| Aluminum Alloy 6061-T6 | DIN EN 3.3211 | UNS A96061 | AlMg1SiCu | In terms of its strength-to-weight ratio, machinability, and resistance to corrosion, nothing beats the aluminum 6061 (CNC) among other aluminum alloys. This material does not stick to magnets and can hardly be eroded by rust. |
| Aluminum 7075-T6 Alloy | DIN 3.4365 | Lightweight & High Strength | AlZn5.5MgCu | 7075-T6 aluminum, a first-class aerospace material, is characterized by an impressive strength-to-weight ratio equal to that of steel. This CNC aluminum is not magnetic and, therefore, can be used for different purposes. |
| Aluminum Alloy 6063 | EN AW-6063 | 62400 | AlMg0.7Si. | Aerospace applications are why aluminum 6063 is said to have excellent mechanical properties and be heat treatable. Besides, it can also be welded. This metal is adaptable and has many applications in different fields.Decorative anodizing. |
| Aluminum Alloy 5052 (EN AW-5052) - AlMg2.5 - Grade 3.3523 | The amazing thing about Aluminum 5052 is that it’s a top-notch, high-strength aluminum alloy with excellent corrosion resistance. It can be used for marine applications because of this property among others. Being highly versatile in nature, the material also allows for welding which gives it strength and durability needed in different areas. |
| Aluminum Alloy 2024-T351 | ASTM B209 | High Strength | Aerospace Grade | The aluminum 2024 is a highly potent compound famous for its outstanding fatigue resistance, which makes it suitable for aerospace uses. This material is very tough and works well in harsh conditions. |
| Aluminum Alloy 6082-T651 | Grade 3.2315 | UNS A964430 | Aluminium Silicon Magnesium Manganese | Closely composed and having almost the same characteristics as 6061 aluminum, Aluminum 6082-T651 (CNC) however has a bit higher tensile strength than the former. It is British Standards compliant which makes it widely used in the metalworking sector because of its reliability. |

Finishing Options for CNC Machining
From improved corrosion resistance to refined aesthetics, surface finishes are essential for CNC machined parts. We offer a variety of finishing options—such as anodizing, powder coating, polishing, and electrophoretic coating—each tailored to enhance durability, function, or appearance depending on your application needs.
Anodizing
Electrochemically forms a dense aluminum oxide layer on the surface to enhance corrosion and wear resistance. It can be dyed in various colors such as black, gold, red, and clear.
Electrophoretic Coating
Applies a uniform paint film through an electric field to improve surface corrosion resistance and visual appeal. The result is smooth, even, and protective.
Powder Coating
A dry powder is electrostatically sprayed onto the surface and then cured at high temperature, forming a durable, weather-resistant finish available in a variety of colors.
Polishing
Mechanical or chemical processes remove oxidation and micro-defects to produce a smooth, mirror-like surface—ideal for decorative and functional parts.
Sandblasting
High-speed abrasive particles are blasted onto the surface to remove oxide layers and residues, increase roughness, and enhance adhesion for subsequent coatings.
Brushing
Creates fine, directional textures using abrasive belts or brushes to achieve a matte, decorative finish with a consistent grain pattern.
Electroplating
Deposits a thin layer of metals like nickel, chrome, or copper on the aluminum surface to improve corrosion resistance, wear performance, or achieve a distinct appearance.
Laser Engraving
Uses precise laser technology to mark logos, text, or patterns on the aluminum surface—offering permanent, high-contrast, and aesthetic results.

FAQs About CNC Aluminum Machining
What Aluminum Grades Are Commonly Used in CNC Machining?
Grades like 5052, 6061, 7075, and 2024 are widely used due to their balance of strength, machinability, and corrosion resistance. The choice depends on application needs such as structural load or surface finish.
Can Machined Aluminum Parts Be Anodized?
Yes, anodizing is a common surface treatment for aluminum parts after machining. It enhances corrosion resistance, allows coloring, and improves surface durability.Machmaster has its own anodizing workshop, ensuring better quality control.
How Does Aluminum Grade Affect Machinability and Cost?
Higher-strength grades like 7075 offer better performance but can be harder to machine and more costly than 6061. Material selection should match both functional and budget priorities.
What Should I Consider About Cost in CNC Aluminum Projects?
Costs depend on material grade, part geometry, tolerance, surface finish, and volume. Simple parts in 6061 cost less than complex parts in 7075 with tight tolerances.
What’s the Difference Between Machining 6061 and 7075 Aluminum?
6061 is easier to machine and anodize, while 7075 provides superior strength and wear resistance. Each suits different end-use scenarios—from general parts to aerospace applications.
