Customer Pain Points Analysis
The High Chrome Cr26 hammers currently used by customers are facing the following difficulties:
- Low Efficiency: The crushing efficiency significantly decreases as the hammer wears out, impacting overall production capacity.
- Short Lifespan: The single-sided usage time is only 16-20 hours, and frequent replacements negatively affect production efficiency.
- Cumbersome Replacement: Each hammer weighs 28.7 kilograms, making replacement time-consuming and labor-intensive, especially in harsh working environments.
The following are the scrapped high chrome hammers:
Innovative Solutions
We deeply understand the problems of customers and have developed a new carbide multi-layer composite hammer head:
- Multi-layer carbide design: Each layer of carbide grade has its own unique function, with super impact resistance and wear resistance.
- Brazing: The unique brazing process ensures the perfect fusion of multiple layers of materials, and the brazing surface is strong and durable.
- Customized structural optimization: Designed specifically for high-speed equipment, it improves the overall performance of the hammer head and adapts to extreme working conditions. We adopt a customized solution designed for each customer to help customers solve problems according to actual conditions.

Experimental comparison data
| Performance Indicators | Cr26 Hammer | Tungsten Carbide hammer |
| Single-side use time (hours) | 16-20 | >240 |
| Service life | 32-40 hours | >480 hours |
| Wear rate | Efficiency drops significantly after 10 hours of wear | Wear is significantly reduced, maintaining efficient operation of equipment for a long time |
| Replacement frequency | Frequently | Extremely low |
Test Results
The performance of our tungsten carbide hammer under actual working conditions:
- Eco-Friendly: Reduces the recycling and disposal of discarded high-chromium hammers, conserving resources and promoting environmental sustainability.
- Durability: After 150 hours of continuous operation, the equipment maintained efficient output, whereas the traditional Cr26 hammer required replacement three times.
- 15x Longer Lifespan: Testing shows that production lines using our full tungsten carbide hammer experience significantly fewer replacements, substantially reducing downtime.
- Enhanced Production Efficiency: Wear is significantly reduced, and crushing performance remains stable, leading to a noticeable improvement in overall productivity.
Company advantages
- Cemented carbide R&D and production: We have a complete cemented carbide R&D and production line, and control the quality from the powder.
- Welding: After 12 years of research and development, we have our own unique welding process and customized fully automatic welding equipment.
- Customer-centric: We develop customized solutions one-to-one according to customer needs.
Through this experiment, we can know that the cemented carbide vacuum brazing hammer customized and produced by our Old Craftsman is significantly superior to the traditional high-chromium hammer in terms of wear resistance, service life and production efficiency. Its higher hardness (HRA 89-91) and unique welding process significantly enhances wear resistance and reduces downtime caused by frequent hammer head replacement.
The carbide vacuum brazing hammer performs well in high impact and high wear environments. Its lifespan and performance are more than 15 times that of the high chromium hammer, which can greatly improve the production efficiency of the equipment while reducing resource waste and environmental burden.
