Copper
(Cu), the chemical element, is an
off red material that is softer relative to the other metal type
materials that we are familiar with (i.e. steel, stainless
steel, iron, etc.). The main copper attribute, as it
pertains to the general consumer, is the fact that it essentially
does not rust. The fact that it is easy to work with
(soft, ductile, low relative melting point, etc.) comes in a
close second. Its household and industrial performance,
weighted with a price variable, as compared to other metals also
puts it high on the list.
Copper is non magnetic due to the fact that it
contains no magnetic elements such as lead. |

Atomic Number is an
experimentally determined number characteristic of a chemical
element that represents the number of protons in the nucleus
which in a neutral atom equals the number of electrons outside
the nucleus and that determines the place of the element in the
periodic table.
Atomic Radius is a measure of the size of an atom, assuming the atom has the shape
of a sphere.
Atomic Symbol is one,
two, or three letters used to
represent the atom in chemical formulae.
Atomic Weight is the total mass of just one atom
of an element.
Boiling Point is the exact temperature at which a material, such as copper, boils.
Crystal Structure is the order in which atoms are arranged in a material. These
arrangements have a direct effect on the physical properties of
the material. These arrangements commonly take the form of
cubes, rectangular solids, hexagonal solids, etc.
Density is the quantity per unit volume, unit area, or unit length.
Electrical Resistivity is the
electrical resistance of the body of
unit length and the unit cross-sectional area or weight. The value of 1/58 ohm-mm2 divided by metre at 20 C is the resistivity equivalent to
the International Annealed Copper Standard (IACS) for 100
percent conductivity. This means that a wire of 100 percent
conductivity, 1 metre in length and 1 square millimeter in
cross-sectional area would have a resistance of 0.017241 ohms at
20 C.
Melting Point is the
temperature at which a solid substance begins to undergoe fusion, changing from a solid to a liquid
state.
Thermal Conductivity is the ability of a
material to conduct heat. |
