Properties
Conductivity, corrosion resistance, reflectivity, density, alloys and thin-film logic.
Gold beyond jewelry and bullion
Why industry uses tiny amounts of gold in critical places.
Gold is rarely the cheapest bulk material. Its value comes from stable electrical contacts, corrosion-resistant surfaces, fine bonding, specialized optics, surface chemistry and recoverability.

Use the property where it matters
Electronics
Contacts, connectors, PCBs, semiconductors, RF, telecom and smart devices.
Manufacturing
Plating, vacuum deposition, thin films, selective coatings and quality control.
Aerospace & optics
Spacecraft thermal control, avionics, optical coatings and photonics.
Sensors & nano
Sensors, biosensors, nanoparticles, optical sensing and catalysts.
Recycling & supply
Professional refining, e-waste, manufacturing scrap and circular gold.
Rebuilt for depth
The legacy WordPress database repeated aerospace, contacts, coatings, medical devices, telecom, sensors and semiconductor topics under many similar titles. The replacement consolidates those themes and adds stronger material-selection, quality and recycling context.
No DIY refining chemistry
Refining, plating and precious-metal recovery can involve hazardous chemicals and controlled industrial processes. Those subjects stay conceptual.
