(2) Non-ferrous Metals Non-ferrous metals refer to metals and alloys other than iron and carbon. They are mainly divided into: Light Metals: Main metals: Aluminum (Al), Magnesium (Mg), Titanium (Ti) Main alloys: Aluminum alloy, Magnesium alloy, Titanium alloy Uses: Aerospace, transportation...

Materials are classified under the three categories of (i) metals (ii) non-metals and composites. Of these, metals and its alloys broadly meet all requirements to be considered as the most suitable...doi:10.1007/978-981-10-4684-1_2Lahiri, Amiya Kumar...
Metals: Metallic materials are normally combinations of metallic elements. They have large numbers of nonlocalized electrons;that is,these electrons are not bound to particular atoms. Many properties of metals are directly attributable to these electrons. Metals are extremely good conductors of electricit...
Nonmetals sulfurS diamondC graphiteC Metals oreA sample of gold ore. Gold,silver, andcopperare members of the samegroup (column) in theperiodic table of elementsand therefore have similar chemical properties. In the uncombined state, their atoms are joined by the fairly weakmetallic bond. These...
The air flow velocity found was to be one of the crucial parameters for enrichment of metals. The superficial air flow velocity is optimized for efficient separation of metals and nonmetals of PCBs. 展开 关键词: air classification crushing printed circuit boards recycling waste treatment ...
grouping the then known elements as metals and non-metals. Later further classifications were tried out as our knowledge of elements and their properties increased. 5.1.1 Döbereiner’s Triads In the year 1817, Johann Wolfgang Döbereiner, a German ...
