An alloy with exceptional damping properties exported to the planet Mars!
tg φ ∼ 1,80.10-2 (soit 2π sin φ ≈ 11,30.10-2)
Below -30°C and above +60°C, its damping properties are similar to those of grey iron.
But between -15°C and +50°C, this materiel is 10 times better than lamellar graphite grey iron!
This alloy can be spun cast in classical centrifugal form or even plates or discs.
EXIUM® AM can be used for
Remember: vibration reduction = noise reduction
EXIUM® AM was selected for the InSight mission. The two pieces in the seismometer SEIS are 12mm in diameter for 20mm long and this material is used as a high frequency vibration damper.
The centrifugal casting process (or spun casting) is mainly suitable for cylindrical or hollow pieces (rings, tubes etc…). Conical shapes, several different diameters or flange(s) can be obtained on the “as cast” outer profile.
As we do not use cores, the inside diameter is cylindrical and is achieved by the quantity of liquid metal poured into the tooling.
Our extensive range of toolings (more than 1500 dies) enables us to reach the ideal cast sizes and shapes, consequently to propose the most economical solutions.
