Technical Specifications of In-Stock 2A70 Aerospace Round Bars

We supply only certified, solid circular profiles whose internal grain matrix is perfectly optimized for subsequent complex turning, boring, and CNC milling operations:

• In-Stock Diameter Range: From 150 mm up to 250 mm.
• Standard Stock Bar Length: 3000 mm (precision custom-size band saw cutting into specific blank lengths is available).
• Alloy Grade: 2A70 (a high-performance, heat-resistant forging alloy belonging to the Al-Cu-Mg-Fe-Ni system).
• Processing Profile: The material is heat-treatable (solution heat-treated and artificially aged) to achieve peak physical-mechanical properties and maximum hardness.

Material Characteristics and Engineering Advantages of Alloy 2A70

Aluminum alloy 2A70 represents a complex multi-component metallurgical system precisely alloyed with copper, magnesium, iron, and nickel. The specific addition of nickel and iron triggers the formation of stable intermetallic phases that actively prevent the structural softening of the aluminum matrix during heating. This chemical trait makes 2A70 round bars significantly more efficient under continuous thermal stress compared to standard 2A80 alloys or traditional duralumin like D16 (2024).

Key Engineering Benefits of 2A70 Round Bars:

• Extreme Heat Resistance: The continuous working temperature range for finished parts machined from this alloy is 200°C to 250°C. The metal retains its dimensional stability, exceptional ultimate tensile strength, and structural rigidity under prolonged thermal exposure.
• High Hot Ductility: The complete absence of deformation lag effects allows engineers to forge, stamp, and shape the bar into intricate custom components via hot forming methods.
• Superb Machinability: Bars with diameters of 150–250 mm are perfectly optimized for heavy-duty coordinate milling, precision turning, and drilling on modern CNC machine centers. The material yields an impeccably clean, mirror-smooth finished surface.
• Welding Characteristics: Classified as a medium-weldable grade. The alloy is optimally suited for electrical resistance spot welding and seam welding, allowing for reliable integration into complex assemblies (gas and arc welding methods are less effective).
• Classic Aluminum Traits: While delivering steel-like structural endurance, the raw material remains lightweight, highly resistant to atmospheric corrosion, sudden temperature swings, and corrosive environments. It guarantees an extended operational lifespan and remains highly straightforward to install.
