Difference of Copper and Brass

November 13, 2018

Copper is a kind of pure copper, also known as red copper. As the name implies, the appearance is purple red, and the conductivity and plasticity are better, but the strength and hardness are worse. It is easy to stick a knife when machining.

Brass is an alloy of copper and zinc. As the name implies, the appearance is yellow, with good electrical conductivity, plasticity and wear resistance.

 

 

 

 

The difference between red copper and brass:

 

1, The two can be distinguished by the naked eye, because the two colors are different.

 

2, The two contain different amounts of copper, copper is 100% copper (naturally pure when there is no pure, this is only said to be very high), brass is an alloy of zinc and copper, the same volume, copper content without red copper high.

 

3, Treated with acid, copper is not reactive, the color does not change. The zinc in the brass reacts with the acid, and as the zinc reacts, the color of the brass slowly turns red.

 

4, The copper texture is softer than brass, not easy to CNC machining. Here is a video show the processing of cnc machining.

 

 

 

5, Copper has good electrical conductivity and thermal conductivity, excellent plasticity, easy to hot and cold pressure processing, a large number of used in the manufacture of wires, cables, brushes, electric sparks, special electro-etched copper and other products requiring good electrical conductivity. Brass has strong wear resistance, brass is often used in the manufacture of valves, water pipes, air conditioning inside and outside machine connecting pipes and radiators etc.
