Medium-Strength Alpha-Beta Titanium Alloy for Lightweight Tubing & Structural Parts
Overview
Grade 9 Titanium, also known as Ti-3Al-2.5V, is a medium-strength alpha-beta titanium alloy offered by BOZE Metal, designed to bridge the gap between commercial pure titanium and high-strength Grade 5 (Ti-6Al-4V) alloy. With lower alloy content than Grade 5, this grade delivers excellent strength-to-weight ratio, superior formability, and outstanding weldability, making it the preferred choice for high-precision tubing, lightweight structural components, and general industrial applications that require more strength than pure titanium but greater formability than Grade 5.
Widely used in aerospace tubing, automotive lightweight parts, and hydraulic systems, Grade 9 (Ti-3Al-2.5V) combines lightweight properties with reliable mechanical performance. BOZE Metal supplies this grade in various raw material forms, with custom fabricated parts available through BOZO CNC-Ti precision machining services for tailored industrial solutions.
