  • Metals are often extracted from the Earth by means of mining, resulting in ores that are relatively rich sources of the requisite elements. Ore is located by prospecting techniques, followed by the exploration and examination of deposits.

  • Metals are good conductors, making them valuable in electrical appliances and for carrying an electric current over a distance with little energy lost.


  • Metal production, as an indispensable industrial branch of the modern society, has responded to environmental challenge by high re-cycling rate of metal, improved energy efficiency, and other solutions based on clean technology.

  • Canon has developed a fast metal-mold production system that consolidates the metal-mold production process into a consistent 3-D system incorporating mold design and computer-aided manufacturing (CAM) programs, machining, assembly, and measurement.

  • Commercial HIsmelt plants will provide an alternative ironmaking route that offers competitive solutions to meet the metallics requirement of the iron and steel industry.
  • Superplasticity in metals is defined by very high tensile elongations, ranging from two hundred to several thousand percent.


  • As the world's third most widely used metal, copper is an important element in global industrial development and is considered a barometer of economic expansion.
