GalliTHERM®系列
As a global leader in metal-based thermal interface materials, Indium Corporation brings decades of expertise as a trusted supplier of gallium-based materials. With high quality and lot-to-lot consistency built into every step of our controlled production process, we ensure reliable performance—especially due to Gallium-based alloys requiring careful handling as Class 8 (corrosive) materials. Leveraging our extensive expertise, we ensure safe and compliant packaging and transportation—by air, highway, rail, or sea—meeting all regulatory standards and delivering securely to your facility.

GalliTHERM®的类型
We have three types of gallium-based materials:
液体金属
或在室温下呈液态的合金
相变金属合金
在室温下为固体
Liquid Metal Pastes
for use with high-viscosity gallium-based materials
液体金属
These are pure metals or metal alloys that remain liquid at room temperature, with melting points ranging from 7.6°C to 17°C. The primary element in these alloys is gallium, which is often combined with other elements such as indium (In), tin (Sn), or zinc (Zn). All liquid metals from Indium Corporation are RoHS-compliant, non-toxic, and safely transported worldwide, adhering to global shipping requirements.
相变金属合金
Gallium Preforms
Gallium is a soft, silvery-white metal notable for its low melting point of about 29.76°C. For that reason, producing gallium as a preform is highly challenging. Indium Corporation has a proprietary process of producing pure gallium and gallium alloy preforms in variety of shapes and sizes with thicknesses down to 50 μm.
Liquid Metal (LM) Preforms
Indalloy®300E (Ga78.6/In21.4) is a eutectic gallium-indium liquid metal alloy known for its high thermal conductivity—the highest of any liquid metal. Adding more indium increases thermal conductivity, but the alloy remains liquid or pasty until the ratio reaches In97/Ga3, at which point it solidifies near indium’s melting point (156.6°C). To assemble, start by placing indium preforms on the heat source, ensuring the entire surface is covered. Next, place gallium preforms on top, ensuring they do not need to cover the entire indium surface.
Liquid Metal Pastes
Liquid Metal Paste (LMP) is a next-generation, liquid metal-based thermal paste engineered for advanced thermal management in HPC semiconductor applications, including CPUs, GPUs, and MCMs. It is similar to standard gallium-based liquid metals. Through a proprietary process and certain additives, the viscosity is modified to form a homogeneous dispensable/jettable thermal paste for use in high-volume applications.
特点
Liquid metal leaders providing a stable supply of gallium metals ensures your material availability.
Indium Corporation has been manufacturing and supplying gallium-based liquid metals for more than 60 years, with low and high-volume production available in the U.S. and Asia.
Melting Point of 29.76°C
When gallium is combined with metals such as indium, tin, or zinc, it forms alloys that remain liquid at room temperature.
无毒合金
Gallium-based liquid metals do not evaporate and cannot be inhaled.
极具攻击性
Gallium-based liquid metals should not be in contact with any aluminum parts.
Diverse Applications
That includes thermal interface materials (TIMS), stretchable and wearable electronics, soft robotics, wearable medical devices, and mercury-free thermometers.
