What is metallurgy?
The extraction of metals from their ores and then refining them for use is known as metallurgy. This is applied to the production of metals, and the engineering of metal components for usage in products for consumers and manufacturers.
The metallurgical industry supplies essential materials for the production of various products that are intended to improve the quality of our lives. It covers a wide range of disciplines including, metal recycling, foundries, the manufacture of raw products and the manufacture of products and intermediates for various industries such as the automotive, aeronautical and packaging industries.
The industrial revolution placed metals as a main ingredient of technology and has become the very foundation of our modern society and its growth. One cannot envision a life in which electronics, transportation systems, buildings, and machines are not part of our daily lives.
The chemical industry is growing in Zambia and comprises of companies that produce industrial chemicals and convert raw materials into different products. The products from the industry, such as detergents, soaps and perfumes, are purchased directly by the consumer, others are used as intermediates to make other products.
Metallurgy is the technology of metals and the way in which science is applied to producing metal components.
Common engineering metals include aluminium, chromium, copper, iron, magnesium, nickel, titanium, zinc, and silicon. These metals are most often used as alloys with the noted exception of silicon. Much effort has been placed into understanding the iron-carbon alloy system, which includes steel and cast irons.
The three main branches of metallurgical engineering are physical metallurgy, extractive metallurgy and mineral processing.
Chemicals - A chemical is any substance that has a defined composition. In other words, a chemical is always made up of the same "stuff." Some chemicals occur in nature, such as water. Other chemicals are manufactured, such as chlorine (used for bleaching fabrics or in swimming pools).
Examples of chemicals include the chemical elements, such as zinc, helium, and oxygen; compounds made from elements including water, carbon dioxide, and salt; and more complex materials like your computer, air, rain, a chicken, a car, etc.
Rubber is an elastic substance obtained from the exudations of certain tropical plants, natural rubber or derived from petroleum and natural gas, synthetic rubber. Because of its elasticity, resilience, and toughness, rubber is the basic constituent of the tires used in automotive vehicles, aircraft, and bicycles.
Rubber is an incredibly versatile, all-purpose material that is used across a huge range of domestic and industrial applications. From the natural rubber derived from rubber trees through to an extensive array of synthetic rubbers, there really is a rubber material for every occasion.
Plastics are a wide range of synthetic or semi-synthetic materials that use polymers as the main ingredient. Their plasticity makes it possible for plastics to be moulded, extruded or pressed into solid objects of various shapes.
Types of Plastic
Collectively, Polyethylene is the most common plastic in the world, but it's classified into three types: High-Density, Low-Density and Linear Low-Density. High-Density Polyethylene is strong and resistant to moisture and chemicals, which makes it ideal for cartons, containers, pipes and other building material
