Explore The Versatility Of Copper Bars – An Ideal Combination Of Value And Practicality

1. Fundamental principles and classification of copper bars

Copper bar is a type of metal material, which is a kind of copper material. Copper bars are produced from refined copper as raw element, that is heated, melted, homogenized, and drawn.

Copper Bar

Copper is an important industrial raw element and is also widely used in various fields, like electronics, construction, automobiles, and ships. Its element properties include good electrical conductivity, thermal conductivity, plasticity, and corrosion resistance, therefore it is commonly used.
The dimension and duration of Copper bar vary. The general diameter is between 1mm and 300mm, as well as the length is decided based on demand. Copper bars usually use electrolytic copper or fire-refined copper as raw materials and are processed through drawing or rolling processes. According to different processing methods, they can be split into several types, such as hot-rolled copper bars, cold-rolled copper bars, extruded copper bars, etc. They can also be jointly processed along with other materials to form more complex parts.

2. Characteristics and advantages of copper bars

1. Good electrical conductivity: Copper is a good conductor. Metal copper strips have relatively good electrical conductivity and can conduct electrons. They are suitable for manufacturing electrical appliances, wires, etc.
2. Wide applicability: Metal copper strip is really a commonly used material ideal for manufacturing building materials, auto parts, mechanical equipment, as well as other fields.
3. Strong corrosion resistance: Metal copper strips have good corrosion resistance and therefore are not easily impacted by oxidation. They are suitable for areas with high environmental requirements, like manufacturing chemical instruments.
4. Good thermal conductivity: The thermal conductivity of copper is also very good. The thermal conductivity of metal copper strips is comparatively good, and it is suitable for manufacturing heat exchangers as well as other areas that need to conduct heat energy.

3. Application scope of copper strips

The excellent electrical and thermal conductivity of copper strips makes them widely used within the power and telecommunications industries, engineering, transportation, aerospace as well as other fields. When copper strips are utilized as raw materials for copper alloy products, they are commonly used in the metal processing and modeling industries.

1. Electrical: Manufacturing of electrical equipment components like wires, cables, transformers, and motors.
2. Construction: Making roofs, doors, windows, pipes and other building and decoration components.
3. Clocks: Produces watch parts, like dials, clock hands, etc.
4. Automobile: Make automobile wires, brakes, water pumps as well as other parts.
5. Ships: Ship manufacturing, making propellers, pipes and other parts.

4. What to do when the copper becomes black?

Warm soap and water
First, dissolve a small bit of soap in warm water. After the soap is fully dissolved, soak the copper in warm, soapy water for half an hour. Scrub the copper clean, rinse it with clean water, and finally, wipe it clean having a towel.
Diatomite
Stir diatomaceous earth, oxalic acid, and water into a paste in a ratio of 6:1:4, apply it on the surface from the copper, and let it dry naturally. Then, clean the diatom paste on the copper with water and wipe it dry with a cotton cloth.
Sea salt
First, melt the wax, combine it with sea salt, and mix it evenly. Then, dip a clean cotton cloth in to the wax mixed with sea salt, wipe the blackened area of the copper surface, and after that wipe it off with clean water.
Alkaline water
Soak the blackened copper in alkaline water. Copper turns black because of acid corrosion in the air, so using alkaline cleaning agents is very effective.
Talcum powder
Talcum powder can also remove black things on the surface of copper. Wipe the copper bracelet vigorously with talc powder and you can notice that the copper returns to its golden color.
Vinegar
Use a dry cloth soaked in vinegar to wipe back and forth around the blackened area on the copper surface, and finally, rinse it with clean water and dry it.
Sawdust
Mix sawdust, wheat bran, talcum powder, and vinegar in proportion and apply on the copper. Rinse with clean water after drying.
Flour
Mix the flour, fine wood, and vinegar evenly and put it on on the blackened areas of the copper surface. After drying, wipe it clean having a soft cloth and clean water.
Tooth powder
The cleaning power of toothpaste is a lot stronger than that of toothpaste, so using toothpaste can also have a certain cleaning effect on copper surfaces.

5. Cost of copper bars

The cost of copper bars is affected by many factors, including market supply and demand, copper purity, production technology, and regional differences. Therefore, the cost of copper bars changes dynamically. If you need to understand the real-time price of copper bars, it is suggested to consult the local metal exchange or copper bar supplier.
