The best combination of characteristics of the copper-based alloys


The copper-beryllium alloys processed by NGK Berylco offer a wide combination of mechanical and electrical properties which is unique for copper alloys. The mechanical strength achieved after heat treatment ranks highest amongst all the copper alloy materials and is combined with a high electrical conductivity which outperforms that of bronzes. The Berylco alloys exhibit a wide range of optimum properties such as:




















High Strength & Elastic Modulus

Beryllium Copper alloys can achieve very high mechanical properties after heat treatment, up to 1500 Mpa in tensile strength and hardness as high as 450 Vickers.

The strength of these alloys allow for the design of smaller, lighter components that can endure high bending stresses when used as springs material.


Bending Formability

Beryllium Copper can be formed into complicated shapes in an annealed or cold-worked temper.

The highest mechanical properties can be achieved with proper heat-treatment after forming.

Among Mill-hardened material, ‘Type-B’ and ‘Type-S’ have especially well balanced performance in strength and formability.


High Fatigue Strength

Beryllium Copper exhibits excellent resistance to fatigue under reverse bending (up to 300 MPa) which qualifies its use in applications where other alloy fail to provide the same level of reliability.


High Electrical conductivity


Elevated Temperature Properties and Resistance to Stress Relaxation

Beryllium Copper can be used in a wide range of temperatures with little loss of mechanical properties, particularly at low cryogenic temperatures, but also at elevated temperatures which are above those normally acceptable for the standard copper alloys.


Corrosion Resistance


Wear and Abrasion Resistance

Beryllium Copper has excellent wear and abrasion resistance.


Non-magnetic and None-Sparking

Beryllium Copper are none-magnetic and none-sparking.



There is always a solution to your convenience…


Beryllium Copper alloys possess all of the characteristics listed above at the same time. Such a variety of properties altogether makes the Berylco alloys the essential and ideal material to realise numerous high-end and accurate parts used in all market places. All these properties at once for such a unique material often make the alloys of beryllium-copper the most economical alloys!


Beryllium Copper allows an engineer to employ a unique design approach when other materials will not perform.

Whatever the application or utilisation, you will always get the Berylco alloys required!
