What are the types of metal fabrication, and what are their characteristics and differences?
Metal fabrication is the process of turning raw materials into finished products. It can be broken down into two main categories: primary and secondary metalworking. Primary metalworking involves the shaping, stamping, and welding of metal using manual or automated methods. It includes tasks like fabricating parts for machines and aircraft, as well as creating structural components like columns and beams. Secondary metalworking involves the processing of metals after they have been shaped or stamped. This can include things like machining, forming, and finishing. In this blog post, we will explore the different types of metal fabrication and their characteristics and differences. We will also highlight some of the most common uses for each type of metal fabrication in today’s economy.
Types of Metal Fabrication
There are many types of metal fabrication, each with its own unique characteristics and differences. Here are the most common types:
1. Casting: Cast metals are made by pouring liquid metal into a mold or pattern to create a finished product like investment casting, precision casting parts and steel investment casting parts. Some popular cast metals include aluminum, brass, and steel.
2. Shearing: Shearing is a process where thin sheets of metal are cut from a larger piece using a shear blade. Common shear blades include saws, lasers, and electric shears.
3. Rolling: Rolling is another process where thin sheets of metal are cut from a larger piece using rolling milling machines that rotate the piece at high speeds. The edges of the sheet can be smooth or have SERRA-WELLS (a series of ridges parallel to the direction of motion).
4. Milling: Milling is a process where layers of metal are separated by small cuts called chips. Mills can be horizontal or vertical and can be used to create round or rectangular pieces of metal.

Characteristics of Different Metals
There are a variety of metals that can be fabricated, with different characteristics and differences. Here are four types of metal fabrication, and their associated characteristics:
1. Sheetmetal fabrication: This is the most common type of metal fabrication, where sheets of metal are cut to size and then bent or formed into other objects. Sheetmetal is often used in car manufacturing, where it is stretched over the chassis to create the bodywork. It is also used in construction, where it forms the beams and girders that support buildings.
2. Wire fabrications: This type of fabrication uses wire as the material instead of sheets of metal. Wire is woven into patterns to create products like wires harnesses and cables. This type of fabrication is often used in aerospace engineering, as it allows for more complex designs than sheetmetal can achieve.
3. Machining: Machining involves using a machine to remove parts from a piece of metal using either rotary or cutting tools. This type of fabrication is often used in industrial applications, where it allows for large pieces of metal to be cut down to smaller sizes without having to use any other methods first. Machining also plays a major role in automotive manufacturing, as it forms the components that make up the engine block and other components.
4. Casting: Casting involves pouring molten metal into a mold designed specifically for that purpose. This process creates products like cars and missiles that are completely solid before they are finished

Differences in Metal Properties
Metal fabrication is the process of creating objects from metal. There are several types of metal fabrication, each with its own unique characteristics and advantages. Here are the four main types of metal fabrication:
1. Casting: This is the most basic type of metal fabrication, and it's used to create small objects like jewelry ornaments or parts for machinery. Castings are made from molten metal that's poured into a mold and then allowed to cool and solidify. The main advantage of casting is that it's relatively easy to change the shape of a cast object, which can be helpful when you need to create something that doesn't fit neatly into a preexisting mold.
2. Extruded: Extrusion is similar to casting in that it involves pouring molten metal into a mold and then allowing it to cool and solidify. However, instead of using a mold, extrusion uses pressure and heat to force the molten metal out of a nozzle or die. This process creates objects that are typically much thinner than cast objects, which makes them ideal for applications like electronic components or medical implants.
3. Forging: Forging is another type of metal fabrication that's used to create objects with complex shapes and intricate details. Like extrusion, forging involves forcing molten metal through a nozzle or die, but the difference is that forgers use hammering or other forms of percussion to help shape the metal before it solidifies. This process can be difficult because it requires
