Aluminum profiles, often referred to as aluminum extrusions, are categorized into 8 series based on the numbering system of aluminum and its alloy. This classification helps in indentifying the properties and suitable applications for each type of aluminum profiles.
Series 1: Pure Aluminum
The pure aluminum series boasts a purity of over 99%, offering the highest aluminum content among all series. This results in excellent aluminum extrusion quality and makes it highly amenable to surface treatments. Pure aluminum has the best corrosion resistance among aluminum alloys, although it is relatively soft. Consequently, it is primarily used for decorative and interior parts where high strength is not required but appearance and resistance to oxidation are cruial.
Series 2: Aviation Aluminum
The second series, often referred to as aviation aluminum, is characterized by its high hardness and significant copper content (3-5%). These aluminum profiles are not commonly used in ordinary industries due to their specialized applications in structural materials for aviation. Examples include alloys 2024, 2A16 and 2A02, which are known for their strength and durability in demanding environments.
Series 3: Good Formability and Corrosion Resistance
The third series aluminum profiles are known for their excellent formability, fusion, and corrosion resistance. They are typically used for manufacturing tanks and containers for liquid products, construction parts, tools, lighting components, and various pressure vessels and piplelines used in sheet metal processing.
Series 4: Construction and Mechanical Parts
Aluminum extrusions from the fourth series are commonly utilized in construction materials, mechanical parts, forging materials, and welding materials. This series is noted for its low melting point, good corrosion resistance, heat resistance, and wear resistance. It also offers good fluidity when molten and minimal solidification shrinkage. A notable example is the 4A01 aluminum rod.
Series 5: Aluminum-Magnesium Alloys
Five series aluminum profiles are among the most commonly used aluminum alloys, with magesium content ranging from 3% to 5%. These alloys are known for their low density, high tensile strength, and high ductility. Aluminum-magnesium alloys are lighter than other series when compared by area. Notable representatives include 5052, 5005, 5083 and 5A05.
Series 6: Magnesium and Silicon Alloys
The sixth series combines magnesium and silicon, offering the benefits of both the fourth and fifth series. These aluminum profiles feature excellent corrosion resistance, good oxidation resistance, and are easy to coat, making them particularly suited for processing. The 6061 and 6063 series are prominent examples, with 6061 being widely used in mobile phone frames and 6063 in doors and windows. The high strength of 6061 makes it ideal for casting complex structures, such as battery covers for mobile phones.
Series 7: High-Strength Zinc Alloys
The seven series primarily includes zinc along with magnesium and copper, forming an aluminum-magnesium-zinc-copper alloy that can be heat-treated to acheive super-hard properties. These aluminum extrusions are wear-resistant and are commonly used in aviation materials and mold materials. The 7075 series is a key representative, though production technology in China is still developing, and reliance on imports is prevalent.
Series 8: Other Applications
The eight series aluminum alloy, primarily represented by 8011, belongs to other series and is mainly used for aluminum foil production. It is not commonly used for manufacturing aluminum rods.
Why choose 6063 for broken bridge doors and windows?
When selecting aluminum profiles for broken bridge doors and windows, the choice often falls on the 6063 series. Here's why:
Hardness and Strength
Aluminum profiles can be classified by hardness in descending order: 7075, 2024, 6063, 5052 and 3003. For applications requiring high strength, the 7 and 2 series are preferred due to their classification as super-hard aluminum alloys. The 7, 2 and 6 series are suitable for cutting, whereas the 3 and 5 series are best for stamping.
Anodic Oxide Film Transparency
From the perspective of anodic oxide film transparency, the order is 5, 6, 3, 2 and 7. The 6 series offers significant advantages in corrosion resistance under high-temperature conditions, such as in fires, compared to the 2 and 7 series.
Processing and Anodic Oxide Film Protection
Doors and windows require a balance of hardness, processability, and anodic oxide film protection. The 6063 aluminum profile meets these requirements, making it ideal choice for manufacturing broken bridge doors and windows. The 6063 series combines excellent processing performance with sufficient strength and superior corrosion resistance, ensuring durability and aesthetic appeal.
Into its balanced properties. Its good oxidation resistance, ease of coating, and optimal strength make it suitable for complex structural components. Additionally, it provides excellent thermal insulation, which is crucial for energy-efficient window systems.
