1.Product Overview
Argon (Ar) is a colorless, odorless, and non-flammable inert gas. It is approximately 1.4 times heavier than air and has a low thermal conductivity. Due to its chemically inert nature, it does not react with most materials, making it an ideal shielding and protective gas for numerous industrial processes.
Molecular Formula: Ar
CAS Number: 7440-37-1
UN Number: UN1006 (compressed argon), UN1951 (liquid argon)
Hazard Class: 2.2 – Non-flammable, non-toxic gas
High Purity Grades
We offer argon in multiple purity grades to meet the specific needs of your application, and the liquid argon price varies based on the purity:
|
Grade |
Purity (≥) |
Typical Impurities (≤ ppm) |
|
Industrial Grade |
99.99% |
O₂: 10 ppm, N₂: 50 ppm, H₂O: 15 ppm |
|
High Purity Grade |
99.999% |
O₂: 2 ppm, N₂: 5 ppm, H₂O: 3 ppm |
|
Ultra-High Purity Grade |
99.9999% |
O₂: 0.2 ppm, N₂: 0.5 ppm, H₂O: 0.2 ppm |
2.Key Properties
Boiling Point: -185.8°C (-302.4°F)
Melting Point: -189°C (-308.2°F)
Relative Density (air = 1): 1.38 (heavier than air)
Solubility in Water: Slightly soluble
3.Applications
Argon's inert properties make it an indispensable gas across a wide range of industries:
Welding & Metal Fabrication: As a shielding gas in TIG and MIG welding, argon protects the molten weld pool from oxidation and contamination. It is essential for welding aluminum, stainless steel, titanium, and other non-ferrous metals.
Metallurgy: Used in the Argon Oxygen Decarburization (AOD) process for stainless steel production, as well as a protective blanket during casting and heat treatment operations to prevent oxidation.
Electronics & Semiconductor Manufacturing: Acts as a carrier or purge gas in the production of silicon wafers and other sensitive electronic components, where purity is critical for product yield.
3D Printing (Additive Manufacturing): Provides an inert atmosphere in powder bed fusion processes, preventing oxidation of metal powders such as titanium and aluminum alloys.
Fire Suppression Systems: Used as a component in inert gas fire suppression systems, including IG-541 (a mixture of nitrogen, argon, and carbon dioxide), which is designed for high-value environments requiring clean, residue-free extinguishing agents.
Laboratory & Analytical Instruments: Serves as a carrier gas for ICP spectroscopy and other analytical equipment.
Lighting: Fills incandescent and fluorescent bulbs to protect the filament and improve efficiency.
4.Safe Storage & Transport
LUZHEN prioritizes the safety of our products from our facility to yours. Argon is classified as a Class 2.2 non-flammable, non-toxic gas and is regulated as a dangerous good for transport. We ensure full compliance with all applicable transport regulations, including proper packaging, labeling, and documentation.
Storage Recommendations: Store cylinders upright in a well-ventilated, cool, and dry area away from heat sources and direct sunlight. The storage area temperature should not exceed 40°C (104°F). Cylinders must be securely fastened to prevent tipping.
Transport Compliance: Our shipments strictly follow dangerous goods transport regulations, with properly labeled vehicles and qualified personnel. Whether via cylinder, dewar, or cryogenic tanker, we ensure safe delivery to your site.
Safety Data Sheets (SDS): We provide comprehensive Safety Data Sheets (SDS) with every shipment, detailing product properties, safe handling procedures, storage requirements, and emergency response measures. Our team is always available to assist with any safety or compliance questions.
