Alloy 42 – The Benefits of Alloy 42 for Electronics

Looking to buy Alloy 42 from a trusted stockist? Speak to City Special Metals about your requirements today.

Electronic devices have become a staple in both personal lifestyles and business industries. With such a huge market demand that is constantly growing, there are a number of factors manufacturers need to consider when it comes to manufacturing these electronics.

Material Characteristics for Electronics

The components that go into these communication, electronic devices need to be built using the right materials in order for them to work correctly and efficiently. Some of the considerations that need to be made include:

Flexibility and Workability

The material needs to be versatile in order to be manipulated into the precise dimensions.


Electronic devices commonly generate a large amount of heat when in operation, so the material needs to be heat-resistant.


Due to being used in a variety of different environments and industries, electronics need to be able to withstand any risk of corrosion that may occur in the atmosphere.

Electrical Conductivity

It goes without saying that the material needs to be able to conduct electricity.

Alloy 42 in Electronics

Alloy 42 is an iron-nickel alloy, consisting of 42% nickel. It is commonly used in many electronic components such as semiconductor packages, tubes, CRT electron guns, and automotive and industrial lamps. As a controlled expansion alloy, it has low thermal expansion characteristics over a range of temperatures which is desirable.

Alloy 42 has good workability, weldability, and is shock-resistant. It is perfect for glass-sealing applications in microelectronic components and vacuum devices, on top of lead-in-wires required for electric light bulbs. As you can see, it holds all of the characteristics needed for electronic manufacture.

Other Alloys Suited for Electronics

Commercially pure or low-alloy nickel has characteristics that are beneficial to the electronic industry. With high electrical and thermal conductivity, and good ductility and malleability, it is ideally suited to the manufacture of electrical components.

Copper OFHC also showcases characteristics that are required for electronic devices. Our copper elements are each thermally and electrically conductive, with excellent corrosion resistance and workability. It is commonly used in electronic equipment such as conductors, microwave mechanisms and transistor elements.
