Products Description
The Zr2.5Nb alloy bar specifically consists of zirconium (Zr) and niobium (Nb) in a ratio of 2.5% - a titanium subsequent alloy. This alloy is distinguished by superb traits of strength, and durability, as well as persistent SCC (stress corrosion cracking), which makes the alloy suitable for marine and aerospace engineering, as well, other sophisticated industries that face severe environmental and mechanical challenges.
Features of Zr2.5Nb Alloy:
Mechanical Properties
Strength: The addition of niobium improves the strength of the alloy in comparison to pure zirconium. While pure zirconium boasts relatively high strength, it is exceptionally lacking in tensile stress.
Corrosion Resistance: The Zr2.5Nb alloy has excellent corrosion resistance, particularly in regions of the world with excess chloride, like the ocean.
Resistance to Stress Corrosion Cracking: The alloy possesses significantly higher resistance to stress corrosion cracking than pure zirconium. This is one of the most important attributes for materials which undergo fluid corrosion in conjunction with mechanical stress.
Fatigue Endurance: Zr2.5Nb has good endurance to repeated loads, which is valuable for components designed to take on multiple loads.
High Temperature Operation: The alloy can stand very high temperatures up to 1850 degrees Celsius, maintaining relative strength and stability.
Applications of Zr2.5Nb Alloy Bar:
Zr2.5Nb alloy bars are widely used across multiple industries due to their excellent comprehensive properties. In the nuclear energy sector, this alloy is the material of choice for manufacturing critical components such as reactor pressure tubes and fuel cladding, where its outstanding radiation resistance and corrosion resistance ensure the long-term safe operation of nuclear facilities.
Aerospace: The Zr2.5Nb alloy bars are specifically utilized for high pressure vessels, structural components of overriding importance in the aerospace industry, and also in the landing gears of the aircraft. The material is very advantageous for aerospace vehicles due to its high strength to weight ratio.
Marine: Zr2.5Nb alloy bars are applicable in offshore structures, marine piping systems, and ship hulls because of their remarkable resistance to corrosion, making them highly suitable for marine-based applications.
Chemical Processing: For the aggressive conditions that accompany chemical processing, the Zr2.5Nb alloy bars work well due to their remarkable corrosion resistance.
Desalination Plants: This alloy is incorporated in desalination plants due to its resistance to highly corrosive seawater.
Power Generation: Zr2.5Nb alloy bars can also be used in heat exchangers due to their ability to withstand high temperatures and harsh chemicals.
FAQ
What is the MOQ?
A: Depends on quantity, generally, no MOQ limit.
How to pay for it?
A: A bank transfer (T/T) will be acceptable.
What is the delivery time?
A: around 7-20 days which depends on the quantity and production.
What is the package?
A: cartoon case or plywood case.
What is the lead time?
A: from order placed to cargo receiving will take around 10-25 days.
What is the delivery method?
A: Generally, we send cargo by UPS, DHL or FedEx. Also, we can send by sea to seaport or by air to the closest airport.
What makes Zr2.5Nb alloy special?
A: It's like the "superhero" of metals - fights rust better than stainless steel (even in seawater), handles radiation like a champ in nuclear plants, and stays strong at high temperatures while being lighter than steel.
Where is it commonly used?
A: You'll find it in:
• Nuclear reactor "armor" (pressure tubes)
• Artificial joints that last decades
• Chemical tanks that resist strong acids
• Rocket parts that need to be light but strong
How does it compare to titanium?
A: Think of it as titanium's smarter cousin:
✓ Better at handling radiation
✓ More resistant to chemical attacks
✓ Just as body-friendly for implants
✗ But not quite as strong at extreme temps
Can it be recycled?
A: Yes! 100% recyclable without quality loss - old nuclear parts can become new medical implants.
Why is it expensive?
A: Three reasons:
Special zirconium is rare (harder to mine than iron)
Precise 2.5% niobium mix requires high-tech processing
Every batch gets NASA-level quality testing
Can small companies buy it?
A: Yes, but minimum orders usually start at 10kg (about 3 coffee mugs' worth) - most suppliers work with industrial buyers.
