What are the rules for metal stamping die scrap tube?

The Purpose Standardize the management of the scrapping of the company's metal stamping dies, prevent the loss of company assets, and formulate this system specially. Scope of application It is suitable for the management of the company's scrap molds. Definition If the molds listed in the assets of the company fall under one of the following circumstances, the use management department may apply for scrapping. 1. Molds that exceed the specified service life. 2. The mold is severely damaged by accidents or accidents, and molds that cannot be repaired or have no repair value. 3. Metal stamping dies that have not reached the service life, but due to safety, quality, efficiency and other issues, the repair still fails to meet the minimum requirements of the customer's product process or affects the production safety and efficiency. 4. Product customers have stopped placing orders or have not placed orders for molds in several years. 4. Responsibilities 1. Responsibilities of th

What errors may occur during CNC machining and CNC machining​?

 CNC machining and numerical control machining are a method to control the movement of machine tools and the production process of machining through computer digitization and information digitization. It is an intelligent numerical control device developed as an economical, high-speed, reliable, multi-functional, intelligent, and open structure. CNC machining is also an important indicator that can measure the continuous level and comprehensive ability of a safety technology, as well as the degree of modernization of related science and technology capabilities, especially in aviation, biology, medical and other high-tech cultural industries, and it is also a powerful indicator. reflect. So, what errors may occur during CNC machining and CNC machining? Let us understand together:   The use of approximate machining motion or approximate tool contours causes errors in the CNC principle of machining. The reason why it is called machining principle error is because of the error in machining

Which one is harder, brass or copper?

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?




  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.


Products that can process include: titanium-parts, stainless-steel-parts,magnesium-parts, zinc-parts,steel-parts, metal-parts,superalloy-parts, plastic-parts, car-parts, industrial-product,medical, anime-model, sla-3d-printing.
