TC4 titanium alloy flat bar

TC4, also known as Ti-6Al-4V (Grade 5), is the most widely used medium-to-high strength titanium alloy. As a modified α+β alloy, it offers the best balance of mechanical properties, processability, and weldability, making it the first titanium alloy extensively applied in the aerospace industry.

Key Characteristics

Excellent strength-to-weight ratio

Superior fatigue resistance

Good weldability and machinability

Stable performance up to ~500–540°C

Proven reliability in structural applications

Typical Applications

Aerospace structural components

Aero-engine compressor parts

Aircraft skins and load-bearing structures

High-performance industrial equipment

TA19 TITANIUM ALLOY BAR (Ti-6Al-2Sn-4Zr-2Mo)

High-Temperature Near-α Alloy for Extreme Environments

TA19 is a near-α titanium alloy designed for elevated temperature applications. Its composition includes:

α stabilizers: Aluminum (Al)

Neutral elements: Tin (Sn), Zirconium (Zr)
