Advantages of Aluminum Machining

Aluminum is one of the most versatile manufacturing materials in the world, which is why it’s so popular in a wide range of industries. But why exactly is aluminum so suitable for CNC machining? Well, here are some of its main advantages:
  • Light Weight. Aluminum is one of the lightest metals available, weighing just over 2.7 g/cm3. That’s very useful for transportation, usability, and other practical reasons that are important in a range of industries.
  • Anti-Corrosive qualities. Anti-corrosive qualities are another significant advantage of aluminum, was it helps protect it from oxidation. That, combined with a range of finishes and coatings, ensures that your parts will serve you for a long time.
  • Conductivity. Aluminum has excellent qualities of thermal and electrical conductivity. That makes it suitable for a range of uses similar to copper and other conductive materials.
  • Convenient Machining. Another reason why aluminum is so popular is its ease of use with machining. The material is easy to shape, drill, and fold, allowing to create even the most complex shapes.
  • Temperature Resistance. Unlike some other material options, aluminum is resistant to low temperatures, meaning that the machining process is more flexible.

Frequently Asked Questions

In its pure form, aluminum is malleable, resistant to corrosion in most forms, non-magnetic, and an excellent conductor of heat and electricity. However, it is too weak for most commercial applications.

Greater strength can be achieved by combining molten aluminum with other elements such as copper, lithium, magnesium, manganese, silicon, and zinc to form alloys. These alloys also further enhance aluminum’s other natural properties.

The most commonly used alloys in aluminum CNC machining are divided into three categories:

Cast aluminum alloy – Casting refers to molten or liquid forming. Producers form this type of alloy by pouring molten aluminum into a mold and cooling it. Cast aluminum alloys are affordable, versatile, lightweight, durable, and perform well at high temperatures.

The automotive industry is the largest user of cast alloys, accounting for about two-thirds of the aluminum used in automobiles. Parts made of cast alloys include engine parts, housings, steering columns, and increasingly structural brackets. Other common uses include cookware, mechanical parts, and hand tools.

Cast alloys are less expensive to produce due to their low melting point and can produce a wider range of shapes due to the flexibility of the mold. But their tensile strength tends to be lower than that of forged alloys, is not easy to machine, and is more wear-resistant on cutting tools.

Aluminum-lithium (Al-Li) alloy—Lithium is the lowest density elemental metal, making this type of alloy much lighter than pure aluminum or other materials. Due to this property, the aerospace industry mainly uses Al-Li alloys for lower wing skins, inner wing structures, fuselages and fan blades. You can also find them in racing cars and space rockets.

The weight advantage offered by Al-Li alloys is offset by their lower machinability and lower fracture toughness (the ability of crack-containing materials to resist further cracking). Their production is relatively small, which also means they are more expensive.

Forged aluminum alloy – Forging refers to forming under solid state. This type of alloy is produced by forming molten aluminum into billets or large slabs and then using tools to roll, forge, stamp, or extrude these pieces into shape.

Forged alloys are the most widely used material in aluminum CNC machining. This is because they have superior mechanical properties and structural integrity compared to cast alloys. They are easier to machine, have a better surface finish, and have less wear on the edges of the cutting tool.

Aluminum and steel are the most widely used metals in CNC machining. Choosing the right approach for a particular application boils down to five factors:

1. Cost — Mild and carbon steels are generally cheaper than aluminum equivalents. Stainless steel tends to be more expensive. However, the price of metals depends on global demand and the cost of raw materials, energy and transportation.

When considering cost, it is also important to consider the durability of the material. A decision that might save money in the short term can cost more in the long run.

2. Corrosion resistance — Both aluminum and stainless steel are highly rust and corrosion-resistant. However, stainless steel is a more expensive option. Manufacturers or end-users will need to paint, treat, or coat every other type of steel to protect it, especially if they intend to expose the finished part to the elements. These coatings imply additional weight and cost, and also need to be reapplied periodically, but at a further cost.

3. Weight — Aluminum is two to three times lighter than steel. Almost every company wants to achieve the same or better product performance while adopting lighter materials. This “lightweighting” trend has led manufacturers to replace many parts previously machined from steel with aluminum.

