R60705 zirconium cubic parts for scientific research

Zirconium alloy blocks are high-performance metallic materials formed by adding alloying elements such as tin, niobium, iron, and chromium to metallic zirconium as the matrix. Their core advantages are extremely low thermal neutron absorption cross section, excellent corrosion resistance, good mechanical properties and biocompatibility. They are key strategic materials in nuclear industry, chemical industry, medical and other fields.

I. Product Introduction

1. Core Components (Typical Grades)
Zirconium alloy blocks are based on high-purity zirconium (Zr≥95%), with trace alloying elements added to optimize performance. Nuclear-grade zirconium requires strict control of hafnium (Hf) content (≤0.01%).

Zr-702 (Industrial Pure Zirconium): Zr≥99.2%, Hf≤4.5%, Fe+Cr≤0.20%, excellent corrosion resistance, moderate strength.

Zr-705 (Zr-2.5Nb): Contains 2.0%~3.0% niobium, significantly improved strength, heat resistance, and corrosion resistance, most widely used.

Zircaloy-4 (Zr-4): Contains 1.2%~1.5% Sn, 0.2%~0.4% Fe, 0.05%~0.15% Cr, mainstream nuclear-grade, low hydrogen absorption.

N36 (Domestic Nuclear Grade): Zr-Nb series, containing 1.0%~1.2% Nb and 0.2%~0.3% Fe, resistant to high-temperature corrosion, used in Hualong One.

2. Key Performance Characteristics

Nuclear Performance: Thermal neutron absorption cross-section of only 0.18 pegnats (far lower than iron's 2.6 pegnats), does not interfere with nuclear reactions, and has excellent neutron economy.

Corrosion Resistance: Stable in high-temperature and high-pressure water/steam at 300~400℃, resistant to most strong acids (except hydrofluoric acid), seawater, and alkaline solutions.

Mechanical Properties: Tensile strength 400~900MPa, yield strength 250~700MPa, good plasticity, easy to process and shape.

Other Characteristics: Melting point 1852℃, high-temperature resistant; non-magnetic, excellent biocompatibility, and resistant to neutron radiation.

3. Specifications and Conditions

Dimensions: Square blocks (10~500mm), round ingots (φ50~φ500mm), forgings, billets; non-standard sizes can be customized.

Conditions: Forged, annealed, quenched; nuclear grade requires vacuum melting, non-destructive testing, and precise composition control.

Standards: ASTM B550, GB/T 26311, AMS 6925.

II. Main Application Areas

1. Nuclear Industry (Core Application, accounting for 80%+)

Fuel Cladding Tubes: Cladding for pressurized water reactor/boiling water reactor fuel rods, encasing uranium pellets, preventing leakage, and resisting corrosion from 350℃ high-pressure water.

Core Structural Components: Pressure tubes, guide tubes, positioning grids, end plugs, container tubes, supporting nuclear fuel assemblies.

Nuclear Reactor Components: Key materials for nuclear submarine and nuclear-powered aircraft carrier reactors, ensuring safe and efficient nuclear reactions.

2. Chemical and Corrosion-Resistant Industries

Highly Corrosion-Proof Equipment: Heat exchangers, reactors, pumps, valves, pipelines, and tower linings for hydrochloric acid, acetic acid, and urea production.

Seawater Engineering: Seawater desalination, offshore platforms, ship pipelines, and condensers; resistant to long-term seawater corrosion.

Chemical Containers: Corrosion-resistant storage tanks, electrolytic cells, and filters for chlor-alkali, pharmaceutical, and fine chemical industries.

3. Medical and Biological Fields

Orthopedic Implants: Zr-2.5Nb alloy artificial hip and knee joints, bone plates; elastic modulus close to human bone, wear-resistant, and non-rejectable.

Dental Restoration: Dental implants; excellent biocompatibility, aesthetics, corrosion resistance, and high strength.

Surgical Instruments: Minimally invasive instruments and orthopedic tools; non-magnetic, sterilization-resistant, stain-resistant, and rust-proof.

4. Aerospace and Military Industries

Aero-engines: Combustion chamber, nozzle, and blade coatings; high temperature resistance (1000℃+), lightweight, and creep-resistant.

Aerospace Components: Rocket engine nozzles, satellite separation mechanisms, hydrogen storage systems; radiation resistant and hydrogen-absorbing stable.

Military Equipment: Hypersonic weapon warheads, scramjet engine components; extreme temperature resistance and corrosion resistance.

5. Other High-End Fields
Metallurgical Industry: Special steel deoxidizers, alloy additives; improving the strength, toughness, and corrosion resistance of steel.

Electronics & Semiconductors: Sputtering targets, vacuum devices, integrated circuit heat sinks; high purity, low impurities, and stable thermal conductivity.

Precision Manufacturing: Instrument parts, optical bearings, cold-welding resistant components; high precision, wear resistance, and dimensional stability.
