As copper’s antimicrobial benefits spur new applications, the metal’s other properties are also worth reviewing. Along with strength, fatigue resistance, and ability to take a good finish, the primary selection criteria for copper and its alloys are electrical conductivity, thermal conductivity, corrosion resistance, color, ease of fabrication, and antimicrobial benefits.

Advancements in nanoscience are making it possible to metallically glue two solids together at room temperature, in air, and under a small amount of mechanical pressure. Metallic glues can serve as excellent conductors for heat dissipation and electrical current in electronic devices and also as leak-resistant seals for vacuum environments.

Beryllium won a lengthy competition as the material of choice for the mirrors on the James Webb Space Telescope, set to launch in 2018. This article documents the development history leading up to that decision. It took decades to perfect powder atomization and HIP'ing processes to make optical-grade beryllium components homogeneous, isotropic, polishable, thermally and dimensionally stable, and above all, predictable.

Durable polyimide parts that can withstand challenging aerospace environments mean longer service life, less maintenance, and smaller part inventories for aircraft fleet owners.
