The Bionic Partition is not only a new designed component for an A320. It also combines latest material and production trends with the most sophisticated design and optimization technologies to create a new baseline technology for the aviation industry. This new baseline technology will create a major impact on new generations of aircraft cabin components that are more valuable, lighter, and thus create less impact on the environment.

Elongation: >25% RT-760°C

The next generation of aeronautic engines aims at continuously improving performances and effciency, reducing at the same time emissions. However, increasing this temperature severely stresses the turbine constitutive materials. Current casing constitutive materials are designed to work at ca. 650°C and superalloys like Inconel 718 or Waspaloy are typically used. Different aeronautic propulsion producers have different strategies to develop more effcient turbines, but they are all trying to fnd materials and manufacturing routes capable to provide casings which can readily operate at 700 to 800°C.


2C Pin

Company: Schunk Sintermetalltechnik GmbH

End Use Sector: Automotive
Product Density: >7.6 / >8.2
Tensile Strength: >500 / >1000
Yield Strength: >200 / >900
Product Hardness: >120 / >440
Elongation: >50 / >2

2C-Pin is the frst serial part worldwide produced by Metal Injection Moulding of two different materials. A customer problem was solved: combination of wear resistance in a wide range of temperature and weldability of materials in one complex part. The innovation was to modify the two alloys to get nearly the same sintering behavior. Cracks are fully avoided and between the two components a continuous gradient in chemical composition instead of an abrupt joining zone can be determined. Schunk opend a new area for PM business with big growing potential.

Planetary Carrier PMSP

Planetary Carrier

Company: Stackpole International

Product Density: Spider: 7.0g/cm³, Guide Plate: 7.5g/cm³
Tensile Strength: Spider: 510MPa, Guide Plate: 730MPa
Yield Strength: Spider: 420MPa, Guide Plate: 520MPa
Product Hardness: Spider: 80HRB, Guide Plate: 90HRB
Elongation: Spider: 1%, Guide Plate: 3%

Planetary Carrier 4 is an excellent example for design collaboration between teams with expertise in powder metal process and automotive transmission design. ZF and Stackpole technical teams defned the engineering properties required for this application through joint reviews of initial bench test results and shortened the development cycle through successful simultaneous development. Stackpole International, although did not have design responsibility, undertook the bench testing and established better options for material selection.
