Description
Copper is a chemical element with the symbol Cu (from Latin:
cuprum) and atomic number *9. It is a ductile metal with very high
thermal and electrical conductivity. Pure copper is soft and
malleable; a freshly exposed surface has a reddish-orange color. It
is used as a conductor of heat and electricity, a building
material, and a constituent of various metal alloys. Most of the
copper we market is sourced from the Democratic Republic of Congo.
High purity scrap copper is melted in a furnace and then reduced
and cast into billets and ingots; lower purity scrap is refined by
electroplating.
Produced using Airslip technology, all our billets are homogenized
and **0 per cent ultrasound-inspected before delivery. Inherently
superior in quality and intrinsic purity, a large proportion of the
annual production is cast in high extrudability ***3 alloy. Our
extrusion billets are supplied for construction (windows and door
frames), transportation, engineering, consumer durables, automotive
forging, as well as many other applications. In ***3, our extrusion
billets were declared suitable for sustainable building practices,
as per the criteria defined by the US (LEED) rating system and the
Deutsche (DGNB).
Zinc, in commerce also spelter, is a metallic chemical element; it
has the symbol Zn and atomic number *0. It is the first element of
group *2 of the periodic table. Zinc is, in some respects,
chemically similar to magnesium, because its ion is of similar size
and its only common oxidation state is *2. Zinc is the *4th most
abundant element in the Earth's crust and has five stable isotopes.
The most common zinc ore is sphalerite (zinc blende), a zinc
sulfide mineral. Zinc production includes froth flotation of the
ore, roasting, and final extraction using electricity
(electrowinning). Click on the link below to order.
