The manufacture of high purity specialty metals and elements for special applications has been a major activity of Alfa Aesar for many years. We have expertise in developing products of exceptionally high purity.
As a specialty metals manufacturer, we are accustomed to providing custom fabrication and special packaging services to meet your specific requirements. All products ship with a comprehensive certificate of analysis and material safety data sheet. We recognize that prompt delivery is crucial, so we strive to always meet promised delivery dates.
Pure metals and pure elements from Alfa Aesar are used in applications such as single crystal growth, fundamental materials research, photovoltaic technology, and the manufacture of sputtering targets and vacuum evaporation source materials. With the advent of advanced materials research for the microelectronics industry, Alfa Aesar introduced the Puratronic® line of base metals and Premion® precious metals. We also offer a full range of rare earth metals in various forms, including the REacton® brand line. Rare earth metals are typically packaged under inert gas such as argon or in mineral oil to prevent tarnish and corrosion.
Seven types of thermocouple wires are available from stock and cut to length for a variety of applications and temperature ranges. We carry certified type S, type R, type B, type J, type K, type T, and type E wires.
A selection of ceramic products in a variety of shapes and materials is available, including high purity alumina (Al2O3), zirconia (ZrO2) and other oxide, nitride and carbide materials.
Our ceramics provide advantages such as extreme purity, extreme resistance to corrosion, good thermal conductivity, stability in oxidizing and reducing atmospheres, ultra high vacuum resistance, stability at high temperatures, and a good resistance to thermal shock.
We offer a variety of materials for coating, photonic, and electronic applications, including single crystal oxides, optical materials, superconducting powders, metal crystals, coating materials and semiconductor materials.
Alfa Aesar offers a wide variety of high purity precious metal products (gold, iridium, osmium, palladium, platinum, rhodium, ruthenium, and silver) in a variety of forms: wires, foils, powders, and more.
