The material characteristics of bi-metal bandsaw blades are their bi-metal structure: B318 backing material with high fatigue strength; and M42 tooth material with 8% cobalt content, resulting in a tooth hardness of HRC67-69.
The main advantages of bi-metal bandsaw blades are:
1. High wear resistance and high hot hardness;
2. Teeth are less prone to breakage;
3. Long service life.
