Aluminum alloy Eight series: the 8000 series aluminum alloy is more commonly used 8011 belongs to other series, most of the application for aluminum foil, aluminum rod production is less commonly used. 9 series :9000 series aluminum alloy is a standby alloy. Aluminum alloy pure aluminum products pure aluminum products are divided into two categories: refined products and pressure processed products. The former is denoted by chemical composition Al, while the latter is denoted by hanyu pinyin LG (for aluminum and industrial use). Pressure machined aluminum alloy aluminum alloy casting aluminum alloy casting aluminum alloy (ZL) is divided into four categories according to the main elements besides aluminum, including silicon, copper, magnesium and zinc. The codes are 100, 200, 300 and 400 respectively. 1. Scope this standard specifies the status code for deformed aluminum alloys. This standard applies to aluminum and aluminum processing products. 2.1 the basic status code shall be indicated by a capital letter. 2.2 subdivision status codes are represented by the basic status codes followed by one or more Arabic numerals. 2.3 basic state code basic state is divided into 5 code name description and application F free machining state is applicable to the molding process, for the processing hardening and heat treatment conditions without special requirements of the product, the mechanical properties of the state of the product is not specified.
