Dr. Wade A. Jensen explores the concept of temper designations and their impact on the properties of metals. Deringer-Ney, a manufacturer of precious metal alloys, uses temper designations to describe the condition of the material and its resulting microstructure and properties.

This article explains switch bounce, a phenomenon where switch contacts momentarily separate after closing due to their own rebound. This bouncing creates electrical arcs that erode the contacts and shorten their lifespan.

Deringer-Ney’s design engineers leveraged Finite Element Analysis (FEA) to optimize a bi-metallic wiper with a precious metal contact surface and a non-precious metal body. This approach offered the combined benefits of high electrical performance and cost efficiency.

This article explores the effects of alloying and microstructural factors on electrical conductivity in metals, detailing the role of thermal scattering, alloy scattering, and interface scattering in influencing conductivity levels. By understanding these factors, high-performance alloys can be designed with the desired hardness and conductivity properties to suit specific applications. Deringer-Ney offers a range of noble alloys with customizable properties to cater to specific client needs, enabling them to develop high-quality products tailored for their application requirements.

The Hume-Rothery rules are a set of guidelines that help predict the solubility and behavior of alloy systems. The rules state that solvent and solute atoms should have similar atomic radii, similar crystal structures, and comparable valencies for maximum solubility. Additionally, the electronegativity difference should approach zero for greater solubility. These rules help engineers design innovative alloys for various applications.
