What are the effects of high-purity iron powder on hot-pressed sintered blades?
Many customers are now switching from cold-pressed blades to hot-pressed sintered blades to improve the performance of saw blades. When communicating with Sagwell's technical personnel, they often ask about the impact of high-purity iron powder on products after this process transformation.

The technical personnel of Sagwell have sorted out the following points for reference:
-
- Improve the Wear Resistance and Service Life of Tools
-
The high strength, high toughness, and high holding force brought by high-purity Iron Powder directly make the matrix itself more wear-resistant, while enabling more persistent and effective fixation of diamond particles. This means:
The diamond of the hot-pressed sintered blade can give full play to its grinding effect until it is worn or broken, rather than falling off in advance.
The matrix has stronger resistance to wear from processing materials, maintaining shape and dimensional stability for a longer time.
The comprehensive result is that the overall wear resistance of the tool is improved, and the service life is significantly prolonged.

- Improve Tool Sharpness and Processing Efficiency
-
Higher holding force means that diamond particles are not easily "pulled out" or abnormally displaced under cutting force, allowing them to participate in cutting more stably.
Ultra-fine high-purity iron powder helps form a denser and more uniform matrix, making the diamond exposure height of hot-pressed sintered blades more consistent and controllable. Combined with good holding force, this helps the tool maintain sharpness, achieve smoother cutting, higher processing efficiency, and possibly better processing surface quality.

- Reduce Dependence on Sintering Atmosphere/Allow More Flexible Atmosphere Control
-
High-purity iron powder (especially low-oxygen iron powder) has a low degree of oxidation itself, releasing less gas during the sintering process, which relatively reduces the harsh requirements for the sintering atmosphere (such as reducing atmosphere). This simplifies process control and may allow good performance to be obtained under a wider range of atmospheric conditions.
-
Whether in terms of processing efficiency or other aspects, the effect of adding high-purity iron powder to the matrix of hot-pressed sintered blades is remarkable. Sagwell also welcomes everyone to communicate.
