Lead in wire is one of the heavy wires which are used to connect a switch with the cap. These wires comprise a steel core which is surrounded by nickeliron alloy. The amount of nickel is more than the iron in such wires and this is the reason that products made of this is expensive than other.

Lead in wires are used almost in all electrical devices with glass envelops. These wires are used to conduct electrical current and also help other lamp parts. These wires have been produced from many years ago. The main purpose of these wires is to produce electric current in lamp. These wires are generally consisting of three parts that is innerlead, seal wire and outerlead. The innerlead is the part between the glass seal and tungsten and the outerlead is the part between the glass seal and lamp foot. The inner leadwire is made of nickel because of its high melting point. Nickel is an expensive material and so lead in wires are also expensive. The intermediate wire is positioned in stem of glass. This intermediate wire is a dumet wire. Dumet wire is a nickeliron core which is coated with copper layer. These are made up of different material and dimensions and also available in wide varieties.

It is not so easy to produce these wires as it requires accurate measurement. To produce these wires, straightening, and cutting should be accurate. The welding of the wire parts must be done carefully to avoid any mistake. Even a fraction of millimeter can make difference. That mean if the cutting or straightening is not done accurately then the lead in wire may be dangerous. The whole process is done in three steps. In first step the wires are straightened and after when properly straight, these are cut accordingly. And in final step these cut pieces of wire are welded together to make original lead in wire.

The produce wire is strong and reliable. Another important thing that should be kept in mind is its packaging. The packaging must be proper so that it becomes safe. Along with this it should be keep in safe place. The reason is otherwise during transportation of electrical material from one place to other there may be chance that these are destroyed. These wires are used to connect glass and metal to produce electricity. These wires may be used in gas welding processes. In these days, lead in wires are used widely as these are better, trustworthy. There are various companies available that produces products made of lead in wire.

These lead in wires are used in manufacturing of light bulbs. Light bulbs which are made of different material used metal such as nickel and tungsten to make lead in wires. The purpose is to connect the filaments to the electrical component in order to produce electricity. It is also used in lamps and electronic tubes. These are used in manufacturing of compact fluorescent bulbs, high intensity discharge bulbs, miniature, automotive, recreational and vehicle bulbs and many more.
