AMS 4902 Grade 2 Titanium Foil: Specification, Documentation and RFQ Guide

AMS 4902 Grade 2 titanium foil is a product-specific aerospace material reference for Grade 2 titanium foil inquiries. A complete request keeps the AMS designation, Grade 2 identity, product form, dimensions, delivery condition, surface requirements, and inspection documents together. This prevents a generic “titanium foil” request from being matched to the wrong grade or form.

1. Product identity

State the material as AMS 4902 Grade 2 titanium foil. Grade 2 commercially pure titanium is commonly selected for a balance of corrosion resistance, formability, and general industrial or aerospace material requirements. The current specification revision and the exact order requirements must be confirmed before production.

2. Specification and RFQ fields

3. Application boundary

Grade 2 foil can be considered where the design needs commercially pure titanium with corrosion resistance and useful forming characteristics. Application suitability still depends on thickness, temperature, loading, joining or forming method, surface condition, and the customer’s acceptance criteria. A standard reference should not be presented as a guarantee for every application.

4. Related Titanium Valley material pages

See the AMS 4902 Grade 2 titanium foil product page and the related Grade 2 titanium foil page. For comparison, the AMS 4901 Grade 4 titanium foil page represents a different grade and specification reference.

5. FAQ

What is the difference between AMS 4902 Grade 2 and AMS 4901 Grade 4 foil?
They identify different commercially pure titanium grades and specification references. The correct choice depends on the drawing, required properties, formability, dimensions, and qualification requirements.

What documents should be requested?
Request the current revision reference, certificate, heat/lot traceability, dimensional inspection, surface inspection, and any additional records stated in the purchase order.

Is a general Grade 2 foil description enough for an RFQ?
No. Include the exact standard, dimensions, condition, quantity, tolerances, surface requirements, and documentation.

6. RFQ checklist

Include AMS 4902, Grade 2, foil dimensions, tolerances, surface and delivery condition, quantity, certificate requirements, destination, and requested delivery date. Submit the request through the Titanium Valley RFQ page.
