However, it is more expensive to work with compared to aluminum. The titanium also carries double the strength for a similar weight.

While many companies’ best-preferred mode is CNC machining aluminum, the metal has limitations that make some companies opt for other materials.

Amongst all the aluminum brands, this is the softest brand. Its strength to weight ratio is a bit low. It is mainly used to form applications and marine applications.

Aluminum CNC milling is a process of using aluminum for manufacturing a product. The process involves using computerized controls and a CNC router to operate and manipulate machine tools using aluminum to cut and shape stock material.

Aluminum is known to have tight tolerances (approx ±0.025 mm). For this reason, it can be turned into different chips and shapes with ease.

During CNC machining, the alloy machines are well but not as nicely as 6061 and not as bad as 5052. So the end product of 7075 is likely to be a little more like a smooth but dull grey.

Aluminum materials have great electrical conductivity compared to other commonly used materials and alloys. For this reason, aluminum CNC machined aluminum parts are ideal for electrical uses.

In addition, it has excellent corrosion resistance, good formability and weldability, acceptable machinability, and good resistance to wear.

CNC machining aluminum produces a lot of waste that is lost in the process. It is therefore advisable to use a metal that will be recyclable.

Al5052 has excellent natural corrosion resistance. Your tools should be very sharp with excellent lubrication for better results with this brand.

Moreover, the brand offers an excellent combination of thermal and mechanical properties, which are ideal for the process. Moreover, like other aluminum alloys, it is heat treatable.

The Alu2024 has a high strength to weight ratio and it’s machinable. However, this brand is known to chip at the end of heavy cuts with the tool breaks out.

Processes such as cutting, grinding, forming, and boring require easy work with the material. However, unlike others, aluminum can be turned easily because of its thickness and strength-to-weight ratio.

Among other types of aluminum, alu6061 is the total staple for machining. It is an enjoyable metal to cut. Alu6061 is readily available in any machine shop.

It’s among the more popular aluminum alloys in its series, including alloy 6005, 6061, and 6063. Alu6082 is formed by extrusion and rolling.

Anodization is the process of using a surface finishing procedure to thicken the protective already oxidized outer layer of metal parts.

Aluminum material is highly resistant to low temperatures. Steel, which is used in place of aluminum, is quite fragile, especially if working at low temperatures.

Aluminum alloy has a thermal conductivity of 121-151/W· (m·k). The competitor metal, stainless steel, has a thermal conductivity of 58.6-41.9/W· (m·k).

The significant mechanical properties of this brand include poor formability and weldability, fine machining, and average corrosion resistance.

Moreover, due to its low friction coefficient and high corrosion resistance, brass is used for applications in engineering, plumbing, steam work, and musical instruments.

Generally, the machinability of aluminum makes work easy and shortens the working duration, making complex aluminum parts more affordable.

Aluminum can, however, be replaced by other metals that work relatively the same or slightly different. These metals include steel and stainless steel, titanium, brass, and copper.

Different grades of aluminum produce different results in the machine. Therefore, it is vital to know the grade you are working with and how it works.
