Due to the difference in aluminum content, special aluminum bronze has higher strength and hardness closer to alloy steel than alloy steel, and is widely used in force structural parts, transmission parts, etc.0312 Special specification hexagonal copper rod S880 hollow brass tube S2050 Hollow hexagonal copper rod S2050QAl94 aluminum bronze plate , Corrosion-resistant aluminum bronze […]

1 user-defined feature function, wholesale copper clad aluminum wire two parts of the part module, mountain program drive sign, 861 office 06 blood, noodle factory 8. If you have any questions, ask the customer 1 to solve the problem of reviewing the manufacturability and assembly of the mold. The above-mentioned management and technical measures are adopted. […]

Its advantages are short process, simple equipment, fast factory construction, and low investment. The metal copper obtained by blast furnace smelting has a high impurity content and is black, so it is copper clad steel strips manufacturer called black copper. The three-stage method has good comprehensive utilization of materials, simple smoke composition, simple treatment, high crude […]

It has high strength and outstanding wear resistance. Very good, the machinability is acceptable, the welding is not easy to be fiber pure copper strip welded, and the pressure production under the hot state is outstanding. QAL7 plates, belts, and lines commonly used in China have high strength and elasticity, high corrosion resistance in the atmosphere, […]

, It’s amazing. This undoubtedly records the previous history of the time and has become the ‘living teaching material’ and ‘living cultural relics’ that now understand the changes of the previous history. Since the beginning of circulation in 1900, it was gradually replaced by paper-based corner ballots and nickel in the 1930s.. The practices of […]

What varieties of non-ferrous metals are there? Non-ferrous metal (non-ferrous metal), also known as non-ferrous metal in the narrow sense, is the general term for all metals except iron, manganese and chromium. According to the brief history, copper, lead, tin, gold, silver and iron are all prehistoric metals. Nonferrous metals in a broad sense also […]

Copper minerals and other minerals are polymerized to form copper ore, and the copper ore that is mined out becomes a copper concentrate with a higher copper grade after beneficiation. In individual copper deposits, the content of copper can reach 3% to 5%. As early as in prehistoric times, people began to dig open-pit copper […]

Surface mechanical rust inhibitor treatment; surface chemical rust inhibitor treatment; surface electrochemical rust inhibitor treatment; spraying polymer (physical rust inhibitor treatment); other physical methods of rust inhibitor treatment. Surface mechanical rust inhibitor treatment is usually only used as a rust preventive treatment method, including sand blasting, shot blasting, sweeping or polishing, to provide a uniform, […]
