What is Ultra-Pure Iron?
Ultra-Pure Iron, also known as High Purity Iron, is a specialized grade of iron with a purity level of 99.99% (4N) or higher. It is produced through advanced electrolytic or chemical purification processes to minimize the content of interstitial elements like carbon, oxygen, nitrogen, and sulfur. This exceptional purity gives it superior magnetic, electrical, and mechanical properties, making it an indispensable material for high-tech and mission-critical applications.
Huaxiao Metal is a trusted global supplier of ultra-pure iron, delivering exceptional quality and consistency for the world’s most demanding industries.

FAQ
What is the difference between 4N (99.99%) and 5N (99.999%) ultra-pure iron?
The primary difference is the level of impurities. 5N pure iron has ten times fewer impurities than 4N, making it suitable for the most critical applications where material integrity and performance are paramount, such as in semiconductor and advanced research fields.
4N vs. 5N Ultra-Pure Iron: Which Grade Do You Really Need?
What is your Minimum Order Quantity (MOQ)?
Our MOQ is flexible and depends on the product form and stock availability. Please contact our sales team with your requirements, and we will do our best to accommodate your needs.
How do you package the material to prevent contamination?
All ultra-pure iron products are cleaned and packed in a vacuum-sealed plastic bag within a controlled environment. This is then placed in protective containers (such as drums or wooden cases) to ensure the material arrives in pristine condition.
What information do I need to provide to get a quote?
