A look into the growing of Copper Wires

Copper has always been the fascinating metal for mankind. It has been a part of major advancements in the history of engineering, metallurgy and industrial upgrades. Copper has been used in minting coins, drawing elaborate chain-threads for stitching armours and making jewellery. With time, copper was amalgamated with different metals to form highly beneficial alloys. Nickel, iron, aluminium, tin and chromium are often alloyed with copper to make new materials that come with extensive anti-corrosive, anti-scratch and anti-tear properties. 


What makes copper so popular? 

Copper is abundantly found in the earth’s crust. It can be mined with other metals. The technique of separating the copper from its ores and compounds is fairly cost-effective. The impurities that often accompany the naturally mined copper can be separated out to obtain pure copper through different means. Electroplating and chemical separation remain the best methods to derive pure copper. The availability of pure copper ensures use in industrial, surgical and domestic appliances with amazing results. The use of copper wires for different engineering and cabling operations require specific properties that copper provides with unique proficiency. 

The following properties make copper ideal for use as wires in its bare, stranded and braided forms. 

 - Excellent Electrical Conductivity 
- Excellent thermal conduction in solutions and atmospheric medium 
- God resistance to corrosion 

- Malleability:  Copper can be hammered to form thin plates and sheets. This property is used to manufacture electrodes, solar plates and thermal blades in furnaces. 

- Ductility:  The property of copper to be drawn into thin wires makes it ideal choice for use in making electrical wires, and jewellery items. Ductility saves metal without compromising on the properties. The ductility property of bare copper wires has been the driving force behind the reducing size of electrical circuits and ease of laying them in high-rise buildings. Ductility of copper wires is also not affected with addition of other metals. Moreover, the insulation of copper wires together with ductility features ensures top-notch safety in the wiring and cable layouts. 

From bare wires to tin plated wires: List of advantages keeps growing 

Bare copper wires have been in use for over two hundred years now. It is often used with tin platting to blend in higher speciality. Gold plating and platinum plating is done in industries that require higher degree of conductivity. Even in jewellery wire wrapping, tin-platted bare copper wires are used to integrate cosmetic touch with anti-corrosive property. 


Bare copper wires have relatively long life time, but their performance and physical properties being to dwindle in wet and humid conditions. When plated with tin, the wholesale bare copper wires can last much longer. In industries that use 12 gauge copper wire with tin plating can have a life span ten times more than normal bare copper wires. The wire also remains free from issues of wear and tear. This property is essential in power transmission cables used over long distances. These wires often snap in torrid weather conditions. 

The maintenance and replacement of the tin plated copper wires is easy. With growing aerospace needs and underwater operations, copper wires are probable solutions to every innovative segment in the world today!

Stranded Copper Wires: Transforming the world of Metal Cables

Image
Choosing the right set of stranded copper wires for a project requires elaborate study. Not all layouts can be fitted with the stranded copper wires. Based on the wattage and current load, the proper diameter of the stranded set of copper wires is used. In domestic applications, the stranded types are usually not required. Only a wire with appropriate diameter can be placed in domestic and industrial layouts. Otherwise it causes serious fluctuations and short circuits. Most electricians fail to distinguish between the different types of metal wires used in the electrical systems. The wiring experts recommend the use of stranded copper wires where there is no limitation on the space or budget.   When it comes to use in contemporary appliances and power set-ups, the stranded copper wires have following advantages over the solid wires.    Residential purposes: The Stranded copper wire with shorter gauge diameter are used in the residential units. It saves the ov

Copper pipes: An insight about its diverse applications

Image
Copper falls in the genre of transition metals and it is used for numerous purposes. According to the historic data, it was used for the very first time during 8000 B.C. Since then, people began discovering diverse kinds of applications of this metal. During Stone Age, it was extensively used for making tools. After that, it began securing an important position in various industries. The color of this metal is reddish brown, but at times, it color turns to turquoise due to its salt. In the context of ductility, it scores really well and hence, it can be stretched and drawn into wires, without hassles. It possess high electrical and thermal conductivity and considering the same, it really doesn’t come as surprise when it is used in wide array of applications including machinery, roofing, utensils, electrical devices, plumbing, electrical wires, etc. Cooper pipes made up of copper prove to be suitable for diverse range of important applications. If you are keener to know about the dive

Why Tinned Copper Wire is better than Bare ones?

Image
Copper wires that are available in the market today are either bare wires, insulated with nickel or tin or bunched copper wires . The bare wires are rated under the regular bare 12 gauge copper wire. We take a close look at how bare copper wires are different from the tinned ones. Bare copper is a great choice in industries concerned with the manufacturing of electrical equipments and associated appliances and products. Car and domestic appliances are all driven by power connected by copper wires. Great conductivity doubled by extremely good anti-corrosion properties make copper wires made in bare form best option to be used in internal circuits as well as external relays used in transformers and over-head transmission lines. It has a fairly good tensile strength which means that it does not   get snapped in heavy rains or thunderous storms.   The durability is very promising and comes with good workable features. Bare copper wires are easy to draw and flatten and can be used
