Zirconia ceramic punch

Zirconia ceramic punches are high-performance mold components made from zirconia (ZrO₂) material, possessing the following core characteristics and application advantages:

Material Characteristics

1. High Hardness and Wear Resistance: Zirconia ceramics have a Mohs hardness of 8.5, approaching that of sapphire, significantly superior to metal materials, making them suitable for high-friction environments. Their fracture toughness is 1-35 MPa·m¹/², providing excellent impact resistance.

2. High Temperature and Corrosion Resistance: With a melting point of up to 2715℃, they can operate stably in high-temperature and high-pressure environments, and also possess resistance to acid and alkali corrosion.

Application Scenarios

1. Industrial Molds: Used in precision machining components such as punch pins and ceramic punches, extending mold life.

2. Mechanical Seals: Used as bearing and sealing materials, suitable for harsh working conditions.

3. Electronics and Medical Devices: High insulation and biocompatibility make it suitable for medical devices and electronic components.‌

Technological Advantages

1. Extended Lifespan:  Wear resistance is 3-5 times higher compared to traditional metal punches.

2. Customized Service:  Supports processing based on drawings or samples, and offers a variety of color options (such as white and black).

Supports custom specifications.
