Which one is harder, brass or copper?

 

    Copper has good electrical conductivity, thermal conductivity and ductility. It is widely used in cables and electrical and electronic components. Because of its low melting point, it is easy to remelt and re-smelt. It is also a relatively environmentally friendly material. Among them, brass and red copper are widely used. Many companies do not know which brass or red copper has high hardness, which leads to errors in the production. The following technicians will introduce to you which hardness of brass parts or red copper is high?

 

brass

 

  What is copper?

 

  Purple copper is named for its purple-red color. It is a relatively pure copper. It is not necessarily pure copper. Generally, it can be approximated as pure copper. It has good electrical conductivity and plasticity, but its strength and hardness are worse.

 

  What is brass? 

 

Brass is an alloy composed of copper and zinc. Brass composed of copper and zinc is called ordinary brass. If it is a variety of alloys composed of more than two elements, it is called special brass. Brass is Copper-zinc alloy has excellent plasticity, high strength and good corrosion resistance.

 

  Which is harder, brass or copper?

 

  1. The general feature of metal materials is that the hardness of pure metal is lower than that of its alloy, which has high hardness and low melting point. Oxygen-free copper and red copper parts are both pure copper, but the purity is different. The purity of oxygen-free copper is higher, and the purity of red copper can also reach 99.9%~99.99% (different grades have some differences). Red copper contains very few impurities, so there is no Oxygen copper has high purity, soft, red copper is slightly hard (close to oxygen-free copper), and brass is hard.

 

2. There is another feature of copper material. The hardness will become soft after heat treatment, and it will become hard after cold working (cold work hardening). Due to the influence of the hardness, composition, brand and impurities of non-ferrous metals and alloys, it is also affected by the state, crystal The lattice structure has a lot to do with it, so there are generally few specific hardness data, which can only be described qualitatively.

 

3. What is the hardness of red copper? Red copper has a density (7.83g/cm3), a melting point of 1083 degrees, and a copper content of 99.9%. It is non-magnetic. It has good electrical conductivity, thermal conductivity and corrosion resistance, and the copper is purple due to Named for the red color. The electrical conductivity and thermal conductivity of copper is second only to silver, and it is widely used in the production of electrical and thermal conductivity equipment. Copper is used in the atmosphere, seawater, and some non-oxidizing acids, alkalis, salt solutions and various organic acids. , Has good corrosion resistance, used in the chemical industry.

 

4. The density of brass (8.93g/cm3) is used for mechanical bearing lining, wear-resistant, brass "density is greater than copper" copper-based alloy with zinc as the main alloying element, copper is about 60%; zinc is about 40% ; Individual grades contain about 1% of lead, which is impurity. Named because it is often present, brass is beautiful in color, has good craftsmanship and mechanical properties, has a certain degree of corrosion resistance, and has lower electrical conductivity than copper.

 

Which one of brass or copper has higher hardness, I believe everyone will understand from the above introduction. When manufacturing wires and cables, of course, red copper is more preferable. Its conductive resistance is small, and it is more suitable for conductors. The hardness is less than brass, making the wires and cables more flexible. It is easier to operate during use, and at the same time there are fewer impurities, which increases the conductivity of copper.

How does an auto parts company develop

With the party branch as the core of the bank's guidance, the socialist state-owned enterprise must have a strong and combative party organization, so that the majority of employees can have cohesion and the enterprise can compete with the outside world. The three are complementary and mutually supportive. Promoted. The key to the problem lies in whether the party organization has combat effectiveness. If the leadership team has fully played its role, it can unite the masses closely and enable the enterprise to forge ahead toward a common goal. In turn, if the mass foundation is good and the enterprise situation is good, the party organization can be more effective. Work well. The success of Zhanjiang Auto Parts Company fully illustrates this point. They mainly focused on the following tasks: The first is to enhance the combat effectiveness of the leadership team. Party branches and leading cadres are required to have a higher political level and profess...

The heat treatment process of auto parts consumes a lot of energy

  The heat treatment process of auto parts consumes a lot of energy, so it is necessary to work to reduce the energy consumption in each treatment stage, which includes furnace improvement, carburizing process control, quenching medium, cooling rate, etc. However, the operation of these processes is directly related to the properties and hardenability of the processed steel with different compositions. In order to meet the requirements of advanced heat treatment technology, various types of steel have been studied from smelting. The improvement of these steels and related technology has greatly improved the performance and processing productivity of auto parts. The chemical composition and hardenability of steel are the key factors to obtain the best heat treatment effect for auto parts. In order to obtain high-quality small-modulus gears in automotive products, it is necessary to carefully control the surface and core hardness of the gears. The develo...
