APPLICATION SPOTLIGHT

Fasteners

Airframe Fasteners
Airframe Fasteners

Fasteners add weight. On aircraft, the strength to weight ratio is critical. Meanwhile, quality is essential in no-fail situations that include temperature extremes, high pressures, stress and weight loads, and corrosion.

Torsion Springs
Torsion Springs

Springs store mechanical energy as they are twisted. Their materials must be high strength with extremely good fatigue resistance to ensure they do not break under repeated loads.

Fluid Connectors

Aerospace Fastener: FAQs

What materials are typically used for aerospace fasteners?

Aerospace fasteners are commonly made from high-strength steels, titanium alloys, and nickel-based alloys, selected for their ability to maintain strength, resist corrosion, and perform under cyclic loading.

How do materials affect fastener preload and joint integrity?

Material properties influence how well a fastener maintains clamp load over time. Strength, elasticity, and resistance to relaxation all contribute to long-term joint stability.

Why is fatigue resistance critical for aerospace fasteners?

Fasteners experience repeated loading and vibration during operation. Materials must resist crack initiation and propagation to prevent loosening or failure.

How do environmental conditions impact aerospace fastener materials?

Exposure to moisture, temperature changes, and corrosive elements can degrade fasteners. Materials must be selected to maintain integrity in these environments.

Can Carpenter Technology support material selection for specific fastener applications?

Yes. Our metallurgists work with engineers to recommend alloys that align with strength, fatigue, corrosion, and manufacturability requirements.
