Laptops are made from assorted plastics, composites, semiconductors and metals. It all depends on the component. The outer casing is commonly made from ABS plastic or Magnesium alloys. Motherboard is made of high temperature glass reinforced epoxy resin.
GPUs are silicon layered with tantalum and palladium transistors and capacitors for better storage on a smaller chip, which is perhaps the most interesting of the materials used for a GPU and RAM cards are made from a mind-boggling array of chemicals and copper, boron, cobalt, tungsten, for starters.
Minerals & Electronics. There are many minerals found in electronics we use every day, but the three minerals were going to talk about are Cassiterite, Coltan, and Gold. All these minerals are mined and extracted from the Eastern Congo and many other places around the world.
- Pure silicon crystal of maximum about 300 square mm - This is like 99.9999999 % pure silicon and is probably costlier than gold, weight for weight.
- Doping materials - These are diffused onto the silicon to form wires, transistors, resistors and capacitors - various rare earth elements, in minute quantities.
Metals. Many laptop bodies are made of the element aluminium, used for its light weight, strength and appearance. Steel is also a common material for structural support components and hardware like screws; steel is mostly iron, but also contains the elements carbon and nickel.
Though there is a wide variation among materials used to manufacture these types of computers, there are many common elements including copper, gold, aluminum, zinc, iron and nickel.
Generally there are three metals in CPU Chips and they are: Silver, Gold, and Copper. Most of the time the primary metals are only gold and copper, but you can find silver in there.
Component. Computers are made up of many different parts, such as a motherboard, CPU, RAM, and hard drive. Each of these parts are made up of smaller parts, called components. For example, a motherboard includes electrical connectors, a printed circuit board (PCB), capacitors, resistors, and transformers.

Core Technologies are the building blocks of technology systems. The major Core Technologies are: Mechanical Structural Materials Electrical Electronic Thermal Fluid Optical Biotechnology. 3 We use these technologies to help us solve problems and extend human capabilities.
Another advantage of new technology is that it allows companies to automate functions that previously required employees. Tasks like data entry and analytics, bookkeeping, and contact management can be partially or completely automated, which allows businesses to work more efficiently without the risk of human error.
Transportation technology refers to tools and machines used to solve problems or improve conditions in respect to the movement of people and goods.
Technology can improve the accuracy of planning in management by providing your managers with the data they need to make effective decisions. Technology solutions gather data from internal and external sources, store them in a data warehouse and provide managers with access via a network.
Information is one integral component that helps determine the course of all businesses. Information can be used to analyze past performance, expenditures, revenues and more, but it can also be used to predict a pattern for the future. This is why technology management is so vital to the heartbeat of business today.
Materials technology is a relatively comprehensive discipline that begins with the production of goods from raw materials to processing of materials into the shapes and forms needed for specific applications. About 50 engineers graduate annually from the Department of Materials Science and Engineering.
Characteristics of technology. Technology is defined as “purposeful intervention by design”, and technological practice as the activity through which technological outcomes are created and have impact in the world. Technological outcomes are designed to enhance the capabilities of people and expand human possibilities.
Materials are generally split into four main groups: metals, polymers, ceramics, and composites. Let's discuss each of them in turn. Metals are materials like iron, steel, nickel, and copper.
Materials are the matter or substance that objects are made from.
We use a wide range of different materials daily; these might include:
- metal.
- plastic.
- wood.
- glass.
- ceramics.
- synthetic fibres.
- composites (made from two or more materials combined together)
A material is a substance or mixture of substances that constitutes an object. Materials can be pure or impure, living or non-living matter. New materials can be produced from raw materials by synthesis. In industry, materials are inputs to manufacturing processes to produce products or more complex materials.
A description of some common physical and mechanical properties will provide information that product designers could consider in selecting materials for a given application.
- Conductivity.
- Corrosion Resistance.
- Density.
- Ductility / Malleability.
- Elasticity / Stiffness.
- Fracture Toughness.
- Hardness.
- Plasticity.
From stone and bronze to steel and concrete, materials are useful for a particular purpose because they behave in a certain way under certain conditions: they have particular qualities, which we call their properties. Understanding these properties is what materials science is all about.

Everyday Materials
- Distinguish between an object and the material from which it is made.
- Identify and name a variety of everyday materials, including wood, plastic, glass, metal, water, and rock.
- Describe the simple physical properties of a variety of everyday materials.
The most electrically conductive element is silver, followed by copper and gold. Silver also has the highest thermal conductivity of any element and the highest light reflectance.
There are now about 300,000 different known materials (if you named one every second, it would take you more than three whole days and nights just to get through the list!). And as materials scientists create and combine materials in new ways, the number's almost infinite.
20 Types of Materials
- Plastic. A broad category of organic compounds that are molded into a wide variety of parts, components, products and packaging.
- Metals. Metals and alloys such as iron, aluminum, titanium, copper, tin, nickel, silver, gold, steel, brass and bronze.
- Wood.
- Paper.
- Natural Textiles.
- Synthetic Textiles.
- Leather.
- Fibers.
Materials can generally be further divided into two classes: crystalline and non-crystalline. The traditional examples of materials are metals, semiconductors, ceramics and polymers. New and advanced materials that are being developed include nanomaterials, biomaterials, and energy materials to name a few.
Materials can be classified into four main groups: metals, polymers, ceramics, and composites. Metals are materials on the left side of the periodic table of chemistry and include ferrous metals that have iron inside them (including steel) and nonferrous metals that don't.

Hardness is a measure of how easily a material can be scratched or indented. Hard materials are often also very brittle - this means they have a low resistance to impact . Well known hard materials include diamond and hardened high carbon steels. Same units as for tensile strength.
Types include:
- Biotic materials. Wood (rattan, bamboo, bark, etc.) Natural fiber (silk, wool, cotton, flax, hemp, jute, kapok, kenaf, moss, etc.)
- Inorganic material. Stone (flint, granite, obsidian, sandstone, sand, gems, glass, etc.) Native metal (copper, iron, gold, silver, etc.)
- Other natural materials. Soil.
Materials science is an interdisciplinary field involving the properties of matter and its applications to various areas of science and engineering. It includes elements of applied physics and chemistry, as well as chemical, mechanical, civil and electrical engineering.
