AMS4901 (CP Grade 4 Titanium) Titanium Sheet, Strip, And Plate, Commercially Pure, Annealed
Golden Sunbird Metals supplies high-quality AMS4902 CP Grade 2 titanium plate and sheet for applications that require excellent corrosion resistance, reliable formability, and dependable performance. Commercially pure Grade 2 titanium is one of the most widely used titanium materials because it offers a strong balance of moderate strength, low density, and outstanding resistance to seawater, chloride exposure, and many corrosive chemical environments. Manufactured to meet AMS 4902 requirements, our titanium plate and sheet are available in a variety of thicknesses, sizes, and custom specifications to support precise fabrication and project needs. CP Grade 2 titanium is widely used in chemical processing, marine engineering, desalination equipment, heat exchangers, and other industrial applications where long service life and material stability are essential. At Golden Sunbird Metals, we are committed to providing premium titanium products with consistent quality, strict inspection, and professional service for customers worldwide.

Technical Specifications
| Specification | Value |
| Standard | AMS4901 Titanium Sheet, Strip, And Plate, Commercially Pure, Annealed, 70.0 Ksi (485 MPa) |
| Grade | Grade 4 |
| Melting Practice | Alloy shall be produced by electron beam cold hearth or plasma arc cold hearth melting method or multiple melting with the final melting cycle under vacuum. When multiple melting is used, the first melt shall be made using a vacuum consumable electrode, non-consumable electrode, electron beam cold hearth, or plasma arc cold hearth melting practice. The subsequent melt or melts shall be made using vacuum arc remelting (VAR) practice. Alloy additions are not permitted in the final remelt cycle. |
| Type | Titanium Sheet, Strip, and Plate |
| Dimension | Strip: Width 25.4-1219.2mm x Thickness 0.41-4.75mm |
| Sheet: Width 1000-2000mm x Thickness 0.41-4.75mm | |
| Plate: Width 1000-2000mm x Thickness 4.75-101.6mm | |
| Density | 4.51g/cm³ |
| Condition | Sheet and Strip: Hot rolled with or without subsequent cold reduction, annealed, descaled, and leveled, having a surface appearance comparable to a commercial corrosion-resistant steel No. 2D finish. Plate: Hot rolled, annealed, descaled, and flattened, having a surface appearance comparable to a commercial corrosion-resistant steel No. 1 finish. Plate products shall be produced using standard industry practices designed strictly for producing plate stock to the procured thickness. Bar, billet, forgings, or forging stock shall not be supplied in lieu of plate. |
