Due to their excellent comprehensive properties, aluminum and aluminum alloys are widely used in transportation, architectural decoration, machinery manufacturing, packaging and printing, etc. noodle. Excellent processing properties ensure that aluminum and aluminum alloys can be produced by casting, forging, rolling, punching, pressing and other methods to produce plates, strips, foils, tubes, bars, profiles, and wires. Aluminum and aluminum alloys are currently the preferred materials for green, environmental protection and lightweight. Continued strong demand in aluminum and aluminum alloy applications With the continuous expansion of the scope of application and application, the technology update cycle is significantly shortened, the variety of products continues to increase, and nouns and terms emerge in an endless stream. GB/T 8005 aluminum and aluminum alloy terminology series standards aim to standardize aluminum and aluminum alloys (product and processing technology, chemical analysis, surface treatment management, recycling) terms to facilitate the trade of aluminum and aluminum alloy products, consisting of four parts.

1.Products and processing technology;

2.Chemical analysis;

3.Surface treatment;

4.Recycled aluminium. In 1987, my country issued GB/T 8005-1987 "Terminology of Aluminum and Aluminum Alloy" for the first time, which stipulated Terms and definitions for mechanically processed products, processes and treatments..2008, with reference to ISO 3134.1985 and EN12258-1.1998 published GB/T 8005.1-2008 "Terminology of aluminum and aluminum alloys - Part

1.Products and processing technology"; refer to ISO 7583.1986 release GB/T 8005.3-2008 "Terminology of aluminum and aluminum alloys - Part

3.Surface treatment". In.2011, modified to adopt EN12258-2. In.2004, GB/T 8005.2-2011 "Terminology of Aluminum and Aluminum Alloys Part

2.Chemical Analysis" was released..2019, refer to EN12258- 1.2012 released GB/T 8005.1-2019 "Terminology of Aluminum and Aluminum Alloys Part

1 Scope

Part 4 of China's national terminology series for aluminium, covering aluminium scrap. Recycling aluminium takes about five per cent of the energy of smelting it from ore, which makes secondary aluminium one of the genuinely large decarbonisation levers available to industry - and the constraint on it is not technology but sorting. Aluminium alloys are not interchangeable: a wrought alloy contaminated with a casting alloy's silicon can no longer be rolled, and iron picked up from steel attachments is impossible to remove and downgrades every subsequent melt permanently. So scrap is traded in defined grades that describe what it is and what it may contain, and those grade names are the terminology this part fixes. Without them a scrap contract is a guess. This document defines the terms for recycled aluminium - sorted scrap used for secondary aluminium and aluminium alloys, which may be contaminated or mixed with non-aluminium material - and applies to recovery and recycling in the smelting, wrought, cast alloy and aluminium powder industries.

This document defines recycled aluminium (aluminium scrap recovered after sorting, used for secondary aluminium and aluminium alloys, which may be contaminated or mixed with non-aluminium materials material) terms and definitions. This document is applicable to aluminum recovery and recycling in electrolytic aluminum industry, deformed aluminum and aluminum alloy industry, cast aluminum alloy industry, and aluminum powder industry.
