 (A) copper alloy Description: 

 Was added to pure copper for some of the alloying elements (such as zinc, tin, aluminum, beryllium, manganese, silicon, nickel, phosphorus, etc.), to form a copper alloy. Copper alloy having a good electrical conductivity, thermal conductivity and corrosion resistance, while having a high strength and wear resistance. 

 According to the different components, copper alloy into brass and bronze. 

 1. Brass is zinc as the main alloying elements copper alloy. According to the chemical composition, the brass is divided into two kinds of ordinary copper and special brass. 

 (1) ordinary ordinary brass brass is a binary alloy of copper and zinc. Plate, bar, wire, pipes and deep drawing parts, such as condenser, heat pipes and machinery, electrical parts, etc., suitable for the manufacture of plastic good. The average copper content of the brass of 62% and 59% can also be cast, called a cast brass. 

 (2) in order to obtain higher strength, corrosion resistance and good casting performance, the special brass, aluminum, silicon, manganese, lead, tin, copper and zinc alloy elements on the formation of a special brass. Such as leaded brass, tin, brass, aluminum, brass, silicon brass, manganese brass. 

 Lead brass excellent cutting performance, wear resistance, widely used in the manufacture of watch parts, bearings and bushings casting production. Tin brass corrosion resistance, widely used in the manufacture of parts of ships. Aluminum brass, aluminum can improve the strength and hardness of brass, to improve the corrosion resistance in the atmosphere for manufacturing a corrosion-resistant parts, aluminum, brass. 

 Silicon in silicon brass copper can improve the mechanical properties, wear resistance corrosion resistance, silicon brass is mainly used in the manufacture of parts of ships and chemical mechanical parts. 

 2. Bronze 

 Originally referred to a copper-tin alloy, bronze are used to call industrial copper alloy containing aluminum, silicon, lead, beryllium, manganese bronze, bronze is actually composed of tin bronze, aluminum bronze, aluminum bronze, beryllium copper, silicon bronze , lead bronze. The bronze also is divided into the pressure processing bronze casting bronze two categories of. 

 (1) tin bronze with tin as the main alloying elements copper-based alloy, said tin bronze. Industrial use tin bronze, most of the tin content is between 3% to 14%. The tin content of less than 5% tin bronze is suitable for cold working use; tin content is from 5% to 7% tin bronze suitable for thermal processing; the tin bronze adapted Casting tin content greater than 10%. Tin bronze is widely used in industries such as shipbuilding, chemical, mechanical, instrumentation, primarily for the manufacture of bearings, bushings and other wear-resistant parts and springs and other elastic components, and resist, anti-magnetic parts, etc.. 

 (2) aluminum bronze aluminum as the major alloying elements copper-based alloy, said aluminum bronze. The mechanical properties of aluminum bronze than brass and tin bronze. The practical application of the aluminum bronze of aluminum content of between 5% to 12%, aluminum is the best 5% to 7% of aluminum bronze plastic, suitable for cold working. The aluminum content is greater than 7% to 8%, the strength is increased, but the plastic is a sharp decline, so much after the cast or by thermal processing. Aluminum bronze wear resistance and corrosion resistance than brass and tin bronze in the atmosphere, sea water, sea water, carbonic acid, and most organic acids. Aluminum bronze manufacturing gear, bushings, worm gear and high strength anti-wear parts and high corrosion resistance of the elastic element. 

 (3) to beryllium, beryllium copper as the basic elements of a copper alloy, said beryllium bronze. The amount of beryllium copper beryllium from 1.7% to 2.5%. The advantages of the elastic limit of the beryllium copper, have a high fatigue limit is excellent in wear resistance and corrosion resistance, has good electrical conductivity and thermal conductivity, but also having a non-magnetic, and does not produce sparks upon impact. Beryllium copper is mainly used for the important spring production of precision instruments, watches and clocks, gear, high-speed high pressure bearings, bushings, and electric welding electrodes, explosion-proof tools, mariner's compass and other important parts.
