Metals used in the aerospace industry must be light and strong, providing unmatched reliability despite extreme pressure, high heat and dramatic shifts in temperature. Titanium is often the material of choice for both airframes and turbine engine parts. Tungsten is used to make rocket engine nozzles. Invar® and other nickel-iron alloys are used for aircraft instrumentation and precision composite molds.
NETIC® is uniquely different from Co-NETIC®. It is an iron alloy that is often applied in fields of high intensity (strong fields) because of its high magnetic saturation characteristics. Frequently, NETIC® is used in conjunction with a layer of Co-NETIC® as layering is proven to provide extra precaution and/or lower risk of electro-magnetic interference. If used in combination, the NETIC® layer is placed closest to the source of interference, with Co-NETIC® or MuMETAL® layer closest to the component being shielded.
Co-NETIC® Or NETIC®?
In fields of low intensity, Co-NETIC® is used in order to utilize its high initial permeability and corresponding high attenuation characteristics. In strong fields of high intensity, NETIC® is preferred because of its high magnetic saturation characteristics. In some applications, combinations of the two materials may be useful, with NETIC® material always placed closer to the source of magnetic interference.
Co-NETIC® is considered far superior in shielding performance due to its consistent quality, material composition and Perfection Annealing process. A Ferromagnetic that is used primarily in low intensity fields where high attenuation is desired (high initial permeability & high shielding efficiency), it has become our leading brand. Co-NETIC® alloy is readily available from stock in three forms:
Co-NETIC® AA Perfection Annealed
Co-NETIC® Stress Annealed
Co-NETIC® B Stress Annealed
Heavy metal alloys are pseudo-alloys of tungsten with a nickel-iron or nickel-copper matrix. They are produced by powder metal and sintering processes. Tungsten Heavy Alloys has a high density of 17-19 g/cm³. Comparable densities are only reached by gold or platinum. These alloys are used as mass balancing weights and attenuators in aircraft construction, in motors and power trains, as oscillating weights and centrifugal weights in machines and in equipment construction, and in medical technology for both protection from and focusing of ionizing radiation in x-ray and measuring devices.
It is used in laminated cores for instrument transformers, magnetic shields and cores for certain electronic and communication devices. High Perm 49’s extremely high permeability at low magnetizing forces significantly increases operational effectiveness and efficiency. Because of its high permeability, it is used in solenoid cores and in light-sensitive relays that must operate and respond to weak currents that induce low magnetizing forces.
Ti-6Al-4V (UNS designation R56400), also sometimes called TC4, is an alpha-beta titanium alloy with a high strength-to-weight ratio and excellent corrosion resistance. It is one of the most commonly used titanium alloys and is applied in a wide range of applications where low density and excellent corrosion resistance are necessary such as e.g. aerospace industry and biomechanical applications (implants and prostheses).
