Tungsten Carbide Blocks for Heavy-Duty Tooling

Introduction

Tungsten carbide blocks are large, thick carbide blanks used to manufacture heavy-duty stamping dies, forming tools, anvil blocks, and wear surfaces. Their size and material properties make them ideal for demanding applications.

Available Sizes

Carbide blocks range from small rectangles to large custom blocks. Standard thicknesses start at several millimeters, with large blocks exceeding 50 millimeters thick. Custom dimensions are produced to order.

Grade Selection

Medium and coarse-grain grades are typically used for blocks, balancing hardness with toughness. Fine-grain grades are used for precision stamping blocks. The grade depends on the expected loads and wear.

Applications

Carbide blocks are used for stamping die sets, forming dies, wire drawing capstans, anvil blocks, shear blades, and wear plates. They serve automotive, construction, and metalworking industries.

Precision Grinding

Blocks can be surface ground to tight flatness and parallelism tolerances. Both top and bottom surfaces can be lapped or polished for precision die sets. Side surfaces can be ground or EDM as needed.

Custom Shapes

Beyond rectangular blocks, custom carbide shapes including holes, chamfers, and profiles can be produced. Wire EDM and sinker EDM enable complex geometries in large carbide components.

Conclusion

Tungsten carbide blocks provide the foundation for heavy-duty tooling where steel cannot withstand the loads and wear. Custom sizes and grades ensure the right solution for each application.
