Jaw crusher wear parts are essential components in mining, quarrying, and aggregate production, directly influencing crushing efficiency, equipment stability, and long-term operating costs. As a professional manufacturer of crushing and mining spare parts, Jiangxi Duma Machinery provides high-performance jaw plates and related wear components engineered for long service life and demanding working conditions.
This guide explains the materials used in jaw crusher wear parts, how to choose the right jaw plate, and why high-quality parts matter for your crushing operations.

1. Common Materials Used in Jaw Crusher Wear Parts
Different applications require different alloy compositions. Below are the most widely used materials in jaw crusher wear parts:
-
Mn14 – Standard High-Manganese Steel
·Excellent toughness and ductility
·Suitable for soft to medium-hard materials
·Ideal for non-abrasive or low-impact applications
·A cost-effective option for general-purpose crushing
-
Mn18 – Enhanced High-Manganese Steel
The most commonly used material in mining
Strong work-hardening properties
Ideal for granite, basalt, quartz, river gravel, and hard ores
Provides a balanced combination of toughness and wear resistance
-
Mn22 – Super High-Manganese Steel
·Designed for extremely abrasive working conditions
·Best suited for gold mines, iron ore plants, and hard-rock quarries
·Provides maximum resistance to severe impact and friction

-
TIC Inserts / Alloy Steel Composite Jaw Plates
·Titanium-carbide reinforced inserts
·2–4× longer wear life than standard manganese
·Excellent for high-impact feeders, recycled concrete, and extreme abrasion
·Reduces downtime and significantly lowers cost per ton
As a leading jaw crusher wear parts manufacturer, Duma Machinery can produce customized materials, thicknesses, tooth profiles, and surface designs for different crusher models.

2. How to Choose the Right Jaw Plate Material
Selecting the correct material ensures maximum productivity and minimal downtime:
| Application Condition | Recommended Material |
|---|---|
| Soft limestone, low-abrasion rocks | Mn14 |
| General mining, most quarry materials | Mn18 |
| Extremely hard or highly abrasive stones | Mn22 |
| High-impact or ultra-abrasive operations | TIC Inserts |
Professional Tip:
Jaw plates should match the feed size, rock abrasiveness, crusher speed, and chamber profile. At Jiangxi Duma Machinery, our engineers evaluate these parameters and provide tailored recommendations for better crushing performance.


3. Why High-Quality Jaw Crusher Wear Parts Matter
Using high-quality wear parts provides long-term benefits for crushing operations:


-
Enhanced Equipment Stability
Precision-engineered jaw plates ensure proper fit and reduce vibration, improving overall crusher stability.
-
Reduced Downtime
High-resistance materials prolong service life and minimize maintenance frequency.
-
Lower Cost per Ton
Longer wear life and stable crushing efficiency reduce the total cost of ownership.
-
Consistent Output Quality
Premium jaw plates maintain uniform product size, essential for downstream operations.
-
Improved Operational Safety
Reliable materials reduce the risk of sudden failures or unplanned shutdowns.
As a specialized manufacturer of crushing and mining spare parts, Jiangxi Duma Machinery provides certified, performance-tested jaw plates manufactured using advanced casting, heat treatment, and quality inspection processes.
4. Types of Jaw Plate Tooth Profiles (With Applications)
Tooth design also affects wear life and crushing efficiency:
-
Standard Tooth
General-purpose
Suitable for soft to medium-hard materials
-
Super Grizzly Tooth
Strong penetration ability
Ideal for hard, blocky stones
-
Corrugated Tooth
Improved grip and material retention
Best for recycling applications
-
Flat & Non-Tooth Design
Uses compressive force
Suitable for highly abrasive feed
Duma offers all standard and special tooth profiles, including custom designs.
