At City Special Metals, we stock high quality aerospace alloys and are accredited to AS9120 B, the Aerospace Requirements for Stockist and Distributors. This standard includes ISO 9001:2008 quality management system, so you can rely on us for critical aerospace components.
From exhaust systems to springs and fasteners, landing gear to turbine blades, discs and rings, specialty alloys are the number one choice for aerospace mechanisms. With experience and knowledge of the metals industry, our team know which alloys are the best for aerospace application.
Alloy Properties for Aerospace
As there are so many different components and mechanisms that make up both the external and internal structures of aerospace bodies, the properties vary for different parts. As consensus, the alloys generally used across the board should be durable and strong, yet lightweight.
The ability to withstand extreme temperatures is required for parts such as turbine engines and exhausts. In addition to consistent high quality, it is important for the alloy to be supplied in multiple product forms so it can cater to the specific application.
Specific Alloys for Aerospace
Copper-based alloys display high strength, flexibility and corrosion resistance so they are commonly used for number of external aerospace components. As copper is flexible and easy to machine, it can be moulded into structural pieces; with added strength and resistance to corrosion, copper construction can be relied upon for the long-term duration.
One of the most popular alloys used in the aerospace sector is aluminium due to its low density and high strength properties. Also corrosion-resistant, aluminium can be strengthened to your specifications and is usually used for the majority of the aircraft structure.
Titanium is incredibly popular and used for a number of different aerospace components including the exterior structure and internal engine and wing parts. Both high strength and high corrosion resistance mean titanium is durable, and with high temperature resistance as well, it is completely versatile and suitable for the majority of mechanisms.
With the ability to retain their strength and shape without deformation at extreme temperatures, nickel alloys are ideal for the immense heat exposure within the engine. Exhaust valves, thermostat rods and tanks and piping for liquified gas storage are also exposed to high heat, which means the aerospace industry are major end-users of nickel.
