Semiconductor materials: Indium metal foil can be used to manufacture semiconductor materials, such as transistors, integrated circuits, etc. It has good electrical and thermal conductivity, as well as high melting and boiling points, so it has important application value in semiconductor manufacturing.
Optical materials: Indium foil can be used to manufacture optical materials, such as reflectors, lenses, etc. It has good optical properties, such as high reflectivity, low absorption, etc., so it is also widely used in the optical field.
Radiation protection materials: Indium foil can be used to make radiation protection materials, such as X-ray shielding materials, nuclear radiation shielding materials, etc. It has good radiation protection performance, can effectively block X-rays and nuclear radiation, and protect human health.
Catalyst: Indium foil can be used to make catalysts, such as catalyst carriers, catalyst active ingredients, etc. It has good catalytic performance, can accelerate chemical reactions and improve reaction efficiency.
Other applications: Indium foil can also be used to make other electronic components such as batteries, solar cells, sensors, capacitors, and for the manufacture of metals, alloys, coatings, plastics and other materials.
Our products implement the most stringent quality management system. There are strict inspection standards for incoming materials, processes, final inspections, and factory inspections. Strict isolation measures will be adopted for unqualified processing to prevent unqualified products from flowing into the next process. Samples will be provided to customers according to customer requirements for re-inspection.
Vacuum packaging, the packaging quantity can be provided according to customer requirements and packaged separately.
Indium foil should be sealed and stored in a cool and dry environment to prevent it from reacting with moisture and oxygen in the air.
Q1: What is indium foil used for？
A: Indium foil is used in semiconductors for transistors and integrated circuits, in optics for reflectors and lenses, in radiation protection for X-ray and nuclear shielding, as a catalyst, and in other applications like batteries, solar cells, sensors, and various alloys and coatings.
Q2: Is indium a good heat conductor?
A: As a highly thermally conductive metal, indium exhibits a significantly higher thermal conductivity than traditional thermal interface materials (TIMs). Typically, TIMs have a thermal conductivity of approximately 3.8 W/m∙K, while indium boasts a thermal conductivity as high as 82 W/m∙K. This characteristic allows indium sheet to transfer heat more effectively, thereby reducing the operating temperature of semiconductor devices and improving system stability and reliability.
Q3: How thick is indium foil?
A: The thickness of indium foil varies depending on the application. Our company offers indium foil with thicknesses ranging from 0.05 mm to 2 mm, and custom thicknesses can be provided upon request, with a purity ≥99.99%. For specific specifications, please contact us for a quote.
Q4: Is indium foil malleable?
A: Indium metal foil possesses excellent ductility, allowing it to be stretched into extremely thin layers without breaking. It retains its ductility even at low temperatures; indium is soft and tough, suitable for most sealing materials under normal operating temperatures, but will break at -150°C.
VI HALBLEITERMATERIAL GmbH (VIMATERIAL) employs a stringent quality assurance system to ensure the reliability of our product quality. Strict quality control is implemented throughout the entire production chain, and for defective products, we strictly enforce the principle of rework and redo. Each batch is released only after passing detailed specification tests.
Every batch of our materials is independently tested, and, if necessary, we send samples to certified companies for testing. We provide these documents and analysis certificates with the shipment to certify that our products meet the required standards.
