Metalworking is the process of working with metals to create individual parts, assemblies, or large-scale structures. The term covers a wide range of work from large ships and bridges to precise engine parts and delicate jewelry. It therefore includes a correspondingly wide range of skills, processes, and tools.
Metalworking is a science, art, hobby, industry and trade. Its historical roots span cultures, civilizations, and millennia. Metalworking has evolved from the discovery of smelting various ores, producing malleable and ductile metal useful for tools and adornments. Modern metalworking processes, though diverse and specialized, can be categorized as forming, cutting, or joining processes. Today's machine shop includes a number of machine tools capable of creating a precise, useful workpiece.
The oldest archaeological evidence of copper mining and working was the discovery of a copper pendant in northern Iraq from 8,700 BCE. The earliest substantiated and dated evidence of metalworking in the Americas was the processing of copper in Wisconsin, near Lake Michigan. Copper was hammered until brittle then heated so it could be worked some more. This technology is dated to about 4000-5000 BCE. The oldest gold artifacts in the world come from the Bulgarian Varna Necropolis and date from 4450 BCE.
A metal (from Greek μέταλλον métallon, "mine, quarry, metal") is a material (an element, compound, or alloy) that is typically hard, opaque, shiny, and has good electrical and thermal conductivity. Metals are generally malleable — that is, they can be hammered or pressed permanently out of shape without breaking or cracking — as well as fusible (able to be fused or melted) and ductile (able to be drawn out into a thin wire). About 91 of the 118 elements in the periodic table are metals, the others are nonmetals or metalloids. Some elements appear in both metallic and non-metallic forms.
Astrophysicists use the term "metal" to collectively describe all elements other than hydrogen and helium. Thus, the metallicity of an object is the proportion of its matter made up of chemical elements other than hydrogen and helium.
Many elements and compounds that are not normally classified as metals become metallic under high pressures; these are formed as metallic allotropes of non-metals.

Qualtek's metal manufacturing services solve problems for medical, clean energy, aerospace and industrial applications. Qualtek uses state-of-the-art Rockwell hardness tester to quickly and accurately determine the hardness of heat-treated steel. For very small parts and for Carburized parts, Qualtek uses a special micro hardness tester. Samples for this device are encapsulated in resin, cross-sectioned and then the target small area is accurately measured for hardness. Located in beautiful Colorado Springs, CO, we are your All-under-one-roof resource for metal part stamping, finishing, and heat treating.
Welcome to the Investors Trading Academy talking glossary of financial terms and events. Our word of the day is “Industrial Metals”. Gold and silver may get all the glory, and look pretty, but when you want to build an economy, it's the industrial metals that steal the show. As such, base metals have emerged as a key way for investors to tap into the rapid development of emerging economies like China. As China builds new apartment buildings and factories, it needs iron for the trusses, copper for the pipes and aluminum for the appliances. The granddaddy of metals for most of the last millennium has been iron. Iron, by itself and as the major component in steel, is the most widely used metal in the world. Examples of industrial minerals include asphalt, silica, gypsum, and potash, along ...
