Titanium Sheet AMS 4901

Product Introduction

AMS 4901 is the aerospace material specification that governs the sheet used for aircraft skin and structural panels, and the audit trail matters as much as the material itself. This page is for buyers who have to show that the sheet satisfies the specification, including dimensional tolerance and internal soundness, rather than simply supplying a titanium sheet that looks correct.

Specification Table

Applications and Titanium Advantages

The sheet is used for fuselage skin, aerospace structural plate work and high-temperature pressure-tight skins where both the surface and the interior of the material are inspected. Because the specification is audited, buyers should confirm the thickness tolerance, the ultrasonic inspection level, the surface acceptance criteria and the certificate package before releasing a purchase order.

• The sheet is produced against the AMS 4901 specification, so chemistry, mechanical properties and tolerances are documented against a recognised aerospace standard.
• Surface finish and internal non-destructive testing records are provided, which is normally the point where lower-grade sheet fails an audit.
• Flat and consistent sheet helps forming, stretch-shaping and machining operations hold their tolerances.

Quality and Purchasing Information

Aerospace sheet is released against documents, so the enquiry should state thickness, width, length, quantity, the inspection level required and whether a third-party witness or specific certificate format is needed. Tibars reviews the AMS 4901 requirement against the sheet offered and flags any point where the inspection package has to be agreed before the order is placed.

• State the grade, size, tolerance, quantity and delivery condition of this AMS 4901 titanium sheet at enquiry stage so pricing can be issued without re-quoting.
• Ask for the mill test certificate and any inspection records that the project requires for this AMS 4901 titanium sheet, and confirm them against the purchase specification.
• Engineered or non-standard this AMS 4901 titanium sheet can be reviewed from a drawing together with the working medium and operating conditions.
