What are the characteristics of brass and copper, and what are the differences in their uses?
Brass is an alloy of copper and zinc. If it is only composed of copper and zinc, it is called ordinary brass. If it is composed of more than two elements, it is called special brass. For example, copper alloys composed of lead, tin, manganese, nickel, lead, iron and silicon have strong wear resistance. Special brass, also called special brass, has high strength, high hardness and strong chemical resistance. And a cutting machine. Soft texture and strong wear resistance. Brass seamless pipes can be used in heat exchangers and condensers, low-temperature pipes, submarine pipelines, making plates, bars, pipes, castings, etc. The copper content is 62% ~ 68%, so it has strong plasticity and can be used to make pressure-resistant devices.
Copper is named for its purplish red color. It is not necessarily pure copper, and sometimes a small amount of deoxidizing elements or other elements are added to improve the material quality and efficiency. Therefore, it is also classified as copper alloy. China red copper processing materials can be divided into: ordinary red copper (T 1, T2, T3, T4), oxygen-free copper (TU 1, TU2 and high purity, vacuum oxygen-free copper), deoxidized copper (TUP, TUMn) and special copper (arsenic copper, tellurium copper, silver) containing a small amount of alloying elements. It is widely used to manufacture electrical and thermal conductivity equipment. Red copper has good corrosion resistance in atmosphere, seawater, some non-oxidizing acids (hydrochloric acid, dilute sulfuric acid), alkali, salt solution and various organic acids (acetic acid, citric acid), and is used in chemical industry. In addition, red copper has good weldability and can be made into various semi-finished products and finished products through cold working and thermoplastic processing. In the 1970s, the output of copper surpassed other products.
What are the classifications of brass?
Brass can be divided into ordinary brass and special brass.
(1) Ordinary brass. This is an alloy of copper and zinc.
Classification of common brass: When the zinc content is less than 39%, zinc can be dissolved in copper to form single-phase A, which is called single-phase brass. It has good plasticity and is suitable for hot pressing and cold pressing. When the content of zinc is more than 39%, there are single phase and B solid solution mainly composed of copper and zinc, which is called biphase brass. B reduces plasticity and increases tensile strength, which is only suitable for hot pressing. If the mass fraction of zinc continues to increase and the tensile strength decreases, it will be useless.
Brass alloy with zinc content below 36% is composed of solid solution, which has good cold working efficiency. For example, brass containing 30% zinc is often used to make shell casings, commonly known as shell brass or 73 brass. Brass alloy with zinc content between 36% and 42% is composed of solid solution, among which brass with zinc content of 40% is the most commonly used.
Generally speaking, single-phase brass is used for cold deformation and double-phase brass is used for hot deformation.
(2) Special brass. A multicomponent alloy composed of ordinary brass and other alloying elements is called brass. Usually added elements are lead, tin, aluminum and so on. , which can be called lead brass, tin brass and aluminum brass. The purpose of adding alloying elements. Mainly to improve tensile strength and manufacturability.
Special brass is classified into:
Lead brass: Lead is actually insoluble in brass and distributed on grain boundaries as a free particle. Lead brass can be divided into α and (α+β) according to its structure. α lead brass can only be cold deformed or hot extruded because of its harmful effect and low high temperature plasticity. (α+β) lead brass has good high temperature plasticity and can be forged.
Tin brass: adding tin to brass can obviously improve the heat resistance of the alloy, especially the ability to resist seawater corrosion, so tin brass is called "navy brass"
Manganese brass: Manganese has great solubility in solid brass. Adding 1% ~ 4% manganese to brass can significantly improve the strength and corrosion resistance of the alloy without reducing its plasticity.
Iron brass: In iron brass, iron precipitates in the form of iron-rich particles, which are used as crystal nuclei to refine grains and prevent recrystallization grains from growing, thus improving the mechanical and technological efficiency of the alloy.
Nickel brass: Nickel and copper can form a continuous solid solution, significantly expanding the α phase region. Adding nickel to brass can significantly improve the corrosion resistance of brass in the atmosphere and seawater. Nickel can also increase the recrystallization temperature of brass and promote the formation of finer grains.

What are the benefits of flavonoids to human body?
Hello: You may have heard of many flavonoids. Now, this word appears more and more frequently. The following is some knowledge about its cancer prevention and other uses. According to the American Traditional Science Dictionary, some water-soluble plant pigments are beneficial to health. Flavonoids are polyphenols with antioxidant, anti-inflammatory and antiviral properties. They also help keep small blood vessels and connective tissue healthy. Some people are studying the possibility of treating cancer with it. In addition, it is also called bioflavonoids. Flavonoids, as plant pigments, provide colors for fruits and vegetables containing them. They are also powerful antioxidants, which can slow down the oxidation process of fruits, vegetables and fruit skins. These antioxidants play the same role in the body and can protect the cell membrane from free radicals. Why do we need it? Dr. Joe Vinson, a chemistry professor at Scranton University, explained: "Flavonoids protect cells from free radicals like antioxidants." . Free radicals are considered to be the root cause of degenerative diseases and easy aging. Flavonoids can prevent the oxidation of low density lipoprotein or bad cholesterol and prevent plaque accumulation. Flavonoids improve insulin sensitivity, which is good news for diabetics. Flavonoids have anti-inflammatory effect and help to relieve pain. They are usually used to treat low back pain and leg pain. The anti-inflammatory effect is also beneficial to different types of facial conditions, from small bites to chronic facial diseases, such as eczema. Flavonoids can also relieve joint pain and muscle pain, and rheumatoid arthritis. Flavonoids help prevent the release of histamine in allergic reactions. Histamine is the cause of tears, runny nose, congestion related to different types of allergies, dyspnea and asthma. In addition to these benefits, people are still studying its potential benefits in preventing heart disease, cancer and stroke and preventing cataracts. It has been proved that it can promote nitric oxide, improve blood vessel elasticity and make blood flow easier. Flavonoids can also reduce platelet coagulation and prevent heart disease and stroke. Where can I get them? Flavonoids can be found in fruits and vegetables, such as flower seeds, dried fruits, tea, cocoa, pine bark and buckwheat. The best food sources are cocoa, green tea, red wine, apples and onions. Citrus fruits are also rich in flavonoids, especially the white material content between citrus peel and pulp is the largest.
What is the function of zinc in brass?
Zinc can adjust the plasticity of copper. When the zinc content is lower than 39%, the plasticity of copper increases, which is suitable for cold and hot pressure processing. When the zinc content is more than 39%, the plasticity decreases and the tensile strength increases, so it is only suitable for hot working.
