Gold Finish Secret Contact pads and edge connectors on many boards carry a gold finish only a fraction of a micron thick, over a nickel layer. Gold never tarnishes, so contacts stay clean, while the nickel stops gold from diffusing into the copper beneath. A whisper
Lead Sheath Cables For much of the twentieth century, underground power and telephone cables wore a seamless lead sheath. Extruded directly over the cable core, the soft, corrosion-resistant jacket kept moisture from the paper insulation, and some old lead-sheathed cables still serve today. Have any Questions?
Most Recycled Product In the United States about 99 percent of lead-acid batteries are recycled, one of the highest rates of any consumer product. Lead melts at a modest 327 degrees Celsius and can be remelted without losing quality, so scrap supplies a large share of
Fuse Wire Safeguard Traditional rewirable fuse wires were often tin-lead alloys. Their low melting point is the whole idea: if current climbs too high the wire melts and breaks the circuit, saving the appliance. A fuse protects by sacrificing itself, a tiny metal bodyguard for the
Lead Dated Earth In the 1950s geochemist Clair Patterson used lead isotopes from the Canyon Diablo meteorite to calculate Earth’s age at about 4.55 billion years. Lead is the final stable product of uranium and thorium decay, so its isotope ratios act as a natural clock

Lead-Free Zinc Dilemma A tin-zinc mix of about 91 percent tin melts near 198 degrees Celsius, close to classic tin-lead solder at 183. That makes it an attractive lead-free idea, but zinc oxidises so eagerly that it needs special fluxes or protective gas. Good on paper,
Pliny’s Ancient Solder Roman writer Pliny the Elder described lead-tin solders almost two thousand years ago, including a two-to-one lead-tin mix called tertiarium. Roman plumbers used such alloys on pipe seams. The English word solder itself comes from the Latin solidare, meaning to make solid. Have
