Brass and red copper which hardness tall?

Copper has good electrical conductivity, thermal conductivity and ductility, etc., is widely used in cables and electrical and electronic components, because of its low melting point, easy to remelt, resmelting, is also a relatively environmentally friendly material. The most widely used are brass and copper.
Brass and red copper which hardness tall?
1. The universal characteristic of metal materials is that the hardness of pure metal is lower than that of its alloy, which has high hardness and low melting point. And anaerobic copper and copper are pure copper, but the purity is different, the purity of anaerobic copper is higher, the purity of copper can reach 99.9%~99.99%(some differences between different brands) copper contains very few impurities, so the purity of anaerobic copper is the highest, but also the softest, copper slightly hard (close to anaerobic copper), brass is the hardest.
2. Copper has a characteristic, will soften hardness after heat treatment, and after the cold working can harden (cold work hardening), since the stiffness of the non-ferrous metal and alloy and influenced by the composition, nameplate, impurities, and with state and lattice structure, has much to do, so generally there are few specific hardness data, only qualitative description.
3. What is the hardness of purple copper? Copper, density (7.83g/ cm3) melting point 1083 degrees, copper content up to 99.9%, it is not magnetic. With good electrical conductivity, thermal conductivity and corrosion resistance, copper is named for its purplish red color. Copper has good corrosion resistance in air, sea water and some non-oxidizing acid, alkali, salt solution and a variety of organic acids. It is used in chemical industry.
