Gallium Indium Eutectic is an electrically conductive fluid metal and it can be formed into metastable, non-spherical structures (e.g. cones, and filaments with diameters ≥1 mm). It has a high electrical conductivity (3.4x104 S∙cm-1) and its tendency to make low contact-resistance interfaces with a variety of materials. It is widely used as contact electrode in electrical characterization of thin film organic and semiconductor devices. 

The weight ratio of gallium and indium can be customized upon request. We also can supply Gallium Indium Tin alloy with customized ratio. Please contact us at 

Notes: More detailed product information including SDS, certificate of analysis (COA), lead time and volume pricing are available upon request.

Shipping and handling: This material is classified as a hazmat and requires special packaging and shipping to comply with regulatory requirements. Please contact us for specific details with shipping and handling.
