Cutting Aluminum with Alloy and Diamond Saw Blades   Understanding Aluminum Cutting   Aluminum profiles need compatible blades to get precise shapes. Cutting a soft metal like aluminum seems to be easy unless you face problems with its edges and depth. Too much heat can deform not only aluminum but also blades. This is why you must know the nature and material of the cutting blade along with compatible designs. Here is a comparison between a diamond saw blade and an alloy saw blade when cutting aluminum either for aluminum profiles or any other part.   Alloy Saw Blades When you have to cut soft metal like aluminum, hard metal cutting blades will be suitable. Alloy saw blades will give enough strength and resistance to shape aluminum. Different types of metals like high-speed steel, titanium, and carbide contribute to the toughness level. Also, they are cost-effective metals, which make the blade affordable for users. A hard-alloy blade can help you cut aluminum since it does not get deformed. It cuts aluminum easily since its hardness is much higher than aluminum. Alloy saw blades are good at sharp cutting with precision and control. One thing you can note down is that it can do high heat generation. That can cause a risk of teeth damage, and users have to take breaks to cool down saws.   Applications If you are working on simple designs, alloy saw blades will be suitable. They can cut down the aluminum into desired shapes without causing much friction for the blades. This is an Ideal scenario for using alloy saw blades on aluminum. Unless you have to go for intricate designs, it is better to keep using this type.  Performance Their cutting speed is fast enough to give you the desired results. HSS (high-speed steel) makes it suitable for that performance. This performance remains impressive as long as you keep giving breaks to allow saw blades in the process. Otherwise, overheating will cause damage to blades like deformity or teeth reduction.   Diamond Saw Blades Nothing can beat diamond saw blades when it comes to strength and durability. If you compare it with alloy saw blades, there is a major difference between them. Diamond-tipped blades have metal bodies with diamond tips. Those teeth or tips can deal with not only aluminum but also other types of metals. Both soft and hard metals can be cut into any desired shape with the hardness level of these blades. They have much more hardness than alloys, which makes them the best against aluminum. Their heat resistance is also better because diamonds can bear heat at high levels. This is why it has no or the lowest risk of deformity. You will find high corrosion resistance in them, which makes them durable.  Getting precise cutting from diamond saw blades will be easier than alloy type.  Although it is a more expensive option, you will find better results with it. Doing high-speed machining with a diamond saw blade will be safer since it does not shatter easily. Applications When you have to deal with thicker aluminum plates, it is better to choose diamond saw blades. The reason is the friction level, which increases heat generation on the blades. Diamond saw blades can cut soft metals as well as concrete better. This is why cutting aluminum of any thickness level will be a better idea with these blades.  Performance The longevity level is much higher when you go for the diamond type. Their hardness and resistance level make them perform at a higher rate. They are corrosion-resistant, which makes them free of rust. Diamonds can run well in wet as well as dry cutting. You can’t rely on an alloy blade for wet cutting as it will corrode soon.   Choosing the Right Blade   Upon extreme conditions and high pressure, the alloy blades may shatter. On the other hand, a diamond blade might not. When cutting aluminum, you have to look at this condition. The alloy blade is good against soft metals only. However, diamond blades can deal with soft and hard metals. In this way, you may have to bear extra costs in the diamond type but the performance will be better than the alloy type.   Factors to Consider There are different factors that you need to consider when selecting saw blades.  The thickness of aluminum matters here because it will affect the teeth performance of blades. If the thickness is high, an alloy blade might not be a good option. You will need a diamond type to deal with friction and heat caused by high thickness levels. When dealing with straight cutting, you can choose an alloy blade. After all, both types will be suitable for that. However, if you want intricate designs, a diamond blade will be a better option. The reason is the precision, which you can get from diamond type. If the frequency of use is very high, the diamond blade can survive for a longer time. It is because of its heat and corrosion resistance. Also, its hardness prevents its teeth from wearing out soon. If you look at the budget, a diamond blade will be an expensive option. If you want a less expensive blade, an alloy type will be suitable. However, more than budget, it should be about performance level. Recommendation If the aluminum plate is not very thick, you can choose alloy over diamond. That will be suitable in the case of simple shapes and low-friction cutting. Also, if you are low on budget, an alloy will be more affordable for simple operations.    Maintenance Tips   There are some maintenance tips, which will help you extend the life of blades. If you ignore the maintenance, you will not get the desired performance from blades for a long time.   Caring for Your Saw Blades Use a fabric or brush to keep removing debris from the blade at intervals. That will reduce the wear and tear from it. Also, always clean it before packing it back in the box or fabric bag. Do not expose any saw blade to air consistently because it will corrode the blade. It is better to approach an expert who has resharpening machines. They can restore the sharpness of blades by honing them in a balanced way. Since it is about uniformity of teeth, a machine will give balanced treatment to blades. Avoid overheating by taking small breaks in the cutting process. Overheating will deform the teeth as well as they can fracture them. This will deform aluminum also because it can not bear much heat continuously.  Conclusion   It all depends on the type of cutting you will do on aluminum plates. All the conditions have been described above, which will let you understand better. After that, you can select the blades accordingly.
