Iron is probably one of the most abundant metals on the earth, being used on the largest scale of any metal. When pure, iron is a lustrous shiny silver-white metal which is soft and very malleable. Iron is also well known for its properties like high tensile strength, good electrical and magnetic shielding properties. It finds applications in various areas due to its unique characteristics.
High Purity Iron foil produced by Industrial Metal Powders (India) Pvt. Ltd. is manufactured from the electrodeposited plates. IMP specializes in producing High Purity Iron Foil in various thicknesses and sizes for industrial and research applications. IMP offers iron up to 99.99% purity which is an essential requirement in various industries. High Purity Iron Foil finds its applications in various forms and industries such as food, Pharmaceutical & Cosmetics, Medical Devices, Research & Laboratory, Automotive, Aerospace, etc.
Specifications of High Purity Iron Foil:
IMP produces iron foils in varying gauge thicknesses including less than 0.08 mm as per customer requirements. There are certain specification standards which need to be followed while producing iron foils. The main mechanical, electrical and magnetic properties of the foil are dependent on the process variables and on its thickness.
| Thickness | Width | Length |
| 0.001″ to 0.003″ | 0.5″ to 2″ | 1″ – 12″ maximum |
| 0.004″ to 0.010″ | 0.5″ to 4″ | 1″ – 12″ maximum |
| 0.011″ to 0.030″ | 0.5″ to 6″ | 1″ – 24″ maximum |
Chemical Composition:
The chemical composition of iron foil consists of Carbon, Nitrogen, Sulfur, and Oxygen in different quantities as mentioned in the below table.
| Element | Value (ppm) |
| C | 10 – 14 |
| N | 5 – 6 |
| S | 3 – 4 |
| O | 30-60 |
How Iron Foil is Made?
Iron foil is made from electro deposited plates which are worked in the form of foil stock that is produced from high-quality rolling ingots and concast coils. After the foil stock is made, it must be reduced in thickness to make the iron foil. This is accomplished in a rolling mill, where the material is passed several times through metal rolls called work rolls. As the sheets of iron pass through the rolls, they are squeezed thinner and extruded through the gap between the rolls.
The metal rolls are paired with heavier rolls called backup rolls, which apply pressure to help maintain the stability of the metal rolls. This helps to hold the product dimensions within tolerances. Both the metal and backup rolls rotate in opposite directions. Lubricants are added to facilitate the rolling process. During this rolling process, the iron occasionally must be annealed (heat-treated) to maintain its workability. Iron foils can be very thin because the more malleable a metal, the thinner foil can be made with it. In some cases, metals can also be rolled down as thin as 0.001″ to be used as an evaporation source in microelectronics, optics, magnetics, MEMS, and hard resistant coatings.
Conclusion:
High purity Iron Foil is now being used on a large scale in various industrial and research applications. Iron foils may be used as a substrate for growing graphene by chemical vapor deposition (CVD). IMP is a world-class manufacturer of high purity iron foil and capable of meeting any technical requirement of your industrial need.
