Copper
Copper is a chemical element with the symbol Cu (from la, cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement. Copper is one of the few metals that can occur in nature in a directly usable metallic form ( native metals). This led to very early human use in several regions, from circa 8000 BC. Thousands of years later, it was the first metal to be smelted from sulfide ores, circa 5000 BC; the first metal to be cast into a shape in a mold, c. 4000 BC; and the first metal to be purposely alloyed with another metal, tin, to create ...

World Copper Agreement Of 1935
The World Copper Agreement, signed March 28, 1935, was an agreement by mining companies that attempted to create a worldwide copper cartel. The agreement formally created the International Copper Cartel. Uniting African, South American and European producers, the agreement aimed to "bring about better conditions in the production, distribution and marketing of copper throughout the world outside of the United States" through curtailment of production. To supervise the implementation of the agreement and amend breaches of it, the agreement provided for the creation of a Control Committee of 5 members.
