Material properties of Titanium Grade 2 alloy tubes

The core advantages of Titanium Grade 2 (also known as TA2) alloy tubes come from their stable chemical composition and excellent comprehensive performance. Its chemical composition is titanium as the balance, and the content of major impurity elements is extremely low, such as aluminum ≤0.3%, vanadium ≤0.08%, iron ≤0.3%, silicon ≤0.03%, etc., which ensures the purity and corrosion resistance of the material. In terms of physical properties, the density of the alloy is about 4.5g/cm³, which is only 60% of that of stainless steel. It has both high strength (tensile strength 340-490MPa) and high plasticity (elongation ≥30%), and is suitable for manufacturing lightweight tubular parts that need to bear loads.

Implementation standards for Titanium Grade 2 alloy tubes

In terms of implementation standards, Titanium Grade 2 alloy tubes must comply with a number of international and domestic specifications, including:

ASTM B265 (American Society for Testing and Materials standard for titanium and titanium alloy plates, strips and foils)

ASTM F136 (medical implant grade titanium alloy standard, emphasizing biocompatibility)

GB/T 3621-1994 and GB/T 13810-1997 (Chinese national standards, covering titanium and titanium alloy processed products)

Product form of Titanium Grade 2 alloy tube

Titanium Grade 2 alloy tube is mainly divided into two categories: seamless tube and welded tube. Common forms include:

Seamless tube: suitable for high-pressure and high-precision scenarios, such as aviation hydraulic systems

Welded tube: low cost, suitable for general industrial pipelines

Core application areas of Titanium Grade 2 alloy tube

1. Medical device field

With excellent biocompatibility (non-magnetic, non-toxic, non-sensitizing), Titanium Grade 2 alloy tube is used to manufacture bone connectors, artificial joint catheters, dental implant accessories, etc., which can be implanted in the human body for a long time without causing immune rejection.

2. Aerospace and marine engineering

In the aviation field, it is used to manufacture engine fuel pipes and hydraulic pipelines; in marine engineering, due to its seawater corrosion resistance, it is widely used in submarine detection equipment catheters and ship propulsion system pipelines.

3. Chemical and industrial fields

Applicable to heat exchanger tube bundles and reactor connection pipes in strong acid and strong alkali environments, such as chlor-alkali chemicals and corrosive fluid transportation in pharmaceutical production lines
