Grade 9 Titanium Plate
Grade 9 Titanium Plate (Ti-3Al-2.5V Plate) is a medium-strength alpha-beta titanium alloy combining excellent corrosion resistance, good weldability, and higher mechanical strength than commercially pure titanium.
Product Introduction
Product Overview
Grade 9 Titanium Plate (Ti-3Al-2.5V Plate) is a medium-strength alpha-beta titanium alloy combining excellent corrosion resistance, good weldability, and higher mechanical strength than commercially pure titanium.
Positioned between Grade 2 and Grade 5 titanium alloys, Grade 9 provides an effective balance of strength, formability, corrosion resistance, and fabrication efficiency. It is widely used in aerospace, marine, chemical processing, and industrial equipment applications where both structural performance and manufacturing flexibility are required.

Key Product Advantages
With a typical tensile strength of ~620 MPa and a density of 4.48 g/cm³, Grade 9 provides reliable structural strength while saving dead weight.
The 3% Al and 2.5% V alloy composition facilitates a stable passive oxide layer, ensuring long-term durability in seawater and mild chemical media.
Controlled multi-roll flattening minimizes residual stress, yielding a precise surface (Roughness: 1.6-3.2μm) optimized for automated laser cutting and CNC machining.
Every plate undergoes 100% ultrasonic inspection according to AMS 2631 or AMS STD-2154 requirements to help ensure internal quality and material consistency.
