Copper is too soft to be used alone in many materials, and people discovered long ago that it can be mixed with other metals to form strong alloys. Examples of this is copper&amp;#039;s mixture with tin to make bronze, or with zinc to form brass.&amp;lt;ref name=jeff/&amp;gt;&lt;br /&gt;

==Uses of Copper==&lt;br /&gt;
&lt;br /&gt;
The uses of copper by percentage (estimated) are shown in the Figure below.&amp;lt;Ref name=abt&amp;gt;Metals @ About.com. (July 31, 2015). &amp;#039;&amp;#039;Copper Applications&amp;#039;&amp;#039; [Online], Available: http://metals.about.com/od/properties/a/Copper-Applications.htm&amp;lt;/ref&amp;gt;&lt;br /&gt;

===Electrical===&lt;br /&gt;
[[File:Stranded_lamp_wire.jpg|200px|thumb|Figure 4. Copper wire.&amp;lt;ref&amp;gt;Wikimedia Commons [Online], Available: https://upload.wikimedia.org/wikipedia/commons/7/74/Stranded_lamp_wire.jpg&amp;lt;/ref&amp;gt;]]&lt;br /&gt;
&lt;br /&gt;
Copper is the major component of wiring. In a single vehicle there is about 1.5 [[kilometer]]s of copper wiring, with a total [[mass]] of about 20 [[kilogram]]s in small cars and 45 kilograms in luxury and [[hybrid car]]s.&amp;lt;Ref name=usgs&amp;gt;US Geological Survey. (July 31, 2015). &amp;#039;&amp;#039;Copper - A Metal for the Ages&amp;#039;&amp;#039; [Online], Available: http://pubs.usgs.gov/fs/2009/3031/FS2009-3031.pdf&amp;lt;/ref&amp;gt; Along with wiring of vehicles and other electronics, copper wiring is used in [[electrical generation]] and [[electrical transmission|transmission]] (aside from overhead [[Electrical transmission#Power Lines|power lines]], which are made from [[aluminum]]). &lt;br /&gt;
&lt;br /&gt;
Aside from its excellent conductivity, copper is also very [[ductile]] so it is very easy to work with. Specific examples of copper use in electrical applications include circuit boards, microchips, [[semiconductor]]s, [[magnet#Electromagnets|electromagnets]], [[electric motor]]s, [[wind turbine]]s, [[photovoltaic cell]]s, and much, much more. Basically any wiring aside from power lines are formed with copper.&amp;lt;ref name=abt/&amp;gt; &lt;br /&gt;
&lt;br /&gt;
===Construction===&lt;br /&gt;
&lt;br /&gt;
Copper is the standard material for plumbing not only due to its high [[melting point]] and corrosion resistance, but also because it does not allow for the growth of bacteria or viruses. It is also malleable and easy to solder; it is easy to bend and piece together. Examples of copper and its alloys in construction include [[heat exchanger]]s, [[pipeline]]s, agricultural water systems, handles, doorknobs and other building materials, and more.&amp;lt;ref name=abt/&amp;gt; &lt;br /&gt;
