Aluminum alloy scrap ‌ refers to aluminum alloy materials that have been eliminated or replaced during use, mainly including new scrap aluminum and old scrap aluminum.

CLASSIFICATION AND SOURCE

New scrap aluminum ‌: mainly from scraps and waste products generated by aluminum processing enterprises and casting manufacturers in the production process. These scraps are usually recycled by the production enterprises themselves and smelted into the original grade alloy, or directly transported to the aluminum electrolysis plant for reuse ‌.

‌Old scrap aluminum ‌: including discarded packaging containers, equipment parts, old aluminum doors and windows, aluminum parts in scrapped cars and machinery, etc. These scraps are collected through social recycling channels for recycling.

RECYCLING AND RECYCLING

Pretreatment‌: includes sorting, cutting, magnetic separation, packaging and drying to remove explosives, iron parts and excess moisture‌.

‌Smelting‌: Melting, refining and alloy composition adjustment in a reverberatory furnace or electric furnace. Flux is added during the refining process to prevent oxidation, and stirring is used to promote the separation of inclusions and hydrogen.

‌Alloy composition adjustment‌: After smelting, necessary alloy elements are added as needed to ensure that the composition of the final product meets the standard.

SPECIFIC APPLICATION SCENARIOS

‌Automobile manufacturing‌: Aluminum alloy scrap can be used for body structural parts and components in automobile manufacturing, reducing vehicle weight and improving fuel efficiency‌.

‌Construction industry‌: In the construction industry, aluminum alloy scrap can be used to make building materials such as doors, windows, curtain walls, etc., which are lightweight and high-strength‌.

‌Packaging industry‌: Waste aluminum containers such as cans can be recycled and reused to reduce the demand for new aluminum materials‌.

‌Electronic products‌: In the manufacture of electronic products, aluminum alloy scrap can be used to make shells and internal structural parts to improve the durability and lightweight of products‌.
