~310 | ~650 kg |
| Sandvik CJ615 | 1,500 × 1,100 | ~820 | ~760 | ~1,580 kg |
All weights are approximate reference values based on standard Mn18 grade. Actual weight varies with tooth profile (Standard / Corrugated / Heavy-Duty) and alloy selection. Contact us for exact drawings and confirmed weights for your model.
Duma's "Zero-Defect" Quality Barrier
Every jaw plate undergoes a rigorous multi-stage inspection process in our in-house lab:
PT (Penetrant Testing)
Mandatory surface crack detection to guarantee a flawless "perfect skin" before the plate confronts high-impact stress.
UT (Ultrasonic Testing)
Internal defect scanning to completely eliminate subsurface gas holes or slag inclusions.
Metallographic Analysis
Verification of a 100% pure austenitic structure to unleash its maximum work-hardening potential.
Hardness Testing
Guaranteed initial hardness of HB200, engineered to escalate to HB500+ during in-service operation.

Frequently Asked Questions
What jaw plate material should I choose for granite crushing?
Mn18 is the standard choice for granite and basalt. For very hard, high-silica granite (above 250 MPa compressive strength) or large primary feed, upgrade to Mn22 or TIC Insert for maximum life.
Can Duma produce plates from my worn sample (reverse engineering)?
Yes. Send us the worn plate or accurate dimensional drawings and our engineering team will develop a new pattern. Most reverse-engineered patterns are ready within the standard 35–45 day lead time.
Do you supply both the fixed jaw plate and the swing jaw plate?
Yes, we supply complete matched sets (fixed + swing) as well as individual pieces. We also supply jaw wedges, cheek plates, bolts, and nuts as part of a one-stop rebuild kit.
What is the warranty?
12 months from delivery against casting defects. Our 24/7 technical support team is available to assist with any quality concern.
