The difference between aluminum alloy cable and ordinary cable

[China Aluminum Network] 1. Definition of Aluminum Alloy Cable

Aluminium alloy power cable is a new type material power cable with AA-8000 series aluminum alloy material as conductor, special pressing technology and annealing treatment, and advanced technology such as interlocking armoring technology.

2, the difference between alloy cable and ordinary cable

Alloy cable uses AA-8000 series aluminum alloy conductor, while ordinary cable uses copper or pure aluminum as cable conductor.

3, why should we promote the use of alloy cable

At the same volume, the actual weight of an aluminum alloy is about one-third that of copper. According to this calculation, the same weight aluminum alloy cable is twice as long as the copper cable under the same electrical performance. Therefore, the weight of aluminum alloy cables at the same current carrying capacity is about half that of copper cables. The use of aluminum alloy cables instead of copper cables can reduce the weight of cables, reduce installation costs, and reduce equipment and cable wear, making installation easier.

4, the advantages of alloy cable over ordinary cable:

Conductivity: The conductivity of aluminum alloy is 61.5% that of the commonly used reference material copper IACS, and the carrying capacity is 79% of copper, which is superior to the pure aluminum standard.

Smco1:5 magnet is also named Smco5. Prorated with metallic samarium, cobalt and metallic praseodymium, are firstly those roughcasts with different properties and grades after series technology processing from melting, milling, and pressing to sintering in order. The (BH)max range is from 16 to 25, maximum working temperature 250 ℃. The physical character and ductibility of  Smco5 is better than Sm2Co17, so Smco5 is slightly easier to be machined thin thickness disc or ring wall and complex shapes while Sm2Co17 is more brittle. Magnetization magnetic field of  Smco5 is lower than Sm2Co17's. In general, Smco5 can be magnetized saturated by 4000Guass magnetic field. However, magnetizing Sm2Co17 with high Hcj value need more than 6000guass magnetic field. These days, prices of rare earth material improved significantly, and the level of rare earth material around the magnet is up to 40%.  For these reasons, the price of Smco5 is more expensive than Sm2Co17. According to different using circumstance, customers can choose SmCo5 or Sm2Co17 reasonably.
