WHAT IS METAL?
A metal is a chemical element that is a good conductor of both electricity and heat. Metals are malleable and ductile and have lustrous appearance. They have moderate to high physical constants and high tensile strength. Metals are further divided into two main groups - ferrous and non ferrous metals.
TYPES OF METAL
• FERROUS METAL
These are metals which contain iron. They may have small amounts of other metals or other elements added, to give the required properties. All ferrous metals are magnetic and give little resistance to corrosion.
Example: Wild steel, Carbon steel, Cast iron, Wrought iron, Stainless steel

It therefore includes a correspondingly wide range of skills, processes, and tools. These are several process of working with metal:
CASTING
Casting is a manufacturing process by which a liquid material is usually poured into a mold, which contains a hollow cavity of the desired shape, and then allowed to solidify. The solidified part is also known as a casting, which is ejected or broken out of the mold to complete the process. Casting is most often used for making complex shapes that would be otherwise difficult or uneconomical to make by other methods. Example is sand casting.

|Investment casting is sometimes called lost wax process where a ceramic mold is used to form the desired part. To fabricate the ceramic |
|mold, a metal mold is made by machining or casting. Wax is then injected into the mold and is removed after it cools. The wax, which |
|resembles the desired part, is then coated with ceramic slurry in several layers. The completed ceramic slurry is placed in a furnace to |
|harden and the wax removed by melting and evaporation. The desired part is made by filling the mold cavity with molten metal. After |
|solidification, the mold is destroyed and the part removed. Investment casting is capable of surface finishes such that machining is not |

It has a dynamic distillation unit which uses the internal scra[er blade and it can be a fixer boiler. It is used when the solvents are being distilled it contains encrusting materials that build up on the inside walls pf the distillation boiler. It reduces the heat transfer and it lopwers the output of the distillation system.
New technologies were used such as alloying and casting metals for tools, weapons, and luxury goods.
As for metal, it has many uses. In fact, modern civilization has thrived off of things where iron is used like: buildings, car frames, bridges, and much more.
3D printing or additive manufacturing is a process of making three-dimensional solid objects from a digital design. The creation of a 3D printed object is achieved using additive processes. In an additive process the desired object is created by laying down successive layers of material (usually molten alloy or plastics) until the entire object is formed. Each of these layers can be seen as a thinly sliced horizontal cross-section of the eventual object.

Materials Technology Corporation was founded in 1984 by a venture capital-backed group of MIT scientists for the purpose of making advancements in ceramics processing technology. At inception, MTC had no actual products and process technology, but quickly made several innovations in the field of ceramics technology, for example: tape casting (flat, smooth sheets of ceramics for use in microelectronics), "Quickset" molding technology (a revolutionary development in 3-dimensional molding), and multi-layered ceramics molding.
MetalWorks is a company that produces and distributes steel file cabinets and lockable steel storage boxes, known in the Industry
P2 which is full annealing of the material after the operation P1, an operation P3 which is mechanical processing the material after operation P2, and an operation P4 which is soft annealing the material after operation P3.
The metal surfaces are first ground and packed which locks the metal together. Metal spacers and cladders are used to maintain a curtain space between the metals. Then a frame is used to hold the explosion powder.
Most of the metals in Periodic Table have high malleability. This also includes iron, aluminium and copper. By the term ‘malleable’, people mean, that the material can be easily shaped, reformed, stretched or other most physical changes, without breaking itself. Aluminium would be the highest malleable metal out of these three, as people created aluminium foils, which do not break under normal circumstances (only if someone would rip it). The second most malleable metal would be copper, because people created wires, which are larger in width than aluminium foil. Last, out of these 3 is the iron. With iron people can create small pieces that would not break, but they would still be larger compared to the metals above.
Steel fabrication is the process of creating structures by bending, cutting, shaping, and otherwise assembling pieces of steel. If you have ever noticed the steel frame of a building as it is being constructed, you have witnessed the product of steel fabrication. Steel fabrication experts are experienced and knowledgeable in the steel fabrication process, as well as what may occur if there are errors in the steel fabrication process. Steel fabrication experts are valuable in a variety of cases, such as premises liability cases, workers compensation claims, and, of course, construction litigation.
Product development: Using the plastic moulding skills, it can develop new or improved products that will appeal to the customers (for example, improved skylights to reduce heat loss).
18. Metallurgy - Metallurgy is the science or technique of heating, and/ or working metals to give them a desired shape or desired properties. The word originated in ancient greece
BMW Group uses various different materials for the production of these components. Accordingly, the casting methods used are diverse and innovative. In engine production the cast components is processed using high precision, computer controlled machine tools, the workers being predominantly
Steel products were defined by several attributes which determined the product application and defined quality. Grade described the metallic (chemical) composition of the steel, or the elements added to the basic recipe of iron and carbon to create the desired properties. Product described the shape of the product, including semi-finished shapes (blooms, billets and bars) and finished shapes (wires and coils). Surface finish described the smoothness and polish that could be applied to the material’s surface to enhance presentation. Size described the latitudinal and longitudinal dimensions of the product. Structural quality described the absence of breaks in the inner metallic structure. Surface quality described the absence of cracks or seams on the surface. Because specific applications called for specific attributes, many products were customized along one or more attributes for the customer. However, of all attributes, customers valued most the grade, which determined product performance.
