In high-intensity working conditions such as mine crushing, open-pit mining and aggregate processing, traditional high-manganese steel and high-chromium cast iron wear parts always suffer from rapid abrasion, frequent replacement and high equipment downtime costs. As a new type of composite wear-resistant component, titanium carbide (TiC) insertwear parts effectively solve the common defects of traditional parts including insufficient wear resistance, cracking and falling off. With professional powder proportioning, mature pre-insert casting technology and high hardness stability, these parts can extend the service life by 2 to 3 times, widely used in wear parts for global mining projects.
The excellent performance of TiC insert wear parts comes from scientific alloy powder ratio, which balances hardness, toughness, impact resistance and structural stability. The precise material composition is shown below:
Titanium Carbide Powder: 48%–Core wear-resistant material with ultra-high hardness, outstanding abrasion resistance and high-temperature resistance. It resists strong ore impact and material scouring, greatly reducing surface wear of components.
Iron Powder: 38%–Basic bonding matrix that improves alloy fusion and molding compactness. It eliminates internal pores and structural looseness, ensuring overall structural uniformity and reliability.
Manganese Iron Powder: 10%–Matches the performance of high manganese steel substrate, significantly enhances overall toughness and impact resistance, and prevents cracking or chipping under heavy mining impact loads.
Nickel Powder, Molybdenum Powder and Other Rare Metal Powders: 4% –Reinforced modified elements that refine the internal alloy structure, improve bonding strength, thermal stability and corrosion resistance, adapting to complex and harsh global mining working conditions.
Our titanium carbide bars adopt pre-insert one-piece casting technology. All core parameters are strictly controlled to avoid cracking, displacement and uneven distribution, ensuring stable and consistent product quality.
Before pouring, standard titanium carbide wear bars are fixed and arranged in the sand box in advance to ensure accurate positioning and firm fixation, preventing deviation during high-temperature casting.
Fixed rod diameter: 20mm
Standard rod spacing: 15mm–20mm
This 15–20mm spacing is the most mature and stable process parameter in actual production. If the TiC bars are arranged too densely, stress concentration will occur during casting and impact operation, easily causing cracking. If the spacing is too wide, the overall wear resistance will be insufficient. The scientific spacing perfectly balances wear resistance and structural toughness.
After high-temperature pouring, natural cooling and precise heat treatment, the finished product reaches a stable hardness of HRC60, combining ultra-high surface hardness and strong matrix toughness, avoiding the “hard but brittle” defect of single-material wear parts.
Different from ordinary welded or inlaid wear parts, our TiC insert parts take high manganese steel as the base body. Under continuous strong impact in mining operation, the high manganese steel matrix will produce micro shrinkage and automatically lock the internal titanium carbide barstightly. The stronger the impact force, the tighter the combination. This unique physical self-tightening effect completely solves the long-standing problem of loose and falling-off wear blocks in traditional products.
With HRC60 ultra-high hardness and excellent TiC wear resistance, coupled with optimized alloy formula, the comprehensive anti-scouring and anti-impact performance is far better than traditional high manganese steel and high chromium parts. Under the same mining working conditions,the service life is increased by 200%–300%, effectively reducing replacement frequency, lowering equipment shutdown time and minimizing mine operation and maintenance costs.
Anti-cracking & High Toughness, Suitable for All Mining Conditions
Benefiting from the reasonable 15–20mm rod spacing and rare metal modification formula, the product achieves perfect coordination of hardness and toughness. It does not crack or break under heavy impact, and adapts to various harsh environments including open-pit mines, aggregate crushing, construction waste recycling and low-temperature mining areas. It is widely applicable for crusher liners, hammer blow bars, excavator bucket teeth, hydraulic shovel wear plates and other mining wear components.
One-piece sand box pre-insert casting makes the TiC bars and steel matrix metallurgically fused without layering, gaps or weak bonding points. Compared with post-welding and spray coating processes, the integrated structure will not lose the wear-resistant layer in advance, maintaining long-term stable wear resistance.
We provide professional mining wear analysis and customized TiC insertservice for all customers. By analyzing on-site photos of used old wear parts, our technical team can accurately identify the severely worn key areas and weak stress points of crusher liners, blow bars, bucket teeth and hydraulic shovel wear plates.
Different from uniform blind insert on the whole surface, our targeted inlay scheme only arranges titanium carbide bars at high-abrasion key positions. This scientific customization avoids unnecessary material waste caused by full-area insert, effectively controls production costs, and eliminates customer’s capital waste on redundant wear-resistant structures. It realizes precision wear resistance, cost optimization and maximum cost-performance ratio for different mining working conditions and equipment wear characteristics.

Titanium carbide insert wear parts are perfectly suitable for jaw crushers, cone crushers, impact crushers, metal recycling crushers, large electric shovels and hydraulic shovels. They adapt to high-load mining conditions in Australia, Europe, South America, Russia and North America. As a cost-effective upgrade solution for original brand wear parts, they have become the preferred choice for global mines to reduce costs and improve working efficiency.
