What is annealed zirconium 60702 sheet?
Annealed zirconium 60702 sheet is a high-purity zirconium alloy material that has undergone a special heat treatment process. An annealed zirconium 60702 plate has excellent corrosion resistance, good machinability, and outstanding high-temperature stability. This material is widely used in high-end fields such as the chemical industry, nuclear power, medical treatment, and aerospace, and is an ideal choice for metal structural parts in harsh environments.
Core advantages of annealed zirconium 60702 plate
1. Excellent corrosion resistance
Excellent performance in strong acid environments such as hydrochloric acid, sulfuric acid, and nitric acid
Resistant to seawater corrosion, suitable for marine engineering
Resistant to chloride ion stress corrosion cracking (SCC), better than stainless steel and titanium alloy
2. Optimized mechanical properties (annealed state)
Performance index value
Tensile strength ≥450 MPa
Yield strength ≥275 MPa
Elongation ≥20%
Hardness (HV) 120-180
Annealing eliminates cold working stress, improves plasticity and toughness, and makes it easier to stamp, weld, and machine.
3. High temperature stability
Melting point: 1852°C
Operating temperature range: -200°C to 400°C (long-term stability)
Low thermal expansion coefficient (5.7×10⁻⁶/°C), reducing thermal deformation
4. Biocompatibility (medical grade applications)
Meets ISO 5832-3 and ASTM F2384 medical standards
Non-toxic, non-magnetic, suitable for implants and surgical instruments
Main applications of annealed zirconium 60702 sheet
🔹 Chemical equipment manufacturing
Reactors, heat exchangers, tower linings
Acid-resistant pumps, valves, and piping systems
🔹 Nuclear power industry
Nuclear fuel cladding tubes
Reactor internal structural parts
🔹 Medical implants
Orthopedic implants (such as artificial joints, bone screws)
Dental implants and surgical tools
🔹 Aerospace and marine engineering
Engine high-temperature resistant components
Deep-sea exploration equipment pressure shell
Annealed vs. Comparison of cold-rolled zirconium 60702 plates
Characteristics Annealed Cold-rolled
Strength Moderate (easier to process) Higher (but brittleness increases)
Plasticity Excellent (elongation ≥ 20%) Lower (easy to crack)
Residual stress Low (reduce deformation risk) High (subsequent annealing required)
Applicable processes: Welding, deep stamping, High-strength structural parts
✔ Selection suggestions:
If welding, stamping, or complex forming is required, the annealed state is preferred
If higher strength is required and no secondary processing is required, the cold-rolled state can be selected
How to choose high-quality annealed zirconium 60702 plates?
✅ Key quality indicators

Are there any supply cases for the nuclear power/medical industry?
FAQ
How to avoid hydrogen embrittlement of annealed zirconium plates?
Avoid contact with an acidic environment during storage
Use argon protection during welding to prevent hydrogen absorption
Can secondary cold processing be performed on annealed plates?
Yes, but the deformation needs to be controlled to avoid cracking caused by excessive hardening.
How is the corrosion resistance of zirconium 60702 compared to TA2 titanium plate?
In high-temperature concentrated hydrochloric acid and sulfuric acid, zirconium has better corrosion resistance than titanium, but titanium is better in oxidizing media (such as nitric acid).
