Createproto CNC aluminum machining services provide you all-around care that our team will analyze your project carefully and process it with the most efficient process of machined aluminum to optimize your time and cost.

For CNC machining projects, aluminum is one of the most popular material choices due to its desirable physical properties. It is strong, which makes it ideal for mechanical parts, and its oxidized outer layer is resistant to corrosion from the elements. These benefits have made aluminum parts common across all industries, though they are particularly favored in the automotive, aerospace, healthcare and consumer electronics spheres.

If you are seeking a vendor to provide you high quality aluminum parts CNC machined, Createproto is one of the most capable and affordable sources specializing in manufacturing precision machined parts on advanced 3-axis and 5-axis CNC machines.

Material Finish

Untreated aluminum generally has a dull silver/grey finish which varies depending on the roughness of the surface.

Many consumer products made with aluminum are anodized, most notably the MacBook Pro. Anodization allows the introduction of a variety of color options and adds a consistent shine across the entire part.

Aluminum can also be media-blasted, sanded, and hand-polished to achieve a multitude of surface finishes. Alodine is often used as an alternative protective coating to anodize on aluminum parts, and can be clear or gold in color.

About the material

Aluminum is one of the most commonly used metals in the world because of its excellent strength-to-weight ratio, low cost, and recyclability. Fictiv offers multiple aluminum alloys.

7075 Aluminum is a hard, high strength alternative to 6061 Aluminum . It is often used for parts in high-stress applications, and is also corrosion-resistant, non-magnetic and heat treatable.

7050 Aluminum can be used instead of 7075 when high stress corrosion resistance is necessary (ie. bulkheads and fuselage frames). It is heat treatable and non-magnetic.

2024 Aluminum is not as strong as 7075 Aluminum but is commonly used when a high strength-to-weight ratio is required. It is heat treatable and non-magnetic.

5052 Aluminum is the easiest aluminum to weld and is exceptionally corrosion resistant against salt spray and salt water. It is easy to form, heat treatable, and non-magnetic.

6063 Aluminum is more corrosion resistant and formable than 6061 Aluminum. It is not ideal for high strength applications, but can be used for exterior railings and decorative trim. It is heat treatable and non-magnetic.
