Electronics
Manufacturers of electronic devices and components rely on palladium and ruthenium for their conductivity and corrosion resistance, using both metals in electrical contacts, connectors and multilayer ceramic capacitors.

Overview
The electronics industry designs and manufactures the devices and components that make up computers, phones, appliances and industrial control systems — a category broad enough to include everything from a smartphone assembled in a single factory to the printed circuit boards and semiconductor chips supplied by hundreds of specialized companies feeding into a single finished product. It's one of the most globally distributed supply chains in manufacturing: a typical device might combine chips designed in one country, fabricated in another, assembled with components sourced from a dozen more, and finally put together at a contract manufacturer before shipping worldwide. That fragmentation makes the industry unusually sensitive to disruption at any single point in the chain, which is why a shortage of one component, like semiconductor chips during the pandemic, can halt production of finished goods across completely unrelated industries.
Key Metals & Materials Used
Gold's excellent conductivity and resistance to corrosion make it the standard for plating connectors, circuit board contacts and the bond wires inside chips, even though the amount used per device is tiny. Silver, an even better conductor, is used in circuit board pathways, switches and contacts, and the electronics industry is one of the largest single consumers of silver worldwide by volume even though the value per device is modest. Copper forms circuit board traces and wiring throughout virtually every device. Platinum group metals, particularly ruthenium, are used in hard-disk-drive data storage media and specialized electronic components, while rare earth elements go into the magnets found in speakers, vibration motors and hard drives.
How the Industry Operates
Semiconductor chips, the industry's foundational component, are fabricated in specialized plants that etch circuit patterns onto silicon wafers through hundreds of precise chemical and lithographic steps, a process concentrated in a small number of countries given the extraordinary cost of building a modern fabrication facility. Printed circuit boards are manufactured separately, then populated with chips, resistors, capacitors and connectors through automated surface-mount assembly. Contract manufacturers, most notably in East Asia, then assemble these components into finished products under contract to brand owners who design and market the devices but often don't operate their own factories at all. This division between design, component fabrication and final assembly, spread across many countries and companies, is what makes the electronics supply chain both remarkably efficient and unusually fragile to disruption.
Byproducts & Waste Streams
Electronic waste is the industry's most visible downstream problem: discarded phones, computers and appliances form one of the fastest-growing waste categories worldwide, containing recoverable gold, silver, copper and rare earth elements alongside hazardous materials like lead solder and flame retardants that require specialized handling. Chip fabrication itself generates chemical waste streams from the etching and cleaning processes, along with significant water and energy consumption per wafer produced. A growing recycling industry has developed specifically around e-waste, since the concentration of precious metals in circuit boards and connectors can make recovery more cost-effective per tonne than mining ore, though only a fraction of global e-waste is currently processed through formal recycling channels rather than informal or unregulated disposal.
Who It Serves
Consumer electronics brands buy chips and components to build phones, laptops, TVs and wearables sold directly to the public. Automakers have become major electronics customers as vehicles add more sensors, infotainment systems and, in electric vehicles, sophisticated power electronics. Telecommunications companies buy networking equipment and infrastructure electronics to build and maintain communication networks. Industrial and medical equipment makers depend on specialized electronic components for control systems, sensors and diagnostic devices, while data centers and cloud providers are major buyers of server-grade chips and storage electronics, a segment that has grown sharply alongside AI computing demand.
Role in Everyday Life
It's hard to name a part of daily life the electronics industry hasn't touched — phones, laptops, cars, kitchen appliances, medical devices, payment cards and light switches all rely on components this industry designs and builds. The pace of product cycles, often refreshed annually for consumer devices, shapes how often people replace working electronics rather than repair them, which is part of why e-waste has grown into such a large environmental issue. Beyond individual devices, the chips this industry produces increasingly sit behind services people don't think of as electronics at all — traffic lights, hospital equipment, banking systems — making reliable electronics manufacturing a quiet dependency running under nearly every modern convenience.

AI Chip Boom Fails to Lift Gold Demand, World Gold Council Finds
Gold used in electronics held flat at 323 tonnes in 2025 even as AI chip demand surged, the World Gold Council says. Manufacturers cutting gold from less critical components offset the new demand from advanced chips and data-centre gear.
Myanmar's Tungsten and Tin Shipments to China Surge as War-Zone Mines Restart
Tungsten carbide tooling and tin solder are core electronics manufacturing inputs, and rising Myanmar-sourced ore easing Chinese supply has coincided with tungsten prices falling from their March 2026 peak, though the supply remains tied to conflict-zone mining that can be disrupted without warning.
