Why Aluminum is Widely Used in Aerospace Metal Spinning

Aluminum alloys are the most commonly used materials in aerospace spinning due to their unique balance of mechanical and physical properties:

• High strength-to-weight ratio
• Excellent corrosion resistance
• Superior formability for thin-wall parts
• Good thermal and electrical conductivity

Typical alloys:

• 5A02 / 5052 (corrosion-resistant structures)
• 6061-T6 (structural strength applications)
• 7075 / 2A12 (high-strength aerospace components)

👉 Engineering Insight:
Aluminum enables weight reduction of up to 60–70% compared to steel, while maintaining structural integrity.

What Tolerances Can Be Achieved in Aerospace Metal Spinning?

Precision control is critical in aerospace applications.

At KMS, we achieve:

• Linear tolerance: ±0.1 mm (GB/T 1804-m)
• Geometric tolerance: GD&T control per GB/T 1184-K
• Concentricity & coaxiality: ≤ 0.1 mm
• Critical interfaces: 100% inspection

👉 Key Advantage:
Metal spinning allows stable repeatability in thin-wall cylindrical and conical parts, where machining may introduce deformation.

How to Prevent Deformation in Thin-Wall Aerospace Parts

Thin-wall deformation is one of the most common challenges in aerospace manufacturing.

Root Causes:

• Material springback
• Uneven stress distribution
• Excessive forming force

Our Solutions:

• Multi-pass progressive spinning
• Toolpath optimization
• Controlled thinning (flow forming)
• Dedicated tooling for complex curvature

👉 Result:
Stable geometry with minimal distortion, even in large-diameter thin-wall parts.
