Industrial Silver
Also: Technical silver, Silver commodity
Industrial silver refers to silver used as a raw material in technical and industrial applications, as opposed to investment or jewellery silver.
Industrial silver is the largest demand sector by volume in the global silver market. While investors buy silver as a store of value or inflation hedge, industry permanently consumes silver in products – a large proportion of which cannot be economically recovered. This structural consumption demand makes industrial silver an independent price driver that operates independently of investor sentiment.
Properties that make silver indispensable in industry
Silver possesses a combination of physical properties that no other metal can fully replicate:
- Highest electrical conductivity of all known metals (63 MS/m), surpassing even copper
- Highest thermal conductivity of all metals
- Antimicrobial effect – effective against bacteria, viruses, and fungi without developing resistance
- High reflectivity in the visible and infrared light spectrum (> 95 %)
- Chemical resistance to many alkalis and weak acids (but dissolves in nitric acid and hot sulphuric acid)
Compared to copper – the next most affordable conductor – silver is more expensive, but cannot be substituted in many high-performance applications.
The most important application areas
| Sector | Application | Characteristic |
|---|---|---|
| Photovoltaics | Silver paste for solar cell contacts | largest single consumer, growing strongly |
| Electronics | Conductor tracks, contacts, solder | high purity requirement (≥ 999) |
| Electric mobility | Battery management, switches, sensors | growth driver from 2025+ |
| Chemicals | Catalysts (e.g. ethylene oxide synthesis) | silver barely substitutable |
| Medical | Wound dressings, catheters, implants | antimicrobial effect |
| Photography | Silver halides (X-ray, specialist photo) | declining, but still relevant |
| Mirrors / optics | Coatings, telescope mirrors | high reflectivity |
Photovoltaics as the dominant driver
The solar sector has developed into the most important industrial consumer since 2010. Every solar cell contains silver paste to contact the silicon wafers. With the global expansion of renewable energy, the solar industry's demand for silver increases year after year – despite advances in material savings per cell (thrifting). According to Silver Institute estimates, the photovoltaic sector alone could require around 200 million ounces annually by 2030.
Melt value and price determination
Industrial silver is predominantly traded as fine silver (999/1000) – in the form of LBMA-certified Good Delivery bars (1,000 oz), granules, or powder. The price is based on the current spot price, which is determined daily at the COMEX in New York and via LBMA fixing in London. Those wishing to calculate the melt value of silver objects can use the melt value calculator.
For historical price development – and thus the long-term influence of industrial demand on the silver price – the historical precious metal prices provide a good reference.
Recycling and circular economy
A portion of industrial silver is recovered (secondary silver): from photographic chemicals, electronic scrap, catalysts, and dental alloys. The recycling rate varies considerably by sector – while up to 90 % is recovered from photography and chemicals, silver from solar cells or solder joints is barely economically recoverable. Globally, recycling covers around 15–20 % of total demand.
In brief
Industrial silver is not a niche topic: more than half of global silver demand comes from technical applications, with a rising trend. Anyone wishing to assess the silver price over the long term should consider industrial demand – particularly from the solar industry and electric mobility – as an independent price factor.
