In simple terms, Ti-6Al-4V has nearly double the Gr5 titanium alloy tensile strength (830-950 MPa) of Gr2 pure titanium (450-550 MPa), making it far more pressure-resistant.
But the actual pressure capacity also depends on the wall thickness. For example, our Gr5 tubes with 9.5mm walls can reliably handle 140 MPa in real-world tests. If you upgrade to beta titanium alloys, they can even push past 200 MPa!
Choosing the Right Titanium Tube Isn’t Just About Strength
Different titanium alloys excel in different scenarios:
-
General high-pressure use? Gr5 (Ti-6Al-4V) offers the best balance of cost and performance (ideal for 100-160 MPa).
-
Extreme pressure needs? Beta alloys like Ti-15V-3Cr-3Sn deliver unmatched strength.
-
Corrosion resistance? Ti-0.2Pd handles acids and salt spray like a champ.
-
Temperature extremes? Ti-6242 stays strong at 450°C, while Gr7 remains tough at -196°C.
Picking a titanium tube is like choosing a car—you don’t always need the most expensive one, just the right one for the job! Want a cost-effective workhorse? Gr5 is your go-to. Need to push limits? Beta titanium’s got your back.
Bottom line:
Gr5 tubes outperform Gr2 by 2X—9.5mm walls hold steady at 140 MPa, while beta alloys smash past 200 MPa!
