In this regard, 6061 is one of the most common aluminum alloys that meet a wide range of application requirements, making it among the best aluminum for machining.

Among all of the available grades of aluminum, 3003 is the most common aluminum alloy used for various general-purpose applications due to its decent strength and good workability.

6061 aluminum alloys are highly versatile, containing silicon and magnesium as major alloying elements. These different aluminum alloys display excellent corrosion resistance and a good strength-to-weight ratio, highly sought-after mechanical properties for building marine and aerospace structures.

When choosing the best aluminum for machining, considering corrosion resistance is crucial. Heat-treatable alloys, such as 6061 and 7075, offer good machinability and strength, but 3003, with its excellent formability, is preferred for applications where forming is critical.

As a cold-treated metal, 3003 aluminum alloys are also prone to hydrogen-induced porosity during welding. The best way to avoid this situation is to drop hydrogen pickup to a low level while welding. This is another major reason why 3003 cannot be used for extreme environment applications.

3003 is an aluminum-manganese copper alloy that is moderately strengthened by cold hardening. Manganese is the main alloying element in the 3003 aluminum alloys, with its percentage varying between 1% and 1.5%, depending on how the aluminum alloy is fabricated.

The uses of metal milling are widespread, ranging from creating intricate parts for machinery to crafting customized components for specific applications. Here are a few common examples:

There are two main configurations of milling machines, defined by the orientation of their cutting spindles. Both styles can handle various metal milling applications, which we’ll explore in more detail below.

In terms of formability, 3003 is a better choice over 6061, especially if the application requires good formability to meet design requirements.

Milling is a machining process that uses rotary cutters to remove material from a metal workpiece by advancing against the cutter slowly. This shapes the workpiece to precise specifications suitable for a wide range of applications.

Milling metal on a manual machine takes skill and experience. The machinist must monitor and adjust as the material is removed to achieve the desired results.

However, it has poor formability. If you need good formability from a 6061 alloy, 6061-T4 would be an ideal choice, as it is naturally aged to have good formability and excellent weldability. In short, different 6061 tempers can meet wide application requirements, unlike 3003 tempers.

The cutters are mounted horizontally on an arbor extending from the machine. This type often uses endmills and slab mills with cutting teeth on the periphery and bottom.

The presence of copper and magnesium offers 20% additional strength than 1100-grade aluminum, yet due to its low tensile and yield strengths, it is labeled as a moderately strong material.

Apart from moderate strength, 3003 aluminum alloys are corrosion resistant, workability, and weldability. Thus, it is an ideal light structure material, globally acknowledged as the most common aluminum alloy or general-use alloy. The most common applications of 3003 occur in the aerospace, food, and chemical industries.

Metal milling is a metal finishing service that removes material and shapes metal workpieces. From aerospace components to automotive parts, this versatile machining technique has many applications across industries. Keep reading as we explore everything you need to know about metal milling.

Common aluminum alloys, including those mentioned, are frequently used across various industries, showcasing the versatility and broad utility of these commonly used alloys.

Aluminium machinabilitymethods

CNC machines have revolutionized metal milling, allowing for automated, precise, and efficient machining. The integration of computer numerical control enhances accuracy and repeatability. The computer automates movement, allowing for faster, more repeatable production runs.

For instance, 6061-T6 aluminum alloys are solution heat-treated and artificially aged to offer good machinability and excellent weldability.

6061 aluminum alloys are heat-treated and thus are available in different tempers, such as F, O, W, and T. In this regard, the 6061-Tx variant has many applications. In 6061-Tx, the letter “T” represents temper, and “x”, usually represented as a digit, indicates whether the alloy has received any special treatment.

We not only supply new metals sourced straight from U.S. mills, but we also offer verified metal remnants, recycled from the production lines of manufacturers that have no further use for the scrap.

They also are not heat-treatable alloys, which means, unlike heat-treated metals, they cannot achieve a secondary phase of precipitation hardening required for improved strength.

Despite all of these advantages, machining 3003 can prove challenging. Though 3003 tempers have fair machinability, they are less machinable than other harder aluminum alloys.

Industrial Metal Service has been supplying metals, including aluminum alloys to the San Francisco Bay Area and nationwide for more than two decades. Our extensive collection of aluminum stock includes 6061, 3003, 7075, 5080, MIC-6, and more.

It’s important to know which variant is best when machining aluminum. Below, we detail the wide range of mechanical properties of 3003 and 6061 aluminum and discuss the applications in which each alloy excels.

Here, the cutters are secured vertically in the spindle nose, with endmills and slot drills being the most common tooling options.The machine style ultimately depends on the complexity and specifications of the workpiece. Multi-axis CNC milling utilizes computer programming for optimal precision. By integrating software with the mechanical mill, manufacturers achieve tighter tolerances, faster cycle times, and the flexibility to adapt as needed.

For example, 3003 is an excellent choice for outdoor decorative architecture that requires formability and moderate strength for a good aesthetic appeal. However, as a cold-treated alloy, it is unsuitable for structural applications requiring heavy machining.

However, when it comes to strength, 6061, another commonly used aluminum alloy, triumphs over 3003 with more yield strength, which is useful for designing structural applications.

Not all aluminum alloys are created equal. Most aluminum production is intended for structural applications, such as body frames and parts, in the automobile and aerospace industries to improve the strength-to-weight ratio.

With good electrical and thermal conductivity, 6061 plates also find broad applications in electrical fittings, connectors, and magneto parts.

With manganese as the primary alloying element, 3003 scores excellent in terms of formability and corrosion resistance as compared to other aluminum metals and tempers.
