Manufacturing process:

Pure aluminum does not occur naturally. It is divided into three stages: in the first, bauxites, which contain aluminum, are extracted from the ground. Secondly, bauxites are processed to obtain alumina or aluminum oxide and finally, in the third stage, pure aluminum is produced by electrolytic reduction, a process in which aluminum oxide is decomposed by electrical current. There is a lot of variation in bauxites. Structurally they can be solid and dense or brittle. The next stage in the production chain is the processing of bauxite into alumina, a white powder principle of the Bayer process is as follows: the crystallized aluminum hydrate found in bauxite dissolves easily in concentrated caustic turf. To create the right environment, another component is needed for electrolysis, and that component is cryolite. It is a rare natural mineral that, due to its scarcity in nature, has been manufactured artificially. Everything is ready for the last stage: electrolytic reduction to manufacture aluminum. The reduction area is the main area of an aluminum foundry

Ecological: Renewable and non biodegradable.

Alternative materials:

Aluminum: It would be lighter, cheaper and can conduct electricity almost as effectively as copper. However, aluminum wires may require larger diameters, after all I think it is better using copper.

Origin: Metallic.

Manufacturing process:

It begins with the extraction of copper raw materials from mines. Once mined, the raw copper is processed and purified through smelting and electrolytic refining to produce high-purity copper cathodes. The next step is wire drawing, which involves reducing the diameter of the copper rods. They are then fed into a drawing machine, which pulls the copper through a series of consecutive dies. The result is a long, thin, uniform copper wire. After the drawing process, the copper wire is annealed. This is a heat treatment and an insulating coating can be applied to provide electrical insulation and protection against environmental factors. Throughout the manufacturing process, strict quality control measures are implemented to ensure that the final copper wire product meets industry standards and customer requirements.

Functions: Isolate the copper from the outside.

Properties:

Visual: Opaque.

Thermal: Low melting point and thermal insulator.

Electrical: Electrical insulator.

Mechanical: Stainless, lightweight and impermeable.

Ecological: Renewable and biodegradable.

Alternative materials:

Synthetic rubber: it would perform the same function perfectly but it would not be neither biodegradable or renewable which would have a bad impact on the planet

Origin: Natural.

Manufacturing process:

Natural rubber begins as latex, the manufacturing process begins with collecting the latex from rubber trees and begins with markings or cuts in the bark of the tree. The most common process is coagulation, a process that curdles or thickens polyisoprene into a mass. The coagulation process lasts approximately 12 hours. Different types of synthetic rubber A process called addition polymerization joins molecules into long chains. Another process, called condensation polymerization, removes a portion of the molecule as the molecules join together. Examples of addition polymers include synthetic rubbers made from polychloroprene (neoprene rubber), an oil- and gasoline-resistant rubber, and styrene butadiene rubber (SBR), used for non-rebound rubber in tires.

Ecological: Renewable and non biodegradable.

Alternative materials:

Cardboard: It can perform almost the same as plastic and is already used by some companies, and it has a better impact to the planet because it can be recycled easily.

Origin: Synthetic.

Manufacturing process:

The main raw materials used in the production of plastics are hydrocarbons, which come from coal, natural gas and oil. Polymerization is the method used to create plastic polymers. Polyethylene and polypropylene are produced by addition polymerization, although nylon and polyester are formed by condensation polymerization. Addition polymerization can improve the color, strength, flexibility, heat and UV resistance, and other properties of the plastic. The plastic takes its final shape during the molding process. Various molding processes are used in the production of plastics, including rotational molding, blow molding, extrusion, and injection molding. The choice of molding technique is influenced by the type of plastic, the complexity of the component and the production volume. For example, extrusion is best used to create long, continuous shapes.