4. Strength — Steel may be heavier than aluminum, but this makes it a more durable material. Steel is very strong and less likely to warp, bend, or otherwise deform under force, heat, or weight. In addition, the surface of aluminum is more prone to scratches and dents than steel.

5. Machinability — Lower density than steel means aluminum can be machined three or even four times faster. Aluminum also cools faster than steel; This reduces the time required to machine the part (cycle time) and the amount of coolant required.

Compared to steel, aluminum requires much less cutting force. This reduces wear on cutting tools, helping to make them sharper and last longer. It is also possible to CNC aluminum on smaller machines, so it may be cheaper.

CNC milling machines are the most common and versatile way to process aluminum parts. The machine uses a rotary cutting tool to efficiently and precisely engrave material from stationary blocks of material.

Thanks to the advent of computerized numerical control (CNC) systems, automatic tool changers and tool conveyors, traditional milling machines were transformed into “machining centers” in the 1960s. These machines are available in 2- to 12-axis configurations, although 3- to 5-axis are the most widely used.

CNC metal lathes or CNC metal turning centers hold and rotate the workpiece firmly, while cutter bits hold the cutting tool or drill. These machines can remove materials very precisely, and manufacturers use them in a wide range of industries.

Typical lathe operations include drilling, shaping, grooving, tapping, threading, and tapering. CNC metal lathes are rapidly replacing older, more manual production models due to their ease of setup, operation, repeatability, and accuracy.

CNC plasma cutters heat compressed air to very high temperatures to create a “plasma arc” capable of melting metal up to six inches thick. The plates are laid flat on the cutting table, and the computer controls the path of the torch head. Compressed air blows away the hot molten metal, which cuts the material. Plasma cutters are fast, precise, relatively easy to use, and affordable, and manufacturers use them in many industries.

CNC laser machines melt, burn, or evaporate materials to form cutting edges. Similar to plasma cutters, the plates lie flat on the cutting table and the computer controls the path of the high-power laser beam.

Laser cutters use less energy than plasma cutters and are more precise, especially when cutting thin plates. However, only the most powerful and expensive laser cutters can cut thick or dense materials.

CNC water cutting machines use extremely high-pressure water jets to force material to be cut through narrow nozzles. Water alone is enough to cut soft materials such as wood or rubber. To cut hard materials such as metal or stone, operators often mix abrasive substances with water.

Water cutters do not heat materials such as plasma and laser cutters. This means that the presence of high temperatures does not burn, warp or change its structure. It also helps reduce waste and allows shapes cut from the plate to be placed (or nested) more closely together.

Aluminum is the most abundant metallic element in the earth’s crust. The metals industry smelts more than 40 million tons per year, and manufacturers use them for a variety of applications.

Like most metals, aluminum is found as an ore in rocks throughout the earth’s crust. Mining companies extract almost all of their aluminum metal from bauxite, which typically contains 30 to 60 percent alumina (or alumina). The rest is a mixture of silica, various iron oxides and titanium dioxide.

Two-step process to convert alumina to aluminum:

1. Extraction of alumina from bauxite

Almost all of the world’s alumina supply is produced using the Bayer process. Austrian chemist Carl Josef Bayer developed this technique in the late 19th century.

It involves crushing bauxite into a fine powder, mixing it with water and heating the mixture with caustic soda. Caustic soda dissolves the alumina and passes it through the filter.

Producers add aluminum hydroxide crystals to an alumina solution, which is then heated and dried to produce alumina.

2. Smelting alumina to produce aluminum metal

To smelt aluminum, refineries dissolve alumina in a fluorinated bath and use an electric current to break it down into metallic aluminum and oxygen through a process called electrolysis. They then collect the aluminum and take it to a furnace, where they combine it with the recycled aluminum material and heat it until it is melted.

It is then poured into a mold or mechanically extruded in various forms. The most common are plates, billets, bars, tubes, plates, bars and wires. They are then cut into different shapes and sizes and shipped to another company or manufacturer who will process them into countless products.
