When sourcing or selling titanium foil on Alibaba.com, understanding the configuration options is critical for matching buyer requirements. Titanium foil is not a one-size-fits-all product—different grades, thicknesses, and certifications serve distinct application scenarios in industrial, outdoor, and marine environments.
Titanium Grades Explained: The ASTM B265 standard defines multiple titanium grades, each with unique properties [3]. Grade 1-4 are commercially pure titanium, with Grade 2 being the most widely used for marine applications due to its excellent corrosion resistance and formability. Grade 5 (Ti-6Al-4V) offers the highest strength but at higher cost. Grade 7 provides superior corrosion resistance for extreme chemical environments. For Southeast Asian exporters targeting industrial and marine buyers, Grade 2 represents the sweet spot between performance and affordability.
Thickness & Dimension Options: Titanium foil typically ranges from 0.01mm to 2mm in thickness, with widths from 610mm to 1220mm and lengths up to 6100mm [6]. Thinner foils (0.01-0.1mm) suit electronics and precision applications, while thicker sheets (0.5-2mm) serve structural and marine uses. Sellers on Alibaba.com should clearly specify thickness tolerances as buyers in industrial procurement prioritize dimensional accuracy.
Certification Requirements: Compliance with ASTM B265, AMS 4902, ASME SB265, and DIN 17860 standards is often mandatory for B2B buyers, especially in aerospace, marine engineering, and medical device sectors [6]. Southeast Asian exporters should obtain mill test certificates (MTC) and third-party inspection reports to build trust with international buyers on Alibaba.com.
