The dimensions of the billet, which is cylindrical or wire, are as follows:Length: 7300 mmDiameter: 250 mmThe existence of several copper mines in Iran and the Middle East and its export to other countries has made Iran a supplier of about 3% of the world's copper reserves
The cathode is sent to the foundry unit in the refinery and leaching. This unit consists of two parts, continuous and semi-continuous casting. Among the products of the semi-continuous casting, the sector is slabbed (copper flat ingots) which are produced according to ASTM B5 standard.
Generally, the dimensions of slabs in the form of flat sheets are as follows:
- Length: 7300 mm
- Width: 660 mm
- Thickness: 127 mm
Billets:
The cathode produced in the refinery and leaching is sent to the casting unit. This unit consists of two parts, continuous and semi-continuous casting. One of the products of the semi-continuous casting sector is billet (copper cylindrical ingot) which is produced according to ASTM B5 standard.
The dimensions of the billet, which is cylindrical or wire, are as follows:
- Length: 7300 mm
- Diameter: 250 mm
The existence of several Copper mines in Iran and the Middle east and its export to other countries has made Iran a supplier of about 3% of the world's copper reserves. For example, in the first seven months of 1995, about 200 kilograms of copper ingots were exported to other countries, which is about $ 1,193,376. If you are looking to buy or sell copper metal, the 20 iron system will be by your side in this field.
Economic efficiency! After the rise in copper prices, it happened that they preferred Aluminum wire to copper wire. The price of copper is higher than aluminum, while the equivalent amount of aluminum is 50% more than the area of copper, and this means exactly the economic cost.
But the high price of copper is not one hundred percent unreasonable. Unlike aluminum - which loses its performance and becomes dangerous when oxidized - copper does not lose its properties when oxidized and continues to work. Copper is a much safer choice for the electricity industry and of course, it has higher efficiency, high conductivity of copper makes it possible to use copper in power plants. Copper also has lower strength, which makes it more conductive.
In general, the main advantage of copper wire is its strength and flexibility. Ease of flexibility, wiring, and installation. The conductivity in copper is so high that you need small conductors and because of its physical strength, you will be sure that you have strong and safe connections. Also, the high flexibility of copper ensures that there is no risk of fracture on copper. The only drawback is that copper is expensive.
