Cemented Carbide Plates

FOTMA cemented carbide plates, with “top-tier hardness + extreme wear resistance” at their core, are engineered for harsh industrial environments! Whether facing intense impacts in mining machinery or high-temperature corrosion in chemical equipment, our plates serve as “steel armor” for equipment, significantly extending service life, saving downtime, maintenance, and costs!

Core Performance: Hardcore Material, Fearless Challenges

1. Dual Assurance of Hardness and Wear Resistance
   • Hardness Surpasses Steel: Tungsten carbide (YG series) plates achieve a hardness of HRA ≥ 89 (equivalent to HRC 75), with tungsten carbide content up to 70%-97%. Wear resistance is 150x higher than high-strength manganese steel.
   • Adjustable Cobalt Content:
     Low-Cobalt Formula (6%-8%): Designed for high-wear, low-impact scenarios (e.g., sand conveyor liners, nozzles).
     High-Cobalt Formula (10%-15%): Enhanced toughness for high-impact applications like mining crusher hammers and jaw plates.
2. Stability in Extreme Environments
   • Corrosion Resistance: Outperforms stainless steel in acid/alkali/salt environments. Dedicated models for chemical equipment and marine engineering.
   • High-Temperature Red Hardness: Maintains over 8% effective hardness retention at 600°C, ideal for hot roller bed liners and furnace guides.
   • Anti-Adhesion Properties: Mirror finish (Ra ≤ 0.2µm) prevents material adhesion in food machinery and plastic molds.
3. Flexible Structural Design
   • Complete Size Range: Standard thickness 10-50mm (customizable up to 100mm), dimensions up to 1200×600mm.
   • Composite Upgrades: Optional embedded plates (carbide + steel backing) or gradient transition layers to reduce installation costs and weight.

Frequently Asked Questions

Q1: What are cemented carbide plates used for?

A1: Cemented carbide plates are widely used in stamping tools, wear-resistant parts, crushing equipment, and high-impact mining tools. Their exceptional hardness and strength make them ideal for demanding industrial applications.

Q2: What grades of tungsten carbide are available for these plates?

A2: Available grades include YG6A, YG8, YG11, YG15C, and YG20X. Each grade offers different ratios of tungsten carbide (WC) and cobalt (Co), optimized for various combinations of hardness, strength, and impact resistance.

Q3: Which grade is suitable for high-impact or mining applications?

A3: YG15C and YG20X are specifically designed for high-impact environments. YG15C offers 3200 MPa in rupture strength, while YG20X provides enhanced impact tolerance and performance under high temperatures.

Q4: Can cemented carbide plates be used in corrosive or high-wear environments?

A4: Yes. Grades like YG6A are recommended for precision mold manufacturing and usage in corrosive conditions due to their fine grain structure and higher hardness.

Q5: Is customization available for plate size and shape?

A5: Yes. FOTMA supports manufacturing cemented carbide plates based on customer-provided dimensions and drawings, ensuring a perfect fit for your application.
