NRE Copper Powder, Purity : 99.9%

Copper is a chemical element with the symbol Cu (Latin: cuprum) and atomic number 29. It is a soft, malleable and ductile metal with 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 component of various metal alloys such as Sterling silver used in jewelry, cupronickel used to make hardware and marine coins, and is constantly used in large gauges and thermocouples. For temperature measurement.

Copper is one of the few metals that can occur naturally in a metal that can be used directly (native metals). This led to very early human use in different regions, from c. 8000 BC Thousands of years later, it was the first fusion of sulfide, c metal ore. 5000 a. C., the first metal to be molded into a mold, c. 4000 BC and the first metal to be bound with another metal for purpose, tin, to create bronze, c. 3500 BC
