When does copper melt?

When does copper melt? Copper is a semi-precious, reddish and metallic element. The name copper comes from "cyprum" in Latin which means "the metal from Cyprus". Cyprus has always been a country rich in copper. This metal is malleable, malleable and suitable for casting. It conducts heat very efficiently, making copper a useful metal in electronics.

High melting point

With a melting point of 1083 degrees Celsius, copper has been of great importance to Swedish industry and culture. Copper was for a long time an important export commodity. Internationally, the reddish metal has been used for several millennia, during the Bronze Age in bronze axes and razors and in the 17th century in bronze cannons and copper roofs. Today, copper is used in downpipes and gutters, as roofing material and for the distribution of heat and water. This is thanks to its good corrosion properties. There is also copper in cars and refrigerators, where the metal is used for pipes and radiators. Copper is used in electronic circuit boards, as electrical conductors and in electronic components for telecommunications. Copper has good solderability and conductivity.


The copper smelting process

A special furnace is used to melt copper, for example an electric induction furnace or a reverberation furnace. The furnace is heated to the desired temperature, which is higher than the melting point of copper. It is possible to smelt copper from many different sources, such as copper from mining or from recycled scrap. Recycled material is usually cleaned and processed before being smelted to remove impurities such as iron, sulfur and metals.

When the furnace is heated, the copper material can be placed. This happens in larger batches or continuously, based on how the industrial process works. The furnace provides a controlled environment where the copper can be melted using electrodes, induction coils or burners. As the intense heat is raised in the furnace, the copper material gradually melts, creating a flowing liquid. In some cases, flux may be added to remove impurities. Based on what the copper is to be used for, it can then be cast into different shapes or subjected to other production processes.
