Production process of Chalco aluminum alloy 7050 (UNS A97050) bar

Aluminum ingot preparation: the production of 7050 aluminum alloy usually starts from aluminum ingots, which are processed by melting and casting, and generally have high purity and good crystallization properties.

Preheating and rolling: aluminum ingots are heat-treated in a preheating furnace, and then rolled into aluminum rods of required diameters through a rolling mill. During the rolling process, parameters such as rolling temperature and rolling speed need to be controlled to ensure the quality of the obtained aluminum rod.

Non-heat treatment: the aluminum rod is rolled through multiple passes and subjected to work hardening treatment to improve the strength, hardness and wear resistance of the aluminum rod.

Heat treatment: aluminum rods are heated under specific temperature and time conditions, so that the aluminum alloy material can obtain ideal properties and microstructure. Common heat treatment methods include aging treatment and solution treatment.

Cutting and processing: according to customer requirements, aluminum rods are cut and processed into parts of required length and shape.

Inspection: conduct various inspections on the manufactured 7050 aluminum rods, including tests on dimensions, mechanical properties, chemical composition, surface quality, etc., to ensure that they meet customer requirements and corresponding quality standards.

Packaging and transportation: pack the qualified 7050 aluminum rods, mark and record them, and then send them to customers.
