Carpenter Technology delivers high-performance alloys that transform what modern rotorcraft are able to achieve, from high-torque rotor shafts to precision-engineered fasteners. With decades of materials leadership and deep application expertise, we help defense and aerospace manufacturers design faster, stronger, and more reliable aircraft that ensure mission success in the most hostile environments.
High strength and toughness are imperative for the structural alloys used in this critical design component. We offer alloys with the highest core strength and fatigue resistance to ensure peak performance under extreme rotational stress.
Premium quality high-strength carburizing steel with ultra-high core strength and temperature resistance.
Low alloy, nickel-chromium-molybdenum steel heat-treated for a superior combination of ductility and toughness.
Bushing and motor applications require exceptional reliability throughout rapid changes in temperature, pressure, and environment. Our materials are designed to withstand heavy loads and corrosive exposure without compromising integrity.
Engineered for good ductility with excellent corrosion and wear resistance in high-stress environments.
Subjected to salt spray and high torque, materials on marine and naval helicopters demand the highest levels of readiness. We customize material properties to specific applications, delivering high-strength stainless solutions for corrosive environments.
Best-in-class high-strength stainless steel designed for improved notch tensile strength and resistance to stress corrosion cracking.
Strength, toughness, and fatigue performance are critical for helicopter gear components that allow them to run at high load levels without failure. Our materials ensure exceptional performance and "oil-out" reliability in extreme conditions.
Carburizable alloy for superior wear resistance and improved oil-out performance.
High core strength and case hardness for improved wear resistance and power density.
High carbon steel optimized for wear resistance and fatigue performance in high-speed bearings.
In rotorcraft, the strength-to-weight ratio is critical to weight management and fuel efficiency. Our materials are designed for no-fail situations involving temperature extremes, high pressures, and vibration-induced stress.
Ultra-high tensile strength and toughness with excellent corrosion resistance derived from cold working.
Stronger, more consistent components built for long-term structural stability.
Predictable processes that reduce rework and shorten production timelines for defense contracts.
Capabilities for intricate gear teeth, specialized splines, and miniaturized flight systems.
Clean, reliable components engineered for safe performance in "hot and high" or maritime conditions.
