The use of copper can be traced back to at least 9000 BC in the Middle East, making it one of the oldest metals used by humans. At first, copper was used primarily for decorative purposes, such as jewelry and statues. However, as people began to discover its useful properties, such as its ability to conduct electricity and heat, copper became a highly valued material for tools and weapons. The first known smelting of copper occurred in Serbia around 5000 BC and was quickly adopted by other cultures in the region. From there, copper working spread throughout the ancient world, including Egypt, Greece, and Crete. The Egyptians, in particular, were skilled at using copper to create intricate jewelry and other decorative objects. During the Bronze Age (around 3000 - 1200 BC), copper was often alloyed with other metals, such as tin, to create stronger materials for tools, weapons, and even armor. The resulting material, known as bronze, was widely used throughout the ancient world and played a critical role in the development of early civilizations. In addition to its practical applications, copper also had cultural and spiritual significance for many ancient cultures. The ancient Mesopotamians, for example, believed that the god of wisdom, Ea, presented copper to humankind as a gift. The Greeks associated copper with the goddess Aphrodite and often used it to create images of her. Today, copper remains an important metal in a wide range of industries, including electronics, construction, and transportation. It is also valued for its antimicrobial properties and is used in many healthcare settings to help prevent the spread of infection. Despite its long history, copper continues to be an essential material in our modern world [url=http://nopm.cc/]copper recycling facilities[/url] copper disposal site

Exploring 70 Centuries of Mining History


There are several reasons why copper wire is not used as a fuse wire. First and foremost, copper is a good conductor of electricity and has a low resistance. This means that it will allow high current to flow through it without breaking, which defeats the purpose of using a fuse as a safety device. A fuse wire is designed to break when the current through it exceeds a certain level, which protects the circuit from damage and prevents the risk of fire or injury. Secondly, copper has a high melting point of around 1,083В°C. This means that it would require a very high current and a long period of time for the copper wire to reach its melting point and break. In comparison, most standard fuse wires are made from materials with lower melting points, such as tin, lead, or zinc. These materials are specifically chosen for their ability to break quickly and safely when the current exceeds a certain level. Furthermore, copper is a relatively expensive material compared to other options, making it less practical and cost-effective to use as a fuse wire. Other materials, such as aluminum and silver, are also better conductors of electricity than copper, making them more suitable for use in electrical applications. In summary, copper is not a suitable material for use as a fuse wire due to its low resistance, high melting point, and cost. Materials with lower melting points and better conductive properties, such as tin or zinc, are preferred for use in fuse wires to ensure the safety and protection of electrical systems
