AA-8000 series alloys meet the requirements of ASTM B800, Standard Specification for 8000 Series Aluminum Alloy Wire for Electrical Purposes–Annealed and Intermediate Tempers.
These AA-8000 series alloys are the only solid or stranded aluminum conductors permitted to be used according to Article 310 of the 2014 National Electric Code*. The client told me that he received a call from someone in Kansas City. Due to low-quality workmanship at connections and the physical differences between aluminum and copper, high-resistance connections formed and became a fire hazard.Īs a response, aluminum alloys were developed to have creep and elongation properties more similar to copper. Im actually having the exact issue with a client of mine located in Dallas, TX. In the 1960s and 1970s, due to the high price of copper relative to aluminum, this grade of aluminum began to be popularly used for household wiring. AA-1350 has a minimum aluminum content of 99.5 percent. Aluminum is generally more inexpensive when compared to copper conductors.Īluminum conductors consist of different alloys known as the AA-1350 series and AA-8000 series. That means that a bare wire of aluminum weighs half as much as a bare wire of copper that has the same electrical resistance. Annealed copper wire used for electrical purposes meets the requirements of ASTM B3, Specification for Soft or Annealed Copper Wire.Įven though copper has a long history as the material of choice for conducting electricity, aluminum has certain advantages that make it attractive for specific applications.Īluminum has 61 percent of the conductivity of copper, but has only 30 percent of the weight of copper. In addition to copper’s superior conductivity, the metal contains great tensile-strength, thermal-conductivity and thermal-expansion properties. Comprometidos con el medio ambiente Rusal America y Cuprum anuncian alianza Green Aluminum. Cuprum rolling out US100mn for 3 aluminum extrusion mills. Commercially pure copper produced today may have higher IACS conductivity values as processing technology has improved over time.� The aluminum extruder cited power availability as a deciding figure in selecting the plants cite. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. According to this standard, commercially pure annealed copper has a conductivity of 100 percent IACS. Industry: Alumina and Aluminum Production and Processing, Primary Metal Manufacturing, Manufacturing, Aluminum extruded. Copper is a chemical element with the symbol Cu (from Latin: cuprum) and atomic number 29. The all-aluminum furniture is an industry that is strongly promoted by the country and will become a new field for wood grain effect product applications. The International Annealed Copper Standard (IACS) was adopted in 1913 to compare the conductivity of other metals to copper. With the exception of silver, copper is the most common conductive metal and has become the international standard. Copper was the conductor used in inventions such as the telegraph, telephone and electric motor. Its ductility and electrical conductivity were exploited by the early experimenters with electricity, such as Ben Franklin and Michael Faraday. Copper is one of the oldest known materials.
