Maintains integrity under the high thermal demands of gear operation.
Supports load-bearing capability across structural joints.
Handles repeated stress without loss of integrity.
Maintains performance in harsh atmospheric and operational conditions.
Reduces risk of brittle failure under load.
Minimizes defects that can initiate cracks in service.
Aerospace fastener performance depends on a precise balance of mechanical and environmental properties.
Driving ongoing fastener innovation to meet evolving aerospace fastening requirements.
Manufacturing and testing processes designed for consistency and traceability.
Work directly with metallurgists to align material selection with application demands.
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.
A fully heat treatable workhorse alloy performing at temperatures up to 650°F (350°C) offering strength with light weight and corrosion resistance
Provides greater processing efficiency compared to other materials, reducing scrap waste by 20% or more
A precipitation hardenable nickel-base alloy with exceptionally high yield, tensile, and creep-rupture properties at temperatures up to 1300°F (704°C) for fatigue resistance
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.
Unique combination of ultra-high tensile strength, good ductility and toughness, with excellent corrosion resistance
Consistent dimensions of material allow the designer to use repetitive settings for machining devices, reducing adjustment and pre-machining time - maximizing throughput
