In our daily lives, we often use wood products such as wooden tables, chairs, beds, etc. These need to be done through a series of processes. The saw tips are usually welded on the band or circular saw to save cost and prolong the service life. Commonly, the material of the saw tips is carbide, Cobalt alloy and high-speed steel, each with its advantages.
Traditionally, cobalt alloy-tipped bandsaws were used for cutting hardwoods, but they have also been proven to be used on softer woods such as Fir & Pine. Due to its excellent corrosion resistance performance, it can cut wood like redwood and unseasoned wood.
Cobalt alloy is a material with high-temperature resistance, wear resistance, and corrosion resistance. The following two kinds of common cobalt alloy grades exist for the woodcutting industry.
| NO. | C | Mn | Si | Cr | Ni | Mo | W | Co | Fe | Density ≥(g/cm³) | Hardness (HRC) |
| Co 1 | 2.2-2.8 | – | 2.0 | 29.0-33.0 | 3.0 | 1.0 | 11.0-14.0 | Bal. | 3.0 | 8.55 | 51-55 |
| Co 12 | 1.1-1.7 | 1.0 | 1.0 | 28.0-32.0 | 3.0 | – | 7.0-9.5 | Bal. | 3.0 | 8.4 | 41-49 |
The Advantage of cobalt alloy saw tips:
- It can give considerably longer operation time
- It provides better surface finishes
- It has excellent wear resistance and is tough enough to withstand shocks caused by knots, nails, etc.
- It’s cut kerf is thinner
- It has better cutting accuracy
- It has smoother cutting edges
