GR.1 The core application of ultra-thin titanium foil focuses on extreme lightness, high purity, excellent ductility/flexibility, corrosion resistance, biocompatibility, and good vacuum/conductive/thermal properties. Different ultra-thin thicknesses (in the μm range) precisely match the refined and high-demand scenarios in various fields. The core applications are concentrated in six high-value-added areas: electronic semiconductors, medical devices, high-end acoustics, aerospace, new energy, and precision vacuum equipment. These are currently the most mainstream commercialization directions for this material. The following are the specific application scenarios, suitable thicknesses, and core application advantages for each field (all are mass production/mature applications, without laboratory conceptual applications).
This is the maximum application scenario for GR.1 ultra-thin titanium foil with the thinnest specification (≤ 0.01mm). Relying on its high purity without impurities, good vacuum stability, thinness and certain structural strength, it meets the precision and miniaturization requirements of semiconductor/electronic devices.
Titanium window for electron accelerator: It is suitable for a thickness range of 0.006 to 0.01mm. It is the core component for the emission of electron beams in the accelerator. The ultra-thinness ensures high penetration rate of the electron beams, high purity avoids interference from impurities to the beam flow, and the radiation resistance and vacuum corrosion resistance of titanium are suitable for the extreme working environment of the accelerator.
Semiconductor vacuum equipment components such as vacuum chamber sealing gaskets and precise wafer transfer carrier components, with an adaptable thickness ranging from 0.008 to 0.02mm, significantly enhance the vacuum sealing and adhesion degree, and ensure high purity to prevent impurities from volatilizing and polluting the wafer. They also have flexibility to adapt to the irregular sealing surfaces of precise chambers. Flexible electronic electrodes / collectors such as flexible circuit boards (FPC) auxiliary electrodes and micro capacitor electrodes, with an adaptable thickness ranging from 0.005 to 0.015mm, significantly reduce the overall thickness of the device, and have excellent conductivity (with the best conductivity performance of industrial pure titanium, GR.1) + resistance to electrolyte / humidity corrosion, suitable for the bending and miniaturization requirements of flexible electronics; Sensor sensitive elements such as elastic diaphragms for pressure / temperature micro sensors, with an adaptable thickness ranging from 0.007 to 0.02mm, significantly enhance the sensitivity of the sensor, and the extensibility ensures that the diaphragm does not rupture after repeated deformation, and the corrosion resistance is suitable for the complex working environments of industrial / vehicle-mounted sensors.
Miniature medical device components such as the precision cannula of a miniature endoscope and the miniature clamping/slicing components for minimally invasive surgeries, with an appropriate thickness ranging from 0.01 to 0.03 mm, enable ultra-thin realization of the devices, reducing surgical trauma, high purity to avoid impurity contamination of medical devices, and the strength of titanium can meet the precise operation requirements of the devices; the base materials for biosensors such as the base for miniature biosensors for blood glucose/blood oxygen, with an appropriate thickness ranging from 0.008 to 0.02 mm, ultra-thin to enhance the skin-fitting/implantability of the sensors, resistant to corrosion by biological fluids, and high purity to avoid interfering with the detection accuracy of the sensors.
The ultra-thin titanium foil possesses excellent characteristics such as high rigidity, low surface density, fatigue resistance, and excellent acoustic conductivity. It has become the core membrane material for high-end HiFi acoustic devices, replacing traditional aluminum foil and polyester film. It is a high-end upgrade option in the field of acoustics. Its core applications include high-frequency speaker membranes and high-end earphones diaphragms, with suitable thickness ranging from 0.01 to 0.05 mm (mainstream 0.02 to 0.03 mm).
