Aerospace Aluminum refers to special aluminum alloys characterized by high strength, low weight, and excellent corrosion resistance. These alloys are widely used in the aerospace and aviation industries, where the focus is on combining strength with low weight. Due to its properties, aerospace aluminum is also utilized in other industries, including airsoft, where it is used to manufacture the most durable components and even entire gun bodies (such as those from Retro Arms). The most commonly used parts are CNC gearboxes, designed to withstand extreme stress. You can purchase the highest quality CNC internal parts and gearboxes on our e-shop.

Types of Aerospace Aluminum:

Aerospace aluminum alloys are categorized based on their composition and properties into different series. The most commonly used are 6000 and 7000 series alloys, with the most well-known being:

• 7075-T6:
  - The strongest and most durable aluminum alloy commonly used in the aerospace industry.
  - Contains zinc as the primary alloying element, providing extreme strength while maintaining low weight.
  - Heat-treated to **T6** for increased mechanical resistance.
  - Used in aviation, airsoft components (hop-up chambers, outer barrels), firearms (upper and lower AR-15 receivers), bicycle frames, and motorsports.
  
  
• 6061-T6:
  - Slightly less strong than 7075 but still very durable and easier to machine.
  - Contains **magnesium and silicon**, providing excellent corrosion resistance.
  - Commonly used in aircraft structures, drones, mountain bike frames, and components requiring resistance to environmental conditions.
  
  
• 2024-T3:
  - High strength but lower corrosion resistance.
  - Contains **copper**, making it stronger than 6061 but requiring additional oxidation protection (e.g., anodizing).
  - Used in aircraft structures, military equipment, and some firearm applications.
  
  
• 5052:
  - Very corrosion-resistant but less strong than 7075 and 6061.
  - Suitable for marine applications, fuel tanks, and structures exposed to moisture.
  
  

Comparison of Main Types:

Advantages of Aerospace Aluminum:

• High strength-to-weight ratio.
• Resistance to mechanical stress.
• Can be anodized for surface protection.
• Good thermal conductivity.

Disadvantages of Aerospace Aluminum:

• Higher cost compared to standard aluminum alloys.
• Some types (e.g., 2024) have lower corrosion resistance.
• 7075 is more difficult to machine than 6061.
