Advantages of Tungsten Carbide Material
- High Hardness: Reaching HRA 88-92, significantly surpassing ordinary tool steel.
- Excellent Wear Resistance: Lifespan can be 3-5 times that of DC53.
- Good Dimensional Stability: Machining accuracy can be controlled within ±0.001 mm.
- Excellent Compressive Strength: Suitable for high-strength stamping operations.
- Good Surface Finish: Capable of achieving high mirror effects.
Characteristics of DC53 Tool Steel
- Economical Price: Low initial investment cost.
- Ease of Processing: Less difficulty in processing, resulting in a shorter manufacturing cycle.
- Better Toughness: Not prone to brittleness.
- Mature Heat Treatment Process: Hardness can reach HRC 60-62.
- Convenient Maintenance and Repairs: Relatively easy to maintain.
Recommendations
Based on practical production experience, for large-scale, high-precision rivet production, Tungsten Carbide is recommended for die manufacturing. Although the initial investment is significant, over the long term, its excellent wear resistance and stable performance offer a higher cost-performance ratio. For small-scale or experimental production, DC53 is a more economical choice.
Selecting the appropriate die material requires consideration of product characteristics, production volume, precision requirements, and the usage environment. As a professional manufacturer of carbide products and an expert in mold manufacturing, we can provie the best material solutions according to specific customer needs.
