Aluminum alloy cables are more reliable in terms of resistance to corrosion and flame retardants. AA8000 series aluminum alloy is made by adding rare earth, which is far better than pure metal in terms of erosion and flame resistance. At present, aluminum alloy cables have been used in the United States for more than 40 years. From the application to now, there has never been an erosion of aluminum alloy cables and a fire. It can be seen that the safety of aluminum alloy cables is relatively reliabl.
