Frequently Asked Questions
How Does Gold Compare to Other Metals in Terms of Conductivity?
Gold ranks third in electrical conductivity among metals, following silver and copper.
While not the most conductive, gold’s exceptional resistance to corrosion and tarnishing makes it invaluable in electronic applications.
Silver, though highest in conductivity, tarnishes easily, and copper, while efficient and economical, oxidises over time.
Gold’s unique combination of reliable conductivity and corrosion resistance guarantees consistent performance in critical electronic components, particularly in harsh environments.
What Alternatives Exist for Gold in Technological Applications?
Several viable alternatives to gold exist in modern technological applications.
Nickel-based alloys offer cost-effective solutions with comparable electrical contact resistance, while copper’s high conductivity makes it ideal for circuit boards and power systems.
Palladium and silver provide excellent conductivity for specialised electronics, particularly in automotive and medical devices.
Emerging alternatives include composite materials combining base metals, and promising developments in graphene-based technologies continue to advance the field.
Can Recycled Gold Maintain the Same Quality for Technological Use?
Recycled gold can absolutely maintain the same quality as newly-mined gold for technological applications.
Through sophisticated refining processes like electrolysis and the aqua regia method, recycled gold achieves identical purity levels. Quality control systems and accredited refineries guarantee the metal meets strict industry standards.
The inherent properties – malleability, conductivity, and corrosion resistance – remain unaffected during recycling, making it equally suitable for demanding technological uses.
How Much Gold Is Typically Used in Modern Smartphones?
Modern smartphones contain between 7 and 34 milligrams of gold, which equates to roughly 0.007 to 0.034 grams per device.
This precious metal is mainly found in circuit boards, connectors and bonding wires. While the amount seems miniscule, it’s essential for the phone’s functionality due to gold’s superior conductivity and corrosion resistance.
With global production reaching 1.5 billion smartphones annually, this adds up to approximately seven metric tonnes of gold usage.
Why Hasn’t Silver Replaced Gold in Most Technological Applications?
Despite silver’s superior conductivity and lower cost, it hasn’t replaced gold in technology due to several critical limitations.
Silver’s tendency to tarnish and oxidise compromises long-term reliability, particularly in sensitive applications like medical devices and aerospace components.
Gold’s exceptional corrosion resistance, durability under extreme conditions, and biocompatibility make it irreplaceable in high-stakes technological applications where failure isn’t an option, despite its higher cost.
