Alloys in which silicon is the principal alloying element but other alloying elements such as copper and magnesium are specified . Alloys in which silicon is the principal alloying element . Alloys in which magnesium is the principal alloying element . Unused . Alloys in which zinc is the principal alloying element but other alloying elements such as copper and magnesium may be specified . Alloys in which tin is the principal alloying element . Unused Wrought aluminum. Superpurity aluminum is limited to certain chemical plant items flashing for buildings and other applications requiring maximum resistance to corrosion and or high ductility justifying high cost. Other alloys are Al-Mn Al-Mg Al-Mg-Si Al-Cu-Mg Al-Zn-Mg Al-Li and Al-Sn used as bearing materials particularly clad onto steel shells for automobile engines and similar applications . For wrought alloys a four-digit system is used to produce a list of wrought composition families as follows 1xxx. Controlled unalloyed compositions of 99 or higher purity are characterized by generally excellent resistance to attack by a wide range of chemical agents high thermal and electrical conductivity and low mechanical properties. For example 1100-O has a room-temperature minimum tensile strength of 75 MPa and a yield strength of 25 MPa. Iron and silicon are the major impurities. Commercial purity metal to is available in three purities and a range of work-hardened grades for a wide variety of general applications plus a special composition for electrical purposes. High-purity aluminum is used for many electrical and process equipment applications. The higher-purity members of the 1xxx group are used in equipment handling such products as hydrogen peroxide and fuming nitric acid. 2xxx. Alloys in which copper is the principal alloying element although other elements notably magnesium may be specified. This group involves the first age-hardening
