When sourcing titanium for a new project, one of the first decisions buyers face is whether to choose pure titanium plate or titanium alloy plate. Both materials share titanium's core advantages - light weight, outstanding corrosion resistance, and biocompatibility - but they perform very differently once strength, formability, and cost enter the equation. Choosing the wrong one can mean overpaying for strength you don't need, or under-specifying a part that later fails in service.
This guide breaks down the real differences between pure titanium plate and titanium alloy plate, so you can match the right material to your application before you request a quote.
What Is Pure Titanium Plate?
Pure titanium plate - also called commercially pure (CP) titanium plate - is unalloyed titanium containing at least 99% titanium, with only trace amounts of oxygen, iron, carbon, nitrogen, and hydrogen controlling its properties. It's produced in four standard grades:
Grade 1 – the softest and most ductile grade, with the highest formability and corrosion resistance but the lowest strength.
Grade 2 – the most widely used CP grade, offering a practical balance of moderate strength, excellent weldability, and cold-forming performance. Often called the "workhorse" grade of the titanium family.
Grade 3 – higher strength than Grade 1 and 2, with good corrosion resistance, though it is less commonly stocked.
Grade 4 – the strongest of the CP grades, still weldable and formable, used where higher mechanical performance is needed without alloying.
Because it contains no strengthening alloy elements, pure titanium plate is generally easier to form, bend, and weld than alloy plate, and it typically costs less per kilogram - making it a common choice wherever corrosion resistance matters more than raw strength.
What Is Titanium Alloy Plate?
Titanium alloy plate is titanium combined with elements such as aluminum, vanadium, molybdenum, nickel, or palladium to significantly boost strength, temperature resistance, or corrosion performance in specific media. Common grades include:
Grade 5 (Ti-6Al-4V) – the most widely used titanium alloy worldwide, with roughly three times the strength of Grade 2, plus good weldability and heat resistance. It's the standard choice for aerospace, high-load structural parts, and marine components.
Grade 7 (Ti-0.2Pd) – CP titanium with a small palladium addition, giving it the best crevice-corrosion resistance of any commercial grade - ideal for aggressive chemical media.
Grade 9, Grade 12, Grade 23 – specialty alloys used where a specific combination of strength, weldability, or corrosion resistance in reducing environments is required.
The trade-off: alloy plate is harder to cold-form, generally costs more, and - in grades like Ti-6Al-4V - is not always the best choice when maximum weldability or the lowest possible cost is the priority.

Limited cold formability, often requires hot forming |
|
Weldability |
Excellent across all CP grades |
Good, but generally more demanding than CP grades |
|
Corrosion resistance |

Excellent, with alloy-specific advantages (e.g., Grade 7 for crevice corrosion) |
|
Typical cost |
Lower |
Higher, due to alloying elements and processing |
|
Common applications |
Chemical processing, desalination, heat exchangers, architecture, marine, medical |
Aerospace, high-strength structural parts, high-temperature service, marine hardware |
Which One Should You Choose?
Choose pure titanium plate (typically Grade 2) if your application prioritizes:
- Corrosion resistance in seawater, chlorides, or oxidizing chemicals
- Easy fabrication - bending, drawing, or deep forming
- Reliable weldability with standard procedures
- A more economical titanium solution for large or thick plate orders
Choose titanium alloy plate (typically Grade 5) if your application requires:
- High strength-to-weight ratio for structural or load-bearing parts
- Performance at elevated temperatures
- Aerospace, defense, or high-performance marine specifications
- Crevice-corrosion resistance in demanding process media (Grade 7)
In practice, many industrial buyers use both: pure titanium for pressure vessels, tanks, and heat exchanger components, and alloy plate for fasteners, structural brackets, or parts under mechanical load within the same system.
