Description

Discover the fascinating world of liquid metal with our GaInSn eutectic alloy - a gallium-indium-tin blend that's liquid at room temperature.

GaInSn is composed of 68.5% gallium, 21.5% indium, and 10% tin by weight, with a melting point of approximately 10°C (50°F). This means it remains in a liquid state under normal room conditions - no heating required.

This offering is perfect for makers, engineers, educators, and science enthusiasts. GaInSn has a density of around 6.4 g/cm³, making it noticeably heavier than water but easy to handle in small quantities. It is supplied in an HDPE bottle.

The alloy will typically arrive in liquid form. If it has solidified due to cold temperatures during shipping, simply warm the bottle gently in your hands or place it in warm water and it will liquefy.

Key Features

Low Melting Point: Liquid at room temperature (10°C (50°F) melting point)
Safe and Non-Toxic: A safer replacement for mercury in many applications.
High Thermal Conductivity: Excellent heat transfer properties (~16.5 W/mK).
Versatile: Suitable for thermal management, electronics, and scientific experimentation.
Electrically Conductive: Good electrical conductivity (~3.46 × 10⁶ S/m).

Applications

Heat Transfer: Ideal as a thermal interface material between CPUs/GPUs and heatsinks for superior cooling performance. 
Electronics and Robotics: Used as a flexible, self-healing conductor in soft robotics and stretchable electronics.
Educational Tool: Demonstrate liquid metals, density, thermal conductivity, and alloy properties.
Scientific Research: Applications in thermometers, sensors, and as a non-toxic mercury replacement.

Please Note

GaInSn can stain or corrode certain metals, particularly aluminium - avoid direct contact with aluminium components. Handle with care and wash hands after use. Embrace the future of liquid metal technology with our GaInSn eutectic alloy!
