Aluminum alloys are characterized by several things. Perhaps their most famous attribute is their low weight that makes them ideal for use in areas where reduced weight is important. A natural oxide layer forms on the aluminum alloy’s surface, making it corrosion resistant and keeping it protected in all different environments. In spite of their low density, they are strong and durable, factors that make them useful in projects where strength and weight have to be carefully balanced. They can also be easily shaped and formed, making them a versatile material for those in manufacturing to work with. For example, aluminum 5052 is especially malluable and a popular alloy with our sheet metal customers, where aluminum 6061 is extremely popular for CNC machined parts due to its machinability and balanced characteristics.

5000 Series: The main alloying element in the 5000 series is magnesium. These versions of aluminum can be found in vehicles, pressurized vessels, and bridges. Specifically, aluminum 5052 is a very common choice among our customers for bent sheet metal parts.

Naturally occurring compounds that contain aluminum have been known since antiquity, but aluminum’s elemental nature as a metal wasn’t confirmed until 1825 as a result of the combined efforts of German chemist, Friedrich Wöhler, and Danish physicist, Hans Christian Ørsted. It was soon realized that aluminum was a hard material to process, and it was also expensive—at the time, it cost more than gold! The price of aluminum alloy only started to go down in 1856 when Henri Étienne Sainte-Claire Deville, a French chemist, found a way to make it on a large scale. Fifty years later, duralumin (the first structural aluminum alloy with a good amount of strength) was created and developed for military and industrial purposes.

Secondary relief is an additional relief angle ground into the back of the cutting tool, which can help to reduce the risk of chipping or breakage, stabilize cutting edges and increase clearance. This can be particularly important when machining titanium, which can be highly difficult to work on. With todays advanced designs, you’ll find many tools utilizing eccentric ground edges specifically targeted toward titanium. These designs offer the proper clearance behind the eccentric relief. They are very effective and tend to feature a stronger edge and last longer. Kennametal’s HARVI™ III high-performance aerospace end mills are only one example of what is offered in the line.

It’s worth noting that aluminum alloys do have some limitations. For one, they have a lower melting point than most other structural metals, which means they won’t be the best fit for high-temperature tasks. They’re not as hard as other metals, so won’t likely survive as much wear and tear. Certain alloys can also be quite expensive, so they might not be as cost-effective as other materials in certain situations.

During machining, the thickness of the chips being produced can vary from thick-to-thin. This can have a significant impact on the machining process, as thick chips can cause problems with chip evacuation and tool wear, while thin chips can help reduce heat generation and improve surface finish. Understanding the effects of thick-to-thin chip formation is important when milling titanium, as it can help you adjust your machining parameters and achieve better results.

When machining titanium, it is essential to use tools that are specifically designed for the material. Titanium is extremely hard to machine and can quickly wear down inferior cutting tools, resulting in poor surface finishes, tool breakage, and other issues. Look for cutting tools made from high-performance materials such as carbide, which can withstand the high temperatures and pressures generated during titanium machining. You should also choose tools with a high number of teeth to reduce the load on each tooth and prevent tool wear.

What isan alloy

When dealing with thick-to-thin chip formation, it is important to pay attention to the chip breaker design on the cutting tool. A chip breaker is a groove or notch on the cutting edge that helps to break up the chips into smaller, more manageable sizes. A well-designed chip breaker can help to prevent these issues and improve overall machining performance.

Tool deflection can occur when the cutting tool bends or flexes during machining. This can result in poor surface finishes, tool breakage, and other issues. To avoid tool deflection, use cutting tools with a higher number of teeth, and consider reducing the cutting depth or width to reduce the load on each tooth of the cutting tool.

Arc In is the steady entry of the tool into the workpiece, while chamfer is the angle at the cutting edge of the tool. Both factors can have a significant impact on the performance of your cutting tool when machining titanium. Make sure when machining to program thick-to-thin-arc instead of a straight path which will help avoid sudden jarring changes in cutting forces. And program your chamfer to avoid unstable left-over materials.

It's important to adjust your feed and speed settings to achieve optimal performance. Lower cutting speeds may be necessary to maintain a consistent cutting temperature when used on titanium. However, it's important to balance this with an appropriate feed rate to ensure that you achieve optimal chip evacuation and prevent excessive tool wear.

Depending on the alloying element and specific composition, aluminum alloys have different physical and chemical properties. We’ve prepared the below tables to summarize some of these common properties.

Titanium is a strong, lightweight metal ideal for a range of applications. However, it can be difficult to machine due to its high strength, low thermal conductivity, and chemical reactivity.

