This newsletter marks the final installment of our series on copper.

In the first part, we explored the origins of copper and its role in human civilization. The second part highlighted various ways copper is used in our everyday surroundings. Today, we’d like to bring the topic closer to home by focusing on the role copper plays in modern industry.

You can revisit Parts 1 and 2 from earlier issues by clicking on the red text at the top.

Although copper's origins are ancient, its use continues to be current.

Used for tools and ornaments thousands of years ago, copper remains an indispensable metal in industrial settings even today.

This isn't just because it has a long history. Copper excels at conducting heat and electricity, is resistant to oxidation and corrosion, and is ductile yet strong. These qualities also make it an ideal base for alloys with a variety of metals.

The most representative among them is bronze. Bronze is an alloy of copper mixed with tin (Sn), offering excellent strength and wear resistance, easy machinability, and reliable performance even in environments with frequent mechanical friction.

Bronze, an alloy of copper and tin, offers superior mechanical strength and excellent resistance to wear, ensuring stable performance even in high-friction environments. Thanks to its superior heat and wear resistance, self-lubricating properties, and precision machinability, it is optimized for machine parts operating in extreme conditions such as construction machinery, press and mold machines, and heavy equipment.

More than just a material, copper alloys especially bronze play a critical role in determining performance.

Thus, copper alloys, working alongside embedded lubricants within bearings, play a crucial role as a core material in reducing friction and minimizing wear.

At the core of SGO’s flagship product, oilless bearings, is a robust copper alloy particularly bronze-based. These bearings are built to withstand extreme conditions maintaining smooth, stable motion under high loads, friction, and heat, even without oil or grease. That’s why durable copper alloys like bronze are a preferred choice.

SGO’s oilless bearings deliver exceptional performance and long service life in demanding applications such as industrial machinery, construction equipment, and automation systems where extreme conditions, high precision, and durability are essential.

The key to the outstanding durability and performance of SGO’s oilless bearings even in the harshest environments lies in the powerful synergy between high-performance copper alloys and SGO’s proprietary engineering.

Once prized for tools and artistry in ancient times, copper today finds renewed purpose refined by precision engineering at the core of SGO’s bearings.

Copper continues to quietly power industry, enable innovation, and build the foundation for a better future right here, right now.

At SGO’s Technology Research Center, copper is seen not just as a metal of the past, but as a key to building a sustainable and high-tech future through continuous innovation.

Moving forward, SGO will continue to expand the possibilities of copper and strive even harder to develop excellent products.

In this series, we explored copper’s rich history, its diverse forms, and its vital role in modern industry.

We hope this Copper Series has inspired you to see the true depth and value of this extraordinary metal.

Stay tuned to the SGO newsletter as we return with new series and even more exciting stories. :D
