Bare copper tape is often used as a conductor of pure copper. The main characteristic of the bare copper tape is that it has good electrical conductivity and very stable signal transmission. It is recognized as the best conductor for shielding other than gold conductors in the industry. In the copper industry, bare copper tape is considered to be a pure copper conductor that has not undergone any plating processing.
Relatively speaking, the copper content of the oxygen-free copper strip is greater than 99.97%. Compared with another feature, the thermal conductivity and chemical resistance of bare copper are better. The adhesive made of bare copper can be used for surface protection of many substances.
In terms of application, oxygen-free copper tape is widely used in electronics, home appliances, aviation and automobile manufacturing industries. In the electronics industry, for example, many electronic products (such as mobile phones, computers, digital cameras, and mobile hard disks use oxygen-free copper). In the home appliance industry, the use of oxygen-free copper is more extensive, and products such as televisions, washing machines, refrigerators, and air conditioners are inseparable from the use of oxygen-free copper belts. In the field of aviation and automobile manufacturing, the application of oxygen-free copper tape is even more ubiquitous. The most commonly used characteristics of oxygen-free copper are its good moisture resistance and chemical resistance. Of course, its excellent thermal conductivity is also one of the important reasons why it is loved by many products.
Brief Introduction of Manganese Brass Band: Manganese brass is a complex brass with manganese as the main added element. The effect of manganese on reducing the a zone of copper-zinc alloy is minimal, and it has little effect on the structure of brass. Manganese can significantly improve the corrosion resistance of brass in the atmosphere, seawater, chloride and superheated steam. Manganese plays the role of solid solution strengthening in brass, which can improve the strength and hardness. The content of manganese in manganese brass is usually 1% to 4%. When it exceeds 4%, the elongation and impact toughness are somewhat reduced.
Characteristics and uses of manganese brass
Manganese brass belt is widely used in ships and marine engineering due to its quite good strength and cold and hot processing properties. It can also be used as a wear-resistant material for high-pressure pump friction pairs and automotive synchronization gear rings. The main characteristics and specific uses of commonly used manganese brass are shown in the table below.
HMn62-3-3-0.7 High strength, good thermoplastic parts, good abrasion resistance, corrosion resistance, easy cutting processing pipes, bars, application examples: car synchronizer ring
HMn58-2 has very good strength and hardness, wear resistance, corrosion resistance, and good workability. Pipes and bars, application examples: marine pumps, valves, etc.
HMn57-3-1 has high strength, good processing performance, seawater corrosion resistance pipe, beech material, application examples: structural parts, friction pairs
HMn59-2-1-0.5 has high strength and hardness, wear resistance, corrosion resistance, and good workability. Pipes and bars, application examples: structural parts, wear-resistant parts, etc.
