Other aerospace materials
We stock a wide range of other materials including aluminum bronze, nickel and copper alloys, in specifications that are applicable to most of the current aerospace manufacturing programs.
Both national and aircraft manufacturers’ proprietary specifications are stocked in a broad selection of types and sizes. We can also accommodate special requirements as a result of our close ties to the leading mills, so all stock items can be cut to size and machined precisely to your specifications.
Aluminum bronze : high-performance alloys for diverse applications
Aluminum bronzes are principally alloys of copper and aluminum. In addition to aluminum, which ranges from 5%-to-14%, other commonly used alloying elements are nickel, iron, manganese, silicon and tin.
Three principal types of aluminum bronzes are available:
Low alloy, single-phase alpha alloys contain less than 8% aluminum, have good ductility, and are well suited for cold working into tubes, sheets and wires.
Two-phase, or duplex alloys, contain 8%-to-11% aluminum and are usually alloyed with iron and nickel to achieve higher strength. The increased aluminum content causes the appearance of the relatively harder beta phase, resulting in higher strength and hardness.
Copper-aluminum-silicon alloys, consisting of roughly 6% aluminum and up to 2% silicon, are called silicon-aluminum bronzes. Originally developed for the manufacture of propellers, these alloys feature improved foundry and application properties, and have especially good resistance to impact and cavitation.x

Nickel alloys: superior performance in extreme conditions
In conditions where the corrosion and heat resistance of steels and other metals are exhausted, high-performance alloys that include nickel are the material of choice.
In aero engines, the combination of titanium alloys for the cooler compressor areas, and nickel superalloys for the hot gas path in the turbine, enable an optimal weight and performance ratio.
The strength characteristics and corrosion resistance of nickel alloys means they can be used for structural areas and for fasteners in fuselage applications.
The low thermal expansion features of nickel alloys means they can even be used in composite mould tooling.
For these, and a large variety of other applications, thyssenkrupp Aerospace offers a comprehensive range of materials to meet every need.

Copper alloys; essential materials for specialized applicationsCopper alloys
Copper is one of the oldest metallic materials in common use. With a density from 8.90 to 8.96 g/cm³ it is a relatively heavy metal with very good thermal and electrical conductivity properties. Although its weight and low strength characteristics preclude it from being widely used in aerospace products, it is still an important element in the design of electrical systems, transformer and heat exchanger applications.
Although its use is limited there are a number of different copper alloys which have been developed for aerospace use. These can be categorized into three groups: bronze (copper with tin), brass (copper with zinc) and cupronickel (copper with zinc and nickel).
As a flexible metal, copper can be deformed easily and has a very good ductility. It also demonstrates good corrosion resistance.
