📖 Über Zinc
The 24th most abundant element in Earth's crust and essential for human health, supporting over 300 enzymes and the immune system. Zinc deficiency affects about 2 billion people worldwide. Galvanizing (coating steel with zinc) is one of the most important corrosion protection methods, extending the life of steel structures dramatically.
🔧 Verwendungen und Anwendungen
- Galvanizing steel against corrosion
- Brass alloy (copper + zinc)
- Dietary supplements and immune support
- Sunscreen (zinc oxide)
- Batteries (zinc-carbon, zinc-air)
💡 Wusstest du?
Fakt: The US penny has been 97.5% zinc with a thin copper coating since 1982. Before that, pennies were 95% copper. The switch was made because copper became too valuable - the metal in older pennies was worth more than one cent.
