GalliTHERM®的类型
我们有三种镓基材料：
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
液态金属浆料
用于高粘度镓基材料
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
镓预型件
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.
液态金属 (LM) 瓶坯
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.
液态金属浆料
液态金属浆料（LMP）是一种基于液态金属的下一代散热浆料，专为高性能计算半导体应用（包括 CPU、GPU 和 MCM）中的高级热管理而设计。它类似于标准的镓基液态金属。通过专有工艺和某些添加剂，它的粘度得到了改善，形成了一种均匀的可抛弃/可喷射导热膏，可用于大批量应用。
特点
液态金属领导者提供稳定的镓金属供应，确保您的材料可用性。
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.
熔点为 29.76°C
当镓与铟、锡或锌等金属结合时，会形成在室温下保持液态的合金。
无毒合金
镓基液态金属不会蒸发，也不会被吸入。
极具攻击性
镓基液态金属不得与任何铝制部件接触。
多样化应用
这包括热界面材料（TIMS）、可拉伸和可穿戴电子设备、软机器人技术、可穿戴医疗设备和无汞温度计。
