Beryllium Copper and Its Characteristics Overview

Beryllium copper, also known as beryllium bronze, is a copper alloy with beryllium as the main alloying element. It possesses a series of excellent physical and chemical properties such as high strength, high elasticity, high hardness, fatigue resistance, and corrosion resistance. These characteristics make beryllium copper widely applicable in various fields.

Here are some common alloy material numbers of beryllium copper:

C17200 Beryllium Copper

This alloy is also known as Beryllium Copper 25, which is composed of copper and 1.8-2.0% of beryllium. It possesses excellent corrosion resistance and high strength, and thus can be widely applied in fields such as aerospace and manufacturing.

C17000 Beryllium Copper

This alloy is also known as Beryllium Copper 174. It is mainly composed of copper and approximately 1.7% of beryllium, along with a small amount of nickel and silicon. It has excellent electrical conductivity and corrosion resistance, and thus can be used in electronic devices and battery applications for electrical appliances.

C17510 Beryllium Copper

This copper alloy is also known as Beryllium Copper 3. It is composed of copper, 1.8-2.0% of beryllium, and a small amount of nickel and silicon. It has excellent wear resistance and durability, and is commonly used for manufacturing molds and templates, etc.

C17500 Beryllium Copper

This alloy is also known as Beryllium Copper 10. It is composed of copper, 1.9-2.2% of beryllium, and a small amount of nickel. It has excellent thermal conductivity, mechanical properties, and corrosion resistance, and is typically used to manufacture heat exchangers, construction machinery, and seawater disinfection equipment, among others.

Additionally, some common copper alloys also contain a small amount of beryllium. These alloys are usually denoted by the code "BeCu" for their material designation. For instance, hard brass (Phosphor Bronze) and aluminum bronze (Aluminum Bronze), which are commonly used in the manufacturing of electronic devices, all contain a small amount of beryllium.
