Tungsten vs Beryllium Copper – What’s the Difference

Tungsten vs Beryllium Copper

Tungsten and Beryllium Copper are the strongest and most durable metals used in various industrial applications. Both materials exhibit excellent mechanical and electrical properties but differ in many ways. If you work in the manufacturing or engineering industry, it’s important to understand the differences between tungsten and beryllium copper to choose the best material for your project. In this blog post, we will discuss the properties of tungsten and beryllium copper, their applications, and their differences.

What is Tungsten?

Tungsten is a naturally occurring element in trace amounts within the Earth’s crust. It is known as one of the densest and strongest metal elements, with a density about 1.7 times greater than steel. This makes it ideal for high-strength applications like cutting tools, aircraft components and ballistic armour. Furthermore, tungsten has an extremely high melting point of over 3400°C (6192°F), making it essential for certain manufacturing processes involving extreme heat conditions, such as arc welding and rocket motor igniters. Finally, its extraordinary resistance to chemical corrosion makes tungsten alloys perfect coatings for machine parts exposed to harsh environments or used in corrosive atmospheres.

What is Beryllium Copper?

Beryllium Copper is an alloy of copper and 0.5 to 3% beryllium. It offers high electrical and thermal conductivity, good formability, machinability, corrosion and wear resistance, and a high strength-to-weight ratio. Its unique properties make it ideal for high-pressure applications such as aircraft components or computer connectors. Additionally, its non-magnetic nature makes it attractive for medical instruments such as X-ray machines or implantable pacemakers where magnetic interference can be hazardous. Its malleability allows it to be used in many small parts which require precision machining or intricate design work not possible with other materials. This versatility has allowed Beryllium Copper to become one of the most popular choice alloys due to its multiple uses applicable across industries.

Differences Between Tungsten and Beryllium Copper

The main differences between tungsten and beryllium copper are their properties and applications. Tungsten is a dense, heavy metal used in high-stress applications where weight is not an issue. On the other hand, Beryllium Copper is a relatively lightweight alloy used in applications where strength and durability are required, but weight is a concern. Tungsten is also more expensive than Beryllium Copper, which can impact its use in certain applications.

Properties of Tungsten

Tungsten is a refractory metal with the highest melting point and density of any metallic element. It is incredibly strong, durable, and resistant to wear and tear. Tungsten is also an excellent conductor of electricity and heat. Due to its high weight, tungsten is usually used in applications requiring density and strength. Some applications of tungsten include aerospace engineering, electrical contacts, and heating elements.

Properties of Beryllium Copper

Beryllium Copper is an alloy that consists of copper and beryllium. It is a non-ferrous metal with excellent strength, conductivity, and thermal properties. Beryllium Copper also exhibits excellent resistance to corrosion and wear and tear. Beryllium Copper is commonly used in the aerospace, oil, and gas industries due to its excellent mechanical properties. It is also used in electrical connectors, springs, and other high-performance applications.

Applications of Tungsten

Tungsten is used in various industries, including aerospace, military, and medical. One of the most common applications of tungsten is in lighting, where it is used in filament wires for incandescent lamps. Tungsten is also used in electrical contacts, furnaces, and welding electrodes. Due to its high density, tungsten is also used in vibration-dampening applications, such as golf clubs and tennis rackets.

Applications of Beryllium Copper

Beryllium Copper is used in various aerospace, defence, and electronics applications. Some of the most common applications of beryllium copper include electrical connectors, springs, and switches. It is also commonly used in oil and gas drilling equipment due to its excellent corrosion resistance and superior mechanical properties. Beryllium Copper is also used in the automotive and marine industries because of its strength and durability.


In conclusion, tungsten and beryllium copper are excellent materials with unique properties and applications. Tungsten is ideal for applications where high density, strength, and durability are required, while Beryllium Copper is better suited for applications where weight is a concern. Understanding the differences between these two materials can help you choose the best material for your project, whether you’re in the aerospace, automotive, or medical industry. Both tungsten and beryllium copper are valuable materials that can make a significant difference in your work.
