Tin
High-Purity Tin
High-purity tin products offer additional benefits through the absence of impurities. High-purity tin is attractive for specialized applications, whenever the presence of impurities is detrimental for the end-use, such as desired film quality in high end deposition applications and electronic performance that is affected by the presence of undesirable impurities.

Product Overview
Wide Range of Sizes
Indium Corporation’s metal ingots are available in various weights, shapes, and sizes to meet specific application needs.
Quality Assurance
Indium Corporation implements a robust quality management system with lot tracking, strict adherence to quality standards, and full compliance with customer requirements.
Controlled Impurities
Metallic impurities such as Ag, Al, Cu, and Zn are carefully controlled to low levels, ensuring the highest purity for critical applications.
Prevention of Tin Pest
High-purity tin is susceptible to tin pest—a phase transformation. We prevent this by controlling specific impurities, maintaining stability and reliability.
Features
Tin has been used as a material for bonding and soldering for centuries. But it is also used as the source material for the most advanced semiconductor processing fabs today: the latest generations of lithography tools use high-purity tin as the light source for the illumination of the masks used to pattern silicon wafers.
232°C
Pure tin melts at 232°C, while alloyed tin, like Sn60Pb40, melts at 183°C, ideal for bonding before lead-free electronics became standard.
13.2 nanometer
Tin is used as the light source in lithography tools, emitting a 13.2nm wavelength crucial for extreme ultraviolet (EUV) lithography in semiconductor fabs.
13.2°C
Tin undergoes a phase transition at 13.2°C, known as tin pest, affecting stability. Impurities like Bi, Pb, Sb must be controlled for reliable performance.
Low-Alpha Tin
Low-alpha tin is used in soldering and bonding near sensitive circuitry, where controlling impurity levels is key to preventing alpha radiation from flipping digital bits.
