T2 COPPER COIL

A chemical element, its chemical symbol is Cu (Latin: Cuprum), its atomic number is 29, and it is a transition metal. Copper is a purple-red shiny metal with a density of 8.92 g/cm3. Melting point 1083.4±0.2℃, boiling point 2567℃. Common valence +1 and +2.

Ionization energy 7.726 electron volts. Copper is one of the earliest metals discovered by humans and one of the best pure metals. It is slightly hard, extremely tough and wear-resistant. It also has good ductility.

It has good thermal and electrical conductivity.

Copper and some of its alloys have good corrosion resistance and are very stable in dry air. But in humid air, a layer of green basic copper carbonate Cu2(OH)2CO3 can be generated on its surface, which is called verdigris. It is soluble in nitric acid and hot concentrated sulfuric acid, and slightly soluble in hydrochloric acid. It is easily corroded by alkali.

T2 is pure copper, also known as red copper. Red copper has good electrical conductivity, thermal conductivity, corrosion resistance and processing properties, and can be welded and brazed. It contains fewer impurities that reduce electrical and thermal conductivity. Trace amounts of oxygen have little effect on electrical and thermal conductivity and processing properties, but it is easy to cause "hydrogen disease" and is not suitable for processing (annealing, welding, etc.) and use in high temperature (such as >370℃) reducing atmosphere.
