99.99% Hafnium Rod
Hafnium, a refractory metal with chemical properties very similar to zirconium but unique nuclear properties, has long existed as a byproduct of producing nuclear grade zirconium in industrial history. However, with the development of technology, it has been discovered that hafnium plays an irreplaceable "key role" in specific fields due to its extremely high thermal neutron absorption cross section, excellent high-temperature strength, and corrosion resistance.
The high-purity hafnium rod we provide (purity ≥ 99.99%) is refined through advanced processes such as electron beam melting, which minimizes the content of interstitial impurities such as oxygen and nitrogen, enabling it to maintain its inherent advantages while having better processing performance and reliability, making it an indispensable core material in the fields of nuclear energy, aerospace, and plasma.
Description
Production process and quality inspection
Advanced production technology:
- Raw material purification: High purity sponge hafnium is used as the raw material.
- Melting technology: The core process is electron beam bed melting (EBM) or vacuum consumable arc melting (VAR). These two technologies are carried out in an ultra-high vacuum environment, which can effectively evaporate and remove low melting point impurities, obtaining ingots with uniform composition and dense structure.
- Heat processing and heat treatment: The ingot is forged and rolled multiple times under a protective atmosphere, gradually forming into a rod. Through precise heat treatment, internal stress is eliminated, grain structure is optimized, and the foundation is laid for subsequent processing.
Comprehensive quality inspection:
- Purity analysis: Each batch of products is sampled for GDMS (glow discharge mass spectrometry) analysis, and a testing report is provided to ensure that the purity meets the standard.
- Non destructive testing: Ultrasonic testing is performed on bar materials to detect internal cracks, inclusions, and other defects, ensuring structural integrity.
- Mechanical performance testing: Random sampling is used to conduct tensile tests at room temperature and high temperature, providing mechanical performance data such as strength and plasticity.
Dimensional and surface inspection: Use precision measuring tools to ensure diameter and straightness tolerances; Check the surface smoothness, without deep scratches or folds.
FAQ
Q: Q1: What is the main difference between hafnium rod and zirconium rod? How should I choose?
A: A: The most crucial difference lies in nuclear performance. Hafnium is an extremely strong neutron absorber used for control rods; Zirconium is transparent to neutrons and is used for fuel rod cladding. Please choose based on your core application requirements (neutron absorption or conduction).
Q2: What is the minimum order quantity (MOQ) and delivery time for your hafnium rods?
A: MOQ depends on the specifications, with a standard specification typically of 1 kilogram. The delivery time for regular products is 4-6 weeks after the contract takes effect, and customized specifications need to be negotiated specifically.
Q3: Can you provide hafnium rods that meet specific ASTM or AMS standards?
A: Okay. We can produce materials that meet ASTM B776 and other specifications according to your requirements, and clearly label them in the warranty certificate.
