Indium Tin Alloy

Indium Tin Alloy Pellets is an alloy pellet composed of indium and tin. It combines the properties of indium and tin with fine particles, which plays an important role in many fields such as electronics, soldering, coating, etc. It is a material with good electrical conductivity, low melting point and other advantages.

Characteristics

Density: Moderately dense at approximately 7.30g/cm³, this characteristic gives Indium-Tin alloy particles an advantage in applications where weight and volume are important.

Melting point: Low, typically around 118°C-120°C. The low melting point makes it suitable for use at low temperatures. The low melting point allows it to melt at low temperatures, making it easy to process and mould, and it is widely used in electronic packaging, temperature control and other fields.

Appearance: usually silver grey, with a metallic luster.

Resistivity: about 0.147µΩ・m, with good conductivity, so it can be used as a conductive material or electrode material in the field of electronics, electrics and other areas that require conductivity.

Thermal conductivity: approx. 34W/m・K, high thermal conductivity, able to transfer heat quickly, so it has potential for use in thermal management, heat dissipation, and other fields, for example, it can be used to make heat sinks or thermal interface materials.

Indium tin alloy coating can increase the reflectivity or transmittance of optical elements and improve optical performance, for example, it is used in camera lenses, telescopes and other optical equipment.

Liquid Crystal Displays: In liquid crystal displays (LCDs), indium tin alloy particles can be used to make transparent conductive electrodes, which control the arrangement of liquid crystal molecules and the transmission of light, thus realising the display of images.

Thermal Management Field:

Thermal interface materials: Due to their high thermal conductivity, indium tin alloy particles can be used as thermal interface materials to fill in between electronic components and heat sinks, improving the efficiency of heat transfer, lowering the operating temperature of electronic components, and extending their service life.

Temperature sensors: Using the characteristic of its resistance changing with temperature, it can be used to make temperature sensors. In some occasions that require high precision of temperature measurement, such as medical equipment, industrial automation and other fields, indium tin alloy temperature sensors have important application value.

Mould manufacturing field:

Mould forming: the low melting point of indium-tin alloy particles makes it possible to use it as a forming material for making moulds. For example, in the manufacture of some complex shaped parts, the use of indium tin alloy moulds can reduce the difficulty and cost of mould manufacturing, while improving production efficiency.

Mould Repair: Indium tin alloy particles can be used to repair moulds when they are partially damaged or worn. Indium tin alloy particles are melted and filled into the damaged area, and when cooled and solidified, the shape and size of the mould can be restored to prolong the service life of the mould.

Medical field:

Radiotherapy: In radiotherapy, indium tin alloy can be used to make radiation shielding materials to protect normal tissues from radiation damage. In addition, it can also be used to make carriers for radiopharmaceuticals to improve the targeting and therapeutic effects of the drugs.

Medical devices: For example, in some medical testing equipment, indium tin alloy particles can be used to make electrodes or sensors for detecting physiological signals of the human body, such as ECG and EEG.