Composition of an alloywikipedia

Aluminum alloy offers a great many benefits—there must be a good reason for its mass popularity, after all. Aluminum is much lighter than other metals, which makes it ideal for use in applications where low weight is important. Aluminum alloy has a high strength-to-weight ratio, and is much stronger than many other materials of a similar density. They’re great for marine and industrial settings, or other harsh environments, as they have excellent corrosion resistance. Most are also highly ductile, allowing them to be easily shaped without breaking or cracking. Finally, aluminum alloys make good thermal conductors as they can efficiently transfer heat.

1000 Series: Pure aluminum makes up at least 99% of the 1000-series alloys’ composition, with only traces of other elements. The precise composition and impurity content of the various alloys in the 1000 series is what differentiates them from one another. These alloys are very thermally conductive, highly ductile, and corrosion-resistant, and are used in products like chemical tanks, conductive bus bars, and rivets.Â

Many consumer goods are made with aluminum alloys, again, thanks to their minimal weight, ability to resist corrosion, durability, strength, and recyclability. Automobile parts, cookware, electronics, and beverage cans are just a few of the products that are usually made of aluminum.

Coolant pressure plays an important role in machining titanium. It is a difficult material and generates a significant amount of heat during cutting. Using high-pressure coolant can help reduce chip adhesion by flushing them away from the cutting area and cooling the workpiece and cutting tool. Additionally, using a chip conveyor or other means of automatic chip removal can further improve chip evacuation and reduce the risk of tool breakage.

Many medical devices and equipment need to be made from durable, strong, and corrosion resistant, making aluminum alloys a perfect fit, and commonly used to make wheelchairs, hospital beds, and surgical instruments.

This article offered an in-depth look at aluminum alloys, what they are exactly, their pros and cons, the different types of aluminum alloys available, and their various applications and benefits.Â

Listofalloys and theircompositionand uses

Aluminum alloys come in seven different categories, according to their chemical makeup, primary alloying elements, and physical characteristics. These are:

Climb milling, or thick-to-thin chip formation is the ideal way to make sure you are getting the proper results. It begins with the cutting edge entering the excess material and exiting on the finished surface – meaning the cutter tries to climb over the material, ensuring that thick chips absorb cutting heat, decreasing adhesion from cutting pressure and the thin chip exits effectively. The exception to this is to conventional mill when you have an Alpha case in order to remove the thick harden skin, shearing from the softer surface below to create a clean surface, and then revert back to climb milling once the skin is removed.

As one of the most popular and commonly used metals in manufacturing, aluminum is loved for its low weight and strength-to-weight ratio. To make aluminum suitable for use in different industries, the metal is combined with other elements to form alloys. Aluminum alloys come in many different forms and are used in all kinds of products, including consumer electronics, packaging, and vehicle and plane parts.Â

4000 Series: Silicon gives this aluminum alloy excellent molten fluidity and minimal shrinkage when it solidifies, making it a great candidate for casting applications. It has good machinability and corrosion resistance and a moderate amount of strength. It is usually used for engine blocks and other auto parts that need to disperse heat efficiently.

3000 Series: Manganese improves the metal’s corrosion resistance and formability. 3000 series alloys have moderate strength but are not heat-treatable. They are used in cookware, automotive parts, and construction materials, and also work well when welding and anodizing.

2000 Series: The primary alloying element in the 2000 series is copper, which provides higher strength, but the exact amount of copper and other trace elements vary from one 2000 series alloy to another. Copper alloys can be machined, heat-treated, and withstand high temperatures. They’re often used in military, aerospace, and other high-performance applications. For more information on this material, see our guide on Copper.

Radial engagement is an important factor to consider when milling titanium. This refers to the amount of the cutting tool that is in contact with the workpiece at any given time. When radial engagement is decreased, the surface speed can be increased to maintain the optimum temperature at the cutting point.  By optimizing the radial engagement, you can improve chip evacuation and reduce the load on each tooth of the cutting tool, which can increase tool life and improve surface finish.

Coatings and grades can be highly effective in improving the performance of cutting tools when machining titanium. Titanium nitride (TiN), Titanium Carbonitride (TiCN), Titanium Aluminum Nitride (TiAlN), Aluminum Titanium Nitride (AlTiN), and Aluminum Chromium Nitride (AlCrN)   are common coatings for cutting tools, as they offer improved wear resistance and reduced friction. However, there are more advanced coatings that have multiple layers and provide more protection against chip building and tool wear. For example, high-performance solid carbide end mills used in aerospace applications can help you improve performance when machining titanium.
