Selection of suitable saw blades for aluminum and aluminum alloys
What is aluminum material?
Why are more and more industries using aluminum metal for manufacturing? Aluminum is a lightweight metal with good electrical and thermal conductivity. It has many advantages such as being light, corrosion-resistant, and recyclable. Aluminum can be widely used in various industries, such as construction, automotive, aerospace, packaging, etc. Aluminum mainly exists in the form of oxides or silicates and is generally found in soil or rocks.
How to choose the right saw blade for cutting aluminum?
Choosing aluminum as the material for the saw blade is a good choice because it requires better cutting ability and cutting speed. Here are some key points to consider when selecting a saw blade:
1. Material: Choose saw blades made of carbon steel, high-speed steel, tungsten steel, and other materials. Among them, high-speed steel and tungsten steel are more suitable for high-hardness aluminum, while carbon steel is suitable for softer aluminum.
2. Teeth pitch: Use dense and small teeth pitch for aluminum to improve cutting speed and efficiency. Generally, a saw blade with 20 to 24 teeth per inch works best.
3. Tooth shape: Choose tooth shapes with large and deep grooves and negative angles to remove aluminum chips during cutting. This can effectively reduce jamming and heat.
4. Blade thickness: It is recommended to choose a thin and hard saw blade to reduce the possibility of vibration and deformation and to increase accuracy and cutting speed.
5. Surface coating: If high-strength and long-term cutting is required, select saw blades with specially treated surfaces, such as aluminum oxide and molybdenum coating. These coatings can reduce wear and friction and increase the service life of the saw blade.
Recommended saw blades:
1. Bosch T118AHM 3 Inch 24 TPI Bi-Metal Jig Saw Blade for Aluminum
This saw blade is manufactured by Bosch and is made of bi-metal design, which has excellent cutting power and durability and is suitable for cutting multiple materials. It has a teeth pitch of 24 TPI and a unique tooth design that can avoid jamming and improve cutting speed and accuracy.
2. DEWALT DW3750H 4 Inch 10 TPI Aluminum Cutting Jig Saw Blade
This saw blade is manufactured by DEWALT and is made of high-speed steel, suitable for cutting aluminum. It has a teeth pitch of 10 TPI and a unique tooth design that can improve cutting efficiency and reduce the risk of jamming. The thinner blade can also reduce the possibility of vibration and deformation and increase accuracy and cutting speed.
3. Milwaukee 48-42-5210 3 Inch 10 TPI Bi-Metal Jig Saw Blade for Aluminum
This saw blade is manufactured by Milwaukee and is made of bi-metal design, which has strong cutting ability and durability and is suitable for cutting aluminum. It has a teeth pitch of 10 TPI and a unique tooth design that can avoid jamming and reduce aluminum chips during cutting. It also uses special coating technology to improve the performance and service life of the blade.
Choosing an aluminum saw blade is a great choice, but it is important to consider material, teeth pitch, tooth shape, etc. Material selection is still more important. For example, carbon steel and high-speed steel have different properties, and you need to choose according to your needs. The above recommended saw blades all have excellent performance in cutting aluminum and can meet the needs of different users. However, please pay attention to safety and correct operation methods when cutting to ensure safety.
