Aerospace Gr2 Titanium Foil is made from Grade 2 commercially pure titanium (Ti ≥ 99.2%) and produced using aerospace-grade processes with strict quality control. It is an ultra-thin titanium foil/strip designed for lightweight structures and corrosion-resistant parts in aerospace applications. This material offers a well-balanced combination of strength, ductility, and corrosion resistance. Compared with Gr1, it provides higher strength while still maintaining excellent formability, making it a reliable and cost-effective choice for non–high-strength alloy applications in aerospace engineering. It is commonly used in aircraft fuselage skins, interior structural parts, tubing components, and non–high-temperature engine parts. These applications require stable quality, consistent performance, and full traceability, which this material is designed to ensure.

Aerospace Gr4 Titanium Foil is a high-strength titanium foil made from Grade 4 commercially pure titanium, produced to aerospace standards such as AMS 4901. It offers the highest strength among commercially pure titanium grades, while still maintaining good corrosion resistance and a stable α-phase structure without heat treatment. This ensures reliable performance in long-term use under stress, vibration, and harsh aerospace environments. Vacuum melting and precision rolling with strict control of O, N, and H elements provide consistent quality and stable properties. Compared with Gr1 and Gr2 titanium foils, Gr4 provides higher strength and better structural stability. Gr1 is the most ductile, Gr2 offers a balance of strength and formability, while Gr4 is chosen when higher strength and load-bearing performance are required. It is commonly used in aircraft structural parts, thin-wall components, piping systems, and other aerospace parts that require high strength, corrosion resistance, and long-term reliability.
