What kind of ultrafine iron powder and pre-alloyed powder is better for ceramic cutting blade matrix?
When selecting ultrafine iron powderand pre-alloyed powder for ceramic cutting blade substrate, it is necessary to comprehensively consider various factors such as particle size, purity, activity, formability, cost, etc. of the Iron Powder and pre-alloyed powder.
The following are Sagwell's comparative reviews and recommendations for different types of foundation:
1. Basic characteristics of ultrafine iron powder
Particle size:
generally in micron level, such as 2~20 microns. The finer the particle size, the better the activity in the ceramic cutting blade matrix, which helps to improve the cutting performance.
Purity:
High-purity powder can reduce the impact of impurities on cutting performance and improve cutting efficiency and stability.
Activity:
Highly active iron powder is easier to combine with other materials to form a dense matrix structure, thereby improving the strength and wear resistance of the cutting blade.
Formability:
Good formability helps iron powder form a uniform matrix structure during the manufacturing process of ceramic cutting blade, ensuring the stability and durability of the cutting blade.
2. Evaluation of different types of ultrafine iron powder
Pure ultrafine iron powder:
Advantages: strong toughness, high viscosity, after specific process treatment, it can produce ceramic cutting discs with excellent performance.
Disadvantages: The diamond edge is exposed slowly, and its red hardness is poor after heating, which affects the cutting efficiency and sharpness.
Application: Suitable for dry cutting of medium hardness tiles, such as glazed tiles, polished tiles, etc.
Iron-cobalt pre-alloyed powder:
Advantages: Contains a certain amount of cobalt, which improves the activity and formability of iron powder, while enhancing the holding force and cutting effect of diamond.
Features: Good self-sharpening, can quickly form diamond blades and maintain diamond retention. Low sintering temperature is conducive to reducing energy consumption and costs.
Application: It is suitable for manufacturing ultra-thin ceramic cutting discs. It can continuously dry-cut high-hardness full ceramic tiles. The flatness and edge collapse of the tiles after cutting are good.

3. Select suggestion
Choose according to cutting requirements:
For occasions where high-hardness tiles need to be cut, it is recommended to choose iron-cobalt pre-alloyed powder containing cobalt elements to improve cutting efficiency and stability. For cutting tiles of medium hardness, pure iron-based ultrafine iron powder is also a good choice.
Consider the cost factor:
the price of cobalt is relatively high, so the cost of iron-cobalt pre-alloyed powder may be relatively high. If the budget is limited, you can choose lower-cost pure iron-based ultrafine iron powder according to actual needs.
Pay attention to process matching:
When selecting ultrafine iron powder, you also need to consider its compatibility with the existing manufacturing process to ensure that the selected iron powder can meet the requirements of the manufacturing process to improve production efficiency and product quality.
Therefore, the selection of ultrafine iron powder and pre-alloyed powder for ceramic cutting blades needs to be comprehensively evaluated based on specific cutting requirements, cost factors, process compatibility, etc. In the selection process, you can refer to the above suggestions to ensure that the selected iron powder can meet the manufacturing requirements and performance of ceramic cutting blades.
