Annealing temperature of copper wire drawing

The annealing temperature of copper wire drawing is 260-300℃, and the holding time is 65438±0h h.

Copper (Cuprum) is a metal element and a transition element, with chemical symbol Cu, English copper and atomic number 29. Pure copper is a kind of soft metal. When it is just cut, its surface is reddish-orange with metallic luster, and its simple substance is purplish red. Good ductility, high thermal conductivity and electrical conductivity, so it is the most commonly used material in cables, electrical and electronic components, and can also be used as building materials to form a variety of alloys. Copper alloys have excellent mechanical properties and low resistivity, among which bronze and brass are the most important. In addition, copper is also a durable metal, which can be recycled many times without damaging its mechanical properties.
