Brass with zinc because the main element of the copper alloy, with beautiful yellow, collectively said as brass. Copper zinc binary alloy is named ordinary brass or simple brass. Brass with quite three yuan is termed special brass or complex brass. Brass alloys containing but 36% zinc are composed of solid solutions and have good cold working performance. as an example, brass containing 30% zinc is often wont to make shell casings, commonly called shell brass or seventy-three brass. Brass alloys with zinc content between 36 and 42% are composed of and solid solutions, of which the foremost commonly used is hexagonal brass with zinc content of 40%. so as to boost the performance of ordinary brass, other elements are often added, like aluminum, nickel, manganese, tin, silicon, lead and then on. Aluminum can improve the strength, hardness and corrosion resistance of brass, but reduce the plasticity, so it’s suitable for Marine condensing tubes and other corrosion resistant parts. Tin can improve the strength of brass and corrosion resistance to seawater, so it’s called Tobin bronze, used for ship thermal equipment and propellers. Lead can improve the cutting performance of brass. This free cutting brass is commonly used as a clock part. Brass castings are often accustomed make valves and plumbing fittings.
Bronze originally refers to copper-tin alloy, later copper alloys except brass and white copper are all called bronze, and bronze is usually preceded by the name of the primary major added element. Tin bronze has good casting performance, friction reduction performance and mechanical properties, suitable for manufacturing bearings, gear wheel and then on. Lead bronze may be a bearing material widely utilized in modern engines and grinding machines. copper-base alloy has high strength, good wear resistance and corrosion resistance. it’s used for casting gears, bushings and Marine propellers with high load. bronze and phosphatic bronze have high elastic limits and good electrical conductivity, making them suitable for the manufacture of precision springs and tangency elements. bronze is additionally utilized in the manufacture of sparkless tools employed in coal mines and oil detankers.
A copper alloy with nickel because the main additive element. Cu-ni binary alloy is named ordinary white copper; Add manganese, iron, zinc, aluminum and other elements of the white copper alloy called complex copper. Industrial white copper is split into structural white copper and electrical white copper two categories. The structure of white copper is characterized by good mechanical properties and corrosion resistance, beautiful color. The white copper is widely employed in precision machinery, chemical machinery and Marine components.
Copper gets its name from its red color. it’s not necessarily pure copper, and sometimes alittle amount of deoxidation elements or other elements are added to boost the fabric and performance, so it’s also classified as a copper alloy. consistent with the composition of Chinese copper processing materials are often divided into four categories: ordinary copper, oxygen-free copper, deoxidized copper, special copper with alittle amount of alloying elements. Copper is second only to silver in conductivity and thermal conductivity, and is widely utilized in the assembly of electrical and thermal conductive equipment. Copper within the atmosphere, sea water and a few non-oxidizing acids, alkali, salt solution and a spread of organic acids (acetic acid, citric acid), has good corrosion resistance, employed in industry. additionally, red copper has good weldability, is made into a range of semi-finished products and finished products by cold and thermoplastic processing.
