Difference between Annealed Wire and GI Wire

Steel Wire is the most commonly used material nowadays. Every wire has its own significance for particular projects. Some wires are famous for their high tensile strength, while some are for their anti-corrosion properties. To know which type of wire is best for your project, you should know the difference between all types of steel wires. In this blog, we will discuss the major differences between Annealed Wire and GI Wire.

What is Annealed Wire?

Annealed Wire is a type of low-carbon steel wire made from MS Wire (Mild Steel Wire). MS Wire undergoes Annealing Process in which we heat the wire in a furnace at around 840 degrees Celsius for about 8-10 hours. After that, the wire is cooled down to room temperature. This annealing process enhances the physical properties of the wire.

What is GI Wire/Galvanized Wire?

GI Wire is manufactured by passing wire through a hot dip molten zinc solution. This process is known as the Galvanization process. The extra zinc layer acts as a barrier between the environment and the wire and hence protects it from rusting.

Manufacturing Process –

The manufacturing process of Annealed Wire and GI Wire is similar to the drawing process. After the drawing process, both wires are manufactured using different processes. To manufacture Annealed Wire, heat treatment is given to the wire to enhance its physical properties. In the Annealing Process, wire is heated in a furnace at about 840 degrees Celsius for 8-10 hours and then left to cool down at room temperature. Meanwhile, in the manufacture of GI Wire, the wire undergoes a hot dip galvanization process. In the hot dip galvanization process, the wire is immersed in a bath of molten zinc. Due to this process, the wire surface is coated with zinc.

Anti Corrosion Property –

If we compare the anti-corrosion properties of Annealed Wire and GI Wire, Annealed Wire is more prone to rusting. This is because of the extra layer of zinc present on the GI Wire surface. This zinc layer acts as a barrier between the environment and the wire and hence protects it from corrosion. In the case of Annealed Wire, the extra layer has to be applied at the end to protect it from rusting. There is no inbuilt property of corrosion resistance in Annealed Wire as that in GI Wire.

Pricing –

If we talk about the price of Annealed Wire and GI Wire, Annealed Wire is more affordable. This is because of its raw material i.e. MS Wire/Mild Steel Wire and easy manufacturing process. To manufacture Annealed Wire, there is no need for extra setup or extra chemicals. Whereas, in the case of GI Wire, an extra set of chemicals and processes is required which makes it more expensive.

Durability –

GI Wire is more durable as compared to Annealed Wire. This is because of the extra layer of zinc over its surface. This zinc layer protects it from rusting and hence increases the durability of the wire. Annealed Wire has no extra layer over it hence it comes in direct contact with the atmosphere. To make it durable, an anti-corrosion layer should be applied to it.

Flexibility –

Annealed Wire is more flexible than GI Wire. This is because of the heat treatment given to Annealed Wire. This heat treatment makes wire soft, easy to work, bent, or mold without breaking. Whereas GI Wire is stiffer and not very flexible.

In Conclusion, Annealed Wire and GI Wire both have their own benefits and drawbacks. Which one is best depends on the usability. If you are looking for the best quality wire under budget, then Annealed Wire is the best as it can become corrosion resistant by applying a layer over it.
