Copper alloy () is an alloy composed of pure copper as a base and one or several other elements added to it. Pure copper is purple-red, also known as copper. The density of pure copper is ., the melting point is ℃, and it has excellent electrical conductivity, thermal conductivity, ductility and corrosion resistance. It is mainly used to make electrical equipment such as generators, busbars, cables, switchgear, and transformers, as well as thermal conductive equipment such as heat exchangers, pipes, and flat-plate collectors of solar heating devices. Commonly used copper alloys are divided into brass, bronze, and white copper.
Brass is a copper alloy with zinc as the main added element. It has a beautiful yellow color and is collectively called brass. Copper-zinc binary alloy is called ordinary brass or simple brass. Brass with more than three elements is called special brass or complex brass. Brass alloys containing less than % zinc are composed of solid solutions and have good cold working properties. For example, brass containing % zinc is often used to make cartridge cases, commonly known as cartridge case brass or 73 brass. Brass alloys containing zinc between ~% are composed of solid solutions, among which the most commonly used is 64% zinc-containing brass. In order to improve the performance of ordinary brass, other elements are often added, such as aluminum, nickel, manganese, tin, silicon, lead, etc. Aluminum can improve the strength, hardness and corrosion resistance of brass, but reduces the plasticity. (Dongguan Jisheng Copper and Aluminum Wholesale-) It is suitable for use as condensation tubes and other corrosion-resistant parts for sea vessels. Tin can improve the strength of brass and its corrosion resistance to seawater, so it is called naval brass and is used for ship thermal equipment and propellers. Lead can improve the cutting properties of brass; this kind of easy-cut brass is often used as watch parts. Brass castings are commonly used to make valves and pipe fittings. Jisheng Company
Bronze originally refers to copper-tin alloy. Later, copper alloys other than brass and white copper are called bronze, and the name of bronze is often preceded by the name of the first major added element. Tin bronze has good casting properties, good friction reduction properties and good mechanical properties, and is suitable for manufacturing bearings, worm gears, gears, etc. Lead bronze is a widely used bearing material in modern engines and grinding machines. Aluminum bronze has high strength, good wear resistance and corrosion resistance, and is used to cast high-load gears, bushings, marine propellers, etc. Beryllium bronze and phosphor bronze have high elastic limit and good electrical conductivity, and are suitable for manufacturing precision springs and electrical contact components. Beryllium bronze is also used to manufacture non-sparking tools used in coal mines, oil depots, etc. Jisheng Company
Characteristics of pure red copper: high purity, fine structure and extremely low oxygen content. No pores, trachoma, loose conductivity, excellent electro-etched mold surface precision, heat treatment process, electrode non-directional, suitable for fine grinding, performance is comparable to Japanese pure red copper, the price is more affordable, and it is the first choice product to replace imported copper. .%＜Conductivity/Hardness
.Characteristics of chromium copper: good electrical and thermal conductivity, high hardness, wear resistance and explosion resistance, commonly used as conductive blocks. It has good uprightness and does not bend when thinly sliced.
.Characteristics of beryllium copper: Beryllium copper is a supersaturated solid solution copper-based alloy. It is a non-ferrous alloy with a good combination of mechanical properties, physical properties, chemical properties and corrosion resistance. After solid solution and aging treatment, it has high performance comparable to that of special steel. Strength limit elastic limit yield limit and fatigue limit. At the same time, it has high electrical conductivity, thermal conductivity, high hardness and wear resistance, high creep resistance and corrosion resistance. It is widely used in manufacturing various types of mold inserts to replace steel, making high-precision molds with complex shapes, welding electrode material die-casting machines (followed by W-) Injection molding machine punches are wear-resistant and corrosion-resistant, and beryllium copper strips are used in micromotor brushes, mobile phone batteries, computer connectors, various switch contact springs, clips, washers, diaphragms, membrane closures and other products. It is an indispensable and important industrial material in the construction of the national economy. Density./Hardness-r Electrical conductivity% Tensile strength Thermal conductivity/.℃
