Precious metals in industrial manufacturing

Precious metals are not only valued for investment or aesthetics but are also a fundamental group of materials in many modern industrial sectors thanks to their high chemical stability, durability, and outstanding technical properties. Through this article, DC helps you understand the definition of precious metals, their common types, and their applications in industrial manufacturing.

I. What are precious metals?

Precious metals are a group of rare, high-value metals known for their resistance to oxidation, chemical durability, and long-term stability in various environmental conditions. These properties allow precious metals to maintain their quality almost unchanged over time, unlike most common metals.

In industrial manufacturing, precious metals are not only valuable in terms of material worth but also play a critical role in ensuring system safety, precision, and operational stability. Even a slight deviation in composition or purity can lead to significant technical and cost risks.

II. Common types of precious metals

1. Gold (Au)

Gold is highly valued for its resistance to oxidation and stable electrical conductivity over time. It is one of the rare metals that can maintain its surface quality and electrical properties almost unchanged in harsh working environments.

In high-precision technical systems, gold is commonly used for electrical contacts, microelectronic circuits, and precision components, where material stability directly determines operational quality.

2. Silver (Ag)

Silver has the highest electrical and thermal conductivity of all metals, minimizing energy loss during transmission.

In high-performance electrical and electronic systems, silver is a key conductive material, especially in high-power contacts, high-frequency circuits, and devices requiring fast response times.

3. Platinum (Pt)

Platinum stands out for its chemical durability, heat resistance, and structural stability under harsh operating conditions. It is one of the most technically durable precious metals.

For equipment operating in high temperatures and corrosive chemical environments, platinum is almost irreplaceable, especially in catalysts, sensors, and chemical reaction systems.

4. Palladium (Pd)

Palladium has strong catalytic activity and an excellent ability to absorb hydrogen, playing a central role in many modern chemical reactions.

In catalysis and exhaust treatment, palladium is a core material that optimizes reaction efficiency, reduces harmful emissions, and improves energy efficiency.

5. Rhodium (Rh)

Rhodium is known for its high hardness, wear resistance, and superior surface durability. It is a precious metal mainly used for protective coatings.

For components that must maintain long-term surface stability, rhodium is used to enhance durability, limit oxidation, and extend product lifespan.

6. Ruthenium (Ru)

Ruthenium features high hardness and good electrochemical stability, making it suitable for applications requiring high technical precision and long-term durability.

In microelectronics and precision components, ruthenium is used in thin-film resistors, capacitors, and technical coatings to ensure stability and operational reliability.

III. Functions of precious metals

Precious metals serve as fundamental materials for high-tech industries where precision and stability are vital. Thanks to their purity and ability to maintain physical properties over time, they help systems operate reliably and minimize technical risks.

Another important function of precious metals is their use as industrial catalysts. They enable chemical reactions to proceed faster and more efficiently without being consumed, thereby optimizing energy usage and production costs.

In addition, precious metals are applied in medical and biotechnology fields due to their high biocompatibility, non-reactivity, and long service life.

IV. Applications of precious metals in industrial manufacturing

1. In the electrical – electronics industry

Gold, silver, and ruthenium are used for plating electrical contacts, manufacturing semiconductor chips, and microelectronic components. With stable conductivity and oxidation resistance, precious metals ensure accurate signal transmission and minimize technical errors.

For high-end electronic equipment, precious metals are almost a mandatory standard to maintain long-term reliability.

2. In electroplating and surface treatment

Precious metal plating increases corrosion resistance, wear resistance, and extends product lifespan. Gold, silver, palladium, rhodium, and ruthenium coatings all provide high technical value.

They are considered the “final protective shield” for components against harsh working environments.

3. In the chemical and environmental industry

Platinum, palladium, and rhodium are central to industrial catalytic systems. They support exhaust treatment, reduce harmful emissions, and enhance chemical reaction efficiency.

Many modern chemical processes cannot operate effectively without precious metals.

4. In the medical and biotechnology industry

Precious metals are used in biomedical devices, dental restorations, and precision surgical instruments. Their high biological stability ensures long-term safety for the human body.

5. In the energy and green technology industry

Precious metals play an important role in fuel cells, hydrogen technology, and clean energy conversion systems. They are key materials for the global trend toward sustainable industrial development.
