A bandsaw blade looks like a long piece of steel, but it is a very sharp tool. These blades are commonly used in workshops and machine shops where they are used for chopping various materials including metal and wood.

Aluminum is a nonferrous metal, with very low hardness, and it can be easily cut with the appropriate tools. When selecting a bandsaw blade for cutting aluminum, pay attention to the thickness of the aluminum. When cutting thick aluminum, use a blades with fewer teeth per inch. This type of blade is effective when piercing through thick material. However, when sheeting aluminum with thin-walled section, you should opt for a blade that is finer in terms of teeth per inch. This style blade works better for clean cuts in thinner materials.
Also, another thing to consider when selecting a bandsaw blade is the blade pitch. Pitch is the distance between each tooth on the blade. A higher numbered blade has teeth that are set closer together. This style of blade cuts faster, which is excellent if time is short. On the other hand, a higher pitch blade could chip or break more easily if you're not careful. Conversely, that of a lower pitched blade has teeth that is more distant. It will be slower cutting but less likely to chip and break, therefore making this a safer option to use for cutting aluminum.
When cutting aluminum with a bandsaw blade, it is critical to use proper cutting techniques. A good trick is to use a lubricant such as cutting oil, and apply it to the blade while cutting. This lubricant works to cool the blade and prevent it from overheating. A cooler blade means better blade longevity with reduced risk of chipping or cracking during cutting.
One of the helpful tips is to cut at lower speed. Cutting at a slower pace helps to minimize the risk of chipping and can also provide you with a more accurate cut. One such major difference between the two is that the final cut will be much more refined and accurate, which is essential in case a clean look approach is what you are looking forward to achieve in your project.
Secondly, we need to maintain the blade as well. This might entail keeping the blade well-honed so that it remains efficient. And you must inspect the blade regularly for wear or damage. If anything feels wrong with the blade, it might be prudent to replace. Doing so will allow for the optimal cutting performance and cleaning your cuts up to be smooth and accurate.
This can make cutting aluminum on an appropriate bandsaw blade of choice for you a little easier. First don’t forget, before you get cutting, to secure the aluminum piece tightly to the saw table. This is super important because like wood, if the aluminum moves when you're cutting, it can cause chipping or damage for the both the material and the blade.
