Get An Instant QuoteAluminum is a lightweight metal known for its excellent strength-to-weight ratio, making it ideal for applications that require robust metal performance without added weight. Aluminum is available in a variety of alloys, each identified by a classification number where the first digit indicates the primary alloying element. Below is a classification of aluminum materials.
1 series aluminum content exceeds 99.00%, with good conductivity, corrosion resistance and welding performance; but the strength is low and cannot be strengthened by heat treatment. High-purity aluminum (aluminum content exceeds 99.9%) is mainly used in scientific experiments, chemical industry and special purposes.
Aluminum alloy with copper as the main alloying element, also adds manganese, magnesium, lead, bismuth and other elements to enhance cutting processability. 2011 alloy, pay attention to safety protection during smelting (dangerous gases will be generated). 2014 alloy is used in the aviation industry and has high strength. 2017 alloy is lower in strength than 2014 alloy, but is easier to process, and 2014 alloy can be strengthened by heat treatment. Commonly used Aviation industry (2014 alloy), screws (2011 alloy), industries with high operating temperatures (2017 alloy).
Aluminum alloys with manganese as the main alloying element cannot be strengthened by heat treatment. They have good corrosion resistance and welding performance, and their plasticity is close to that of super aluminum alloys. They are used for oil-conducting seamless pipes (alloy 3003) and tanks (alloy 3004) for aircraft.
The main component of 4 series aluminum profiles is silicon, and some can be strengthened by heat treatment. 4032 has good heat resistance and friction resistance, and a small thermal expansion coefficient. It is often used in pistons, cylinder heads, etc. 4043 has a small solidification shrinkage. After sulfuric acid anodizing, it naturally develops a gray color. It is often used for welding lines, building panels, etc.
5 series aluminum profiles are mainly magnesium, with good heat resistance, welding performance, and fatigue strength, but cannot be strengthened by heat treatment, and can only be improved by cold working. They are often used in lawn mower handles, aircraft fuel tank ducts, bulletproof vests, etc. 5005
The strength is the same as 3003, with good processability, weldability, and corrosion resistance. It has good finishing properties after anodizing, and the color is consistent with 6063 profiles. 5052 is the most representative alloy, with medium strength, good corrosion resistance, weldability, and formability, especially high fatigue strength and good seawater resistance. It is generally suitable for sheet metal, ships, vehicles, buildings, bottle caps, honeycomb panels, etc.
Generally, mid-range and above aluminum materials are basically 6 series. Aluminum-magnesium-silicon alloy is composed of three metals: aluminum, magnesium, and silicon. A composite material composed of 2,4-dioxide and 2,6-dioxide, is the most widely used alloy at present. Among them, 6063 and 6061 are the most commonly used, followed by 6082, 6160, 6125, 6262, 6060, 6005 and 6463; 6063, 6060 and 6463 have relatively low strength in the 6 series. 6061 has medium strength, good corrosion resistance, good welding performance, good process performance (easy to extrude) and good oxidation coloring performance.
7072 has a low electrode potential and is mainly used for anti-corrosion covering skins and is also suitable for heat exchanger fins. 7075 is one of the strongest alloys in aluminum alloys, but has poor corrosion resistance. 7075 is a hardenable alloy with good resistance to stress corrosion cracking, suitable for thick plates, forgings, aircraft, high-speed rotating bodies, etc.

CNC machined aluminum enables the production of diverse components and assemblies that support a wide range of industrial applications. Today, high-precision CNC aluminum parts are increasingly essential across engineering fields. We provide the following types of CNC machined aluminum parts to meet our customers' needs:
CNC machining is applicable to materials with sufficient hardness for milling, including plastics, metals, and composites. Aluminum, as a lightweight metal, offers an exceptional strength-to-weight ratio, making it an ideal choice for applications requiring robust performance without added weight. Aluminum is available in numerous alloy types, each classified by a numbering system where the first digit indicates the primary alloying element.
The inherent hardness of aluminum makes it highly suitable for producing mechanical parts via CNC machining, while its natural oxide layer provides reliable protection against corrosion. Aluminum possesses multiple properties that contribute to efficient and convenient CNC machining. Compared to many metals with similar traits, aluminum demonstrates superior machinability — most grades allow smooth cutting, easy chip formation, and effortless shaping with standard tooling. This high machinability enables faster processing speeds, reducing both machining time and labor costs on CNC equipment. Additionally, it supports the attainment of tighter precision tolerances, essential for manufacturing high-accuracy components.
Slinar delivers meticulous solutions and custom aluminum parts manufactured precisely to your specifications and requirements. We handle both large and small production batches, along with one-off projects including new product development and R&D initiatives.

Committed to accelerating your development cycle and reducing costs, Slinar is your trusted partner whether for single prototypes or full-scale production runs of thousands of units.
Most CNC machining shops only quote CNC machining as a stand-alone operation. But when new parts are in the hundreds or more, you need a more complete solution to achieve the best results. Some of these parts are better not milled from a solid block, but die-based machining or milling-assisted forging processes. Extrusion, casting and forging processes can all be combined with CNC machining to create better aluminum parts. Whatever the test conditions, whatever the performance requirements.
We are committed to supporting our customers’ manufacturing requirements, including producing specialized parts that are often difficult to source elsewhere.
