Jaw Crusher Spare Parts – Fixed & Swing Jaw Plates, OEM Compatible for Metso, Sandvik & Terex
Jaw crusher spare parts - primarily the fixed jaw plate and swing (movable) jaw plate - are the highest-wear components in any primary crushing circuit. A poor-quality jaw plate fails prematurely, drives up cost-per-tonne, and forces unplanned downtime. Duma manufactures jaw plates that are precision-cast to OEM dimensional tolerances, heat-treated under computer-controlled conditions, and verified by metallographic analysis before shipment - so they fit the first time and last.
Every plate leaves our 42,000 m² facility with a full quality dossier: hardness report, dimensional inspection record, heat-treatment curve, and metallographic certificate, all traceable to the production batch.
Material Options & When to Use Each
Selecting the right manganese grade is the single most important factor in jaw plate service life. Using a grade that is too low for your ore means rapid wear; a grade that is too stiff for a low-impact application will not work-harden effectively. Use the table below as your starting point - our engineers are happy to refine the recommendation once you share your ore data.
| Grade | Mn Content | Best For | Key Characteristic |
|---|---|---|---|
| Mn14 (Mn14Cr2) | 13–15% | Soft-to-medium ores (limestone, river gravel, recycled concrete); moderate impact | Good baseline toughness; most economical entry grade. Work-hardens to HB 450+ under steady impact. |
| Mn18 (Mn18Cr2) | 17–19% | Hard, abrasive ores (granite, basalt, iron ore, quartzite); high feed rates | Higher work-hardening ceiling; recommended for C100–C160 and heavy-duty primary stations. Balances toughness and wear resistance. |
| Mn22 (Mn22Cr2) | 20–23% | Extreme-abrasion applications: silica-rich ores, gold & copper primary crushing, very coarse feed | Maximum work-hardening potential (surface HB 500+). Specified for large-format plates where plate mass alone increases impact energy. |
| Alloy Upgrade (Mn18 + TiC) | 17–19% + TiC inserts | Ultra-abrasive silica, quartz; applications where standard Mn22 underperforms | Titanium carbide inserts embedded in the crushing face add a ceramic-hard wear layer, extending plate life by a further 30–60% in the right application. |
All Duma jaw plates undergo our controlled water-toughening (solution heat treatment) process - high-power circulation pumps ensure rapid, uniform quenching that produces a clean austenitic matrix with zero carbide precipitation. Every batch is verified against ASTM A128 / GB/T 13932.

Reference Weight & Dimension Ranges
Jaw plate dimensions are crusher-model-specific. The table below gives representative values by jaw crusher size class to help you estimate freight costs and lifting requirements before requesting a formal quotation.
| Crusher Class | Plate Width (mm) | Plate Height (mm) | Approx. Weight / plate |
|---|---|---|---|
| Small (e.g. C80, CJ211) | 500–700 | 400–600 | 80–200 kg |
| Medium (e.g. C100, C106, CJ411) | 700–1,000 | 600–900 | 200–500 kg |
| Large (e.g. C125, CJ615, CJ815) | 1,000–1,300 | 900–1,200 | 500–1,200 kg |
| Extra-Large (e.g. C160, C200) | 1,300–1,800 | 1,200–1,700 | 1,200–3,500 kg |
All weights are indicative for standard-tooth Mn18 plates. Weights vary ±15% depending on tooth profile (standard / quarry / super-grip) and material grade. Exact drawings and certified weights provided with order confirmation.

Jaw plates are one element of your crushing station's wear package. Consider sourcing cheek plates and side liners at the same time to consolidate freight and ensure consistent material grades across your wear package:
Quality Assurance – What Every Batch Includes
Duma operates a fully in-house production chain across 42,000 m² - raw material incoming inspection, sand casting, computer-controlled heat treatment (stepped heating + precision-temperature water toughening), CNC machining, and NDT. Because no step is outsourced, every batch is traceable.
Standard QC reports shipped with every order:
Hardness Report
Base hardness typically HB 200–230 post-quench; confirmed per batch. Expected work-hardening to HB 480–520+ under operating impact load.
Dimensional Inspection Record
Critical fit dimensions measured against OEM reference data; tolerances held to ±1–2 mm on seating faces.
Metallographic Certificate
High-magnification analysis confirming single-phase austenite matrix, zero carbide network, per ASTM A128 / GB/T 13932.
NDT Report (optional)
UT (ultrasonic) and MT (magnetic particle) non-destructive testing available on request for large plates or critical-duty applications.
