Why Aerospace Manufacturers Prefer Forgings
1.Improved Grain Flow
During forging, the metal's grain structure follows the shape of the component, improving mechanical strength and fatigue life compared to plate materials.
2.Higher Structural Integrity
Forging compresses internal voids and improves density, resulting in stronger and more reliable material performance.
3.Better Fatigue Performance
Aircraft components often experience cyclic loading. Forged materials provide superior fatigue resistance, reducing the risk of crack initiation.
4.Superior Load Distribution
Forgings perform better under complex multi-directional stresses, which are common in aerospace structures.
5.Reduced Machining Waste
Near-net-shape forging allows manufacturers to remove less material during machining, improving material utilization and cost efficiency.
Quality Control for Aluminum Forgings (EN · AMS · ASTM Standards)
1. Ultrasonic Testing (UT)
Ultrasonic testing (UT) is the most widely used nondestructive inspection method for aerospace forgings.
ASTM A388 – Ultrasonic examination of steel forgings (often referenced for general UT practice)
AMS 2631 – Ultrasonic inspection requirements for aerospace forgings
AMS 2630 – Ultrasonic inspection of aluminum alloys
2. Dye Penetrant Testing (PT)
Penetrant inspection is used to detect surface defects that cannot be seen visually.
ASTM E1417 – Liquid penetrant testing
AMS 2644 – Penetrant materials specification
3. Mechanical Property Testing
Mechanical tests confirm that forgings meet required performance specifications.
Tensile testing (ASTM E8 / ISO 6892-1)
Hardness testing
Impact testing (when required)
4. Chemical Composition Analysis
Spectrometers or chemical analysis are used to confirm alloy composition.
Typical Standards
ASTM E1251 – Aluminum alloy chemical analysis
EN 573 – Chemical composition limits
5. Dimensional & Visual Inspection
Final inspection confirms:
dimensional tolerances
surface quality
geometry compliance with engineering drawings
