The difference between red copper and brass

Can be distinguished by appearance, composition, strength and density, melting point, hardness. 1, Appearance: brass: light golden yellow, glossy, red copper: rose red, glossy. 2, composition: brass: copper content is about 60%, zinc content is about 40%, individual grades contain about 1% lead, there are impurities. Red copper: The content of copper is 99.9%. 3, strength: brass strength is high, red copper strength is low. 4. Density: The density of brass is 8.93g/cm3. The lining of mechanical bearing bush is made of brass because it is wear-resistant and is also commonly used to make valves and pipe fittings. Red copper, also known as red copper, has a density of 7.83g/cm3, a melting point of 1083 degrees, and is not magnetic. 5. Brass is harder than copper. 6. Copper has a higher melting point than brass
