Copper is a metal element, is also a transition element, chemical
symbol Cu, English copper, atomic number 29. Pure copper is a soft
metal with a red-orange metallic luster when cut and a purplish red
color in its elemental form. Ductility, high thermal and electrical
conductivity, so the cable and electrical, electronic components
are the most commonly used materials, can also be used as building
materials, can be composed of many kinds of alloys. Copper alloys
have excellent mechanical properties and low electrical
resistivity, of which the most important are bronze and brass.
Copper is also a durable metal that can be recycled many times
without damaging its mechanical properties.
Divalent copper salts, the most common copper compound, are often
blue in their hydration ions and green in their chlorine ligands.
They are the source of colour for minerals such as azurite and
turquoise, and have historically been widely used as pigments. The
corrosion of copper building structures produces verdigris (basic
copper carbonate). Decorative art mainly uses copper and
copper-containing pigments.
Copper was one of the earliest metals used by man. As early as
prehistoric times, people began to mine open-pit copper and use it
to make weapons, tools and other utensils. The use of copper had a
profound impact on the progress of early human civilization. Copper
is a metal found in the earth's crust and oceans. The copper
content in the earth's crust is about 0.01%, and in individual
copper deposits, the copper content can reach 3% ~ 5%. Most of the
copper in nature is found in compounds called copper ores.
The activity of copper is weak, and the reaction of iron and copper
sulfate can replace copper. Copper is insoluble in nonoxidizing
acids.
Advantages:
1, high conductivity
2. Good thermal conductivity
3, good weldability
