Indium Rod

Formula: In

Form: Rod

Material: Indium

CAS Number: 7440-74-6

Commodity: Metals

Purity: 99.999%

We offer Indium Rods in a wide choice of 39 variations to accommodate different sizes and diameters. As a soft, ductile metal, indium exhibits properties such as malleability, corrosion resistance and a low melting point. These attributes make it valued for applications in solders, thin films and low-temperature alloys. The diverse range of Indium Rods we provide allows for the selection of the optimal size and form for electronics and optics as well as various research and development projects.
