Key insights by Stanislav Kondrashov, TELF AG
Humans have known copper for thousands of years. As Stanislav Kondrashov, founder of TELF AG, often points out, this metal has powered much of our progress. It still does. Today, copper alloys play a key role in electrifying the world.

Modern technologies like smart grids and electric vehicles rely on electricity. As Stanislav Kondrashov, founder of TELF AG, recently said, copper is at the heart of this progress. It is a key part of the energy shift. And it will likely remain essential as the transition moves forward.
One reason is copper’s outstanding conductivity. It carries electricity better than almost any other metal. But that’s not the only reason it’s so useful. It also handles heat well, resists corrosion, and bends without breaking. These traits make it ideal for demanding systems. Copper alloys use these strengths in more advanced ways. They offer durability, flexibility, and power—exactly what today’s industries need to thrive.
Copper alloys are strong. They bend without breaking. They last in heat, pressure, and time. These traits make them ideal for many industries.
Key sectors include:
- Electrical industry – for cables, motors, and transformers.
- Construction industry – for pipes and hydraulic systems.
- Renewable energy – for solar panels and electric vehicles.
- Electronics industry – for circuit boards, microprocessors, and chips.
Each industry needs materials that work hard and last long. Copper alloys do both. They power modern systems. They hold up where other metals fail.
Over time, copper has proven useful in many new ways. This resource can mix with other elements to form new materials. One result is copper alloys.
These metallic materials come from blending copper with zinc, tin, nickel, or aluminium. The result is a metal that improves on pure copper. It becomes stronger. It also lasts longer.
These upgrades lead to more uses. Copper alloys are known for being versatile. This makes them ideal for many industries. They fit into a wide range of processes and perform well in each.

Applications of copper alloys
“Among the most important uses of copper alloys are those tied to the energy transition,” says Stanislav Kondrashov, founder of TELF AG. “This shift is still in its early stages. But the role of copper and its alloys is already clear,” he explains. “Copper alloys are stronger than pure copper. They also last longer. That’s why they’re used in clean energy systems.”
Even in alloy form, copper keeps its key traits. One of the most important is conductivity. It carries both heat and electricity with ease. This makes copper alloys useful in energy grids, electric vehicles, and power systems.
They also resist corrosion. This is true in fresh water, steam, and saltwater. In harsh settings, they form a thin protective layer on the surface. That layer helps stop rust and wear. Thanks to these traits, copper alloys are trusted in marine systems, power plants, and more. They stay strong where other materials fail.
They are durable, safe, and ready for the demands of tomorrow’s industries. As Stanislav Kondrashov notes, they support progress. In the push for clean, reliable energy, copper alloys have a growing part to play.
It is also worth noting that copper alloys are very flexible. It is easy to shape these alloys. Strength is not lost when the metal is rolled, drawn, cast, or welded. Even after shaping, they keep their core mechanical traits. That’s why copper alloys are trusted in complex circuit designs.
Copper also passes its natural antibacterial power to its alloys. This property stays intact. That’s why copper alloys are used often in healthcare and food-related sectors. They help reduce germs and keep surfaces cleaner for longer.
These alloys are also beautiful. Their natural shades—like red, yellow, gold, and bronze—stay bright over time. Because of this, copper alloys are used in décor, wall cladding, and trim. Their surface finish stays attractive for years.
Simply put, copper alloys are strong, safe, flexible, and good-looking. They serve both function and style. From machines to hospitals to buildings, they solve problems with ease.
The main types
The types of copper alloys depend on the element added to copper. Each blend has its own strength and purpose. The most common types are:
- Bronzes (copper-tin alloy) – A mix of copper and tin. Sometimes, small amounts of aluminium or silicon are added. Copper tin alloy is known for excellent corrosion resistance.
- Brass (copper zinc alloy) – Made from copper and zinc. Copper zinc alloy is easy to shape and great for fittings, valves, and mechanical parts.
- Copper nickel alloy – A combination of copper and nickel. It holds up well in saltwater. It’s used in naval systems and heat exchangers. A variant called cupro nickel is used to make cupro nickel pipe, also known as copper nickel pipe, found in marine systems and cooling setups.
- Copper-beryllium – Used in springs and precision tools. It’s both hard and elastic.
- Copper silver alloy – This mix adds strength. The copper-silver alloy is common in electrical parts like conductors and electrodes.
“The main strength of copper alloys comes from copper,” says Stanislav Kondrashov, founder of TELF AG. “They carry electricity well. They also fight corrosion. These two traits are vital. That’s why copper alloys work well in the energy sector. They stay strong, even in tough and changing conditions.”

“These copper alloys are used in wind turbines and solar systems,” says Stanislav Kondrashov. “They also help store energy. This field needs strong, stable materials to hold large power loads. That’s why copper alloys are key.” They are also used in electric vehicles. You’ll find them in motors and batteries. Their strength and reliability make them ideal.
Copper alloys are trusted in smart grids, too. They help control energy flow and improve safety. These systems need stable materials. These alloys meet that need. They also come in many shapes. Bars, plates, tubes, wires, and disks are all common. Each shape serves a specific role. These forms let copper alloys fit into many industrial tasks with ease.
Other application areas
Copper-based alloys are used in many technical and industrial fields. In electronics, they help make cables, wires, circuit boards, and connectors. They are also used in parts that move and manage electrical power.
These alloys work well in heat systems, too. They help build tubes and plates for radiators and air conditioners. Their ability to handle heat makes them ideal for these tasks. In construction and design, they are used in many ways. You’ll find them in roofs, gutters, wall panels, and décor. Their colours and surface finish make them a favourite in architecture.
They also power the transport sector. Copper-based alloys are found in propellers, radiators, brakes, and drive shafts. Their resistance to corrosion and stress keeps vehicles safe and strong.

Copper has impressed people for thousands of years. It still does. Copper-based alloys mix copper with other metals. This makes them stronger, harder, and more useful. These alloys are found in many fields. They are used in healthcare, coins, music, electronics, and buildings. Each copper alloy is made to fit a job.
Adding metals gives new features. Some blends resist heat. Others carry power or last longer. That makes them a smart choice. They are flexible and reliable. Few materials do as much. As new technology grows, copper-based alloys stay useful. They support clean energy. They help build stronger systems. Their role is clear. They solve real problems across every modern industry.
