Cemented Carbide Plate for Industrial Cutting and Wear Protection

1. Product Overview of Cemented Carbide Plate

Cemented carbide plate is produced by powder metallurgy using tungsten carbide powder and metallic binders.

The material provides high hardness, high compressive strength, and strong resistance to abrasion and impact.

It is suitable for demanding industrial environments where steel materials cannot achieve long service life.

Main Material Properties

High hardness ensures strong wear resistance in cutting and forming operations.

Excellent compressive strength supports heavy-load industrial applications.

Good corrosion and heat resistance maintain stable performance under harsh conditions.

2. Applications of Carbide Plate

Industrial Wear Parts

Used as wear-resistant liners and protective base plates in mining and metallurgy equipment.

Provides long service life in abrasive working conditions.

Cutting and Forming Tools

Used for manufacturing cutting tools, stamping dies, and drawing dies.

Ensures stable cutting performance and high precision in machining processes.

Heavy Industry Applications

Applied in oil and gas, construction machinery, and mechanical engineering systems.

Suitable for high-wear and high-impact working environments.

4. Processing and Manufacturing Notes

Cutting Methods

Carbide plate cannot be processed with standard saw tools.

Waterjet cutting and wire EDM are commonly used for shaping.

These methods ensure precision without damaging the material structure.

Thermal Crack Control

Uneven heating can cause internal stress and cracking.

Stable cooling and proper grade selection help improve durability.

5. Quality and Material Selection

Binder Types

Cobalt binder provides high strength and wear resistance.

Nickel binder offers improved corrosion resistance for chemical environments.

Grade Selection

Fine grain grades are suitable for abrasion resistance applications.

Coarser grain grades are better for impact-heavy working conditions.

FAQ about Cemented Carbide Plate

1. What is the difference between a "Plate" and an "Insert"?

Inserts are small cutting tips used on CNC tools such as milling cutters and turning tools.

They usually have complex chip-breaking geometries.

Plates are larger flat carbide materials used for wear protection, structural parts, and custom tooling bases.

2. Why are carbide plates so expensive compared to steel?

The cost comes from raw materials and processing.

Tungsten and cobalt are high-cost materials with volatile market prices.

Production requires high-temperature sintering and diamond grinding, which increases manufacturing cost.

3. Can I cut a carbide plate to size myself?

Standard saw tools cannot cut carbide plates.

Waterjet cutting is commonly used for shaping.

Wire EDM is preferred for high-precision machining without mechanical stress.

4. How do I prevent thermal cracking in large plates?

Thermal imbalance can cause internal stress and cracking.

Stable cooling and proper material grade selection are important.

Higher cobalt content grades can improve thermal shock resistance.

5. Can I tap threads into a carbide plate?

No, carbide cannot be tapped using standard tools.

Holes must be pre-formed during production or machined using EDM.

Threaded inserts or through-bolt designs are usually required.

6. Why is my plate leaching or turning pitted?

This happens when cobalt binder is exposed to moisture or chemical fluids.

The binder dissolves and tungsten grains become loose.

Nickel-binder grades offer better corrosion resistance in such environments.

7. Is a thicker plate always better for wear?

Not always.

Thicker plates increase wear life but also increase internal stress risk.

In some cases, carbide combined with a steel backing is more effective.

8. How do I know which grade to choose?

Selection depends on working conditions.

Fine grain grades are suitable for abrasion resistance applications.

Coarse grain and higher cobalt grades are better for impact-heavy conditions.
