In April 2001 manufacturers agreed to reduce lead content to 1.5%, or face a requirement to warn consumers about lead content. Keys plated with other metals are not affected by the settlement, and may continue to use brass alloys with a higher percentage of lead content. ... These may be "natural alloys" manufactured by smelting zinc rich ...
Agent Orange is a chemical herbicide and defoliant, one of the "tactical use" Rainbow Herbicides.It was used by the U.S. military as part of its herbicidal warfare program, Operation Ranch Hand, during the Vietnam War from 1961 to 1971. It is a mixture of equal parts of two herbicides, 2,4,5-T and 2,4-D.In addition to its damaging …
EPA is helping states to meet standards for common pollutants by issuing federal emissions standards for new motor vehicles and non-road engines, national emissions standards for categories of new industrial equipment (e.g., power plants, industrial boilers, cement manufacturing, secondary lead smelting), and technical and policy …
Engineering is the use of scientific principles to design and build machines, structures, and other items, including bridges, tunnels, roads, vehicles, and buildings. The discipline of engineering encompasses a broad range of more specialized fields of engineering, each with a more specific emphasis on particular areas of applied …
Sonar (sound navigation and ranging or sonic navigation and ranging) is a technique that uses sound propagation (usually underwater, as in submarine navigation) to navigate, measure distances (), communicate with or detect objects on or under the surface of the water, such as other vessels. "Sonar" can refer to one of two types of technology: …
The lead–acid battery is a type of rechargeable battery first invented in 1859 by French physicist Gaston Planté.It is the first type of rechargeable battery ever created. Compared to modern rechargeable batteries, lead–acid batteries have relatively low energy density.Despite this, their ability to supply high surge currents means that the cells have …
Any lead that is of 99.99% or greater purity can be classified as high purity lead.Extensive processes that lead to rigorous purification of the metal are used, and the diverse application of the material in a number of industries owing to its unique properties such as enhanced ductility, malleability and corrosion resistance is anticipated to boost …
The Black Country Living Museum (formerly the Black Country Museum) is an open-air museum of rebuilt historic buildings in Dudley, West Midlands, England. It is located in the centre of the Black Country, 10 miles west of Birmingham.The museum occupies 105,000 square metres (26 acres) of former industrial land partly reclaimed from a former …
Here are five ways manufacturers can minimise their carbon emissions. 1. Eco-design engineering. Manufacturers can lower their CO 2 emissions by considering and actively minimising the environmental impact of a product across its entire lifecycle, from material extraction and supply to end of life.

Steel is an alloy made up of iron with added carbon to improve its strength and fracture resistance compared to other forms of iron. Many other elements may be present or added. Stainless steels that are corrosion- and oxidation-resistant typically need an additional 11% chromium.Because of its high tensile strength and low cost, steel is used …
Copper is a chemical element with the symbol Cu (from Latin: cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity.A freshly exposed surface of pure copper has a pinkish-orange color.Copper is used as a conductor of heat and electricity, as a building material, and as …
Smelting Furnace of Iron Ore Laboratory-scale experiments showed that pig irons and steels of acceptable grade can be made by arc-furnace methods from east Texas siliceous ores containing less than 25 percent iron. Under highly reducing conditions, 97 to 99 percent of the iron in the ore was recovered as pig iron. Small quantities of limestone, …

Also, the amount of arsenic found in the hair of the famous frozen male, Ötzi the Iceman, suggests that he was involved in copper smelting; he died between 3300 and 3200 BC. Carbon dating tells us that humans were mining copper metal in Cheshire, UK, at least by 2280 BC. Humans began alloying copper around 4000 years after they began smelting it.
