A brief introduction to the characteristics of copper: copper is industrial pure copper, named for its purple-red color. Chinese copper processing materials can be divided into four categories: ordinary copper, oxygen-free copper, deoxidized copper, and special copper (arsenic copper, beryllium copper, silver copper) with a small amount of alloying elements. The conductivity and thermal conductivity of copper are second only to silver and are widely used in the production of conductive and heat-conductive equipment. Copper is used in the chemical industry for its good corrosion resistance in the atmosphere, seawater and certain non-oxidizing acids (hydrochloric acid, dilute sulfuric acid), alkalis, salt solutions and various organic acids (acetic acid, citric acid). In addition, copper has good weldability and can be processed into various semi-finished products and finished products through cold and thermoplastic processing.
 
Brief introduction of the characteristics of brass: Brass-based copper-based alloy with zinc as the main alloying element, named after the yellow color. Brass has beautiful color, good process and mechanical properties, high conductivity and thermal conductivity, corrosion resistance in the atmosphere, fresh water and sea water, easy cutting and polishing, good weldability and low price. Commonly used in the production of conductive, heat-conducting components, corrosion-resistant structural parts, elastic components, daily hardware and decorative materials, etc., a wide range of uses.

What is the comparison between copper and brass?
 
Comparison of the density of copper and brass: brass density is greater than copper

The copper has a density of 7.83 g/cm3, a melting point of 1083 degrees, and is non-magnetic. Good electrical conductivity, thermal conductivity and corrosion resistance, toughness; brass density (8.93g/cm3) and mechanical bushing lining, wear-resistant!
 
Comparison of the characteristics of copper and brass: the machinability of brass is better than that of copper

Ordinary brass is a Cu-Zn alloy, which generally contains about 50% to 80% copper. The hardness is larger than that of copper, but it is poor in electrical conductivity and thermal conductivity. In addition, there are some special brass, including: aluminum brass, iron brass, lead brass and so on. In general, brass has better cutting performance than copper (copper is easy to stick); in non-cutting, copper has less deformation resistance and is easier to form.
