2A14 Aircraft Aerospace Grade Aluminum Plate Sheet

2A14 Aircraft aerospace grade aluminum plate sheet is a metal material used in applications requiring high strength and hardness (including high temperature). The 2A14 series aluminum plate is characterized by high hardness, among which the copper content is the highest, about 3-5%. With the development of my country's aerospace industry, the aluminum plate production technology of the 2A14 series will be further improved. Aircraft heavy-duty, forgings, thick plates and extruded materials, wheels and structural elements, multi-stage rocket first-stage fuel tanks and spacecraft parts, truck frames and suspension system parts.

It's close to 2014. The main varieties are bars, profiles, forgings and plates, etc. It is suitable for high load parts with thick section. The welding performance of the alloy is good, and it does not show brittleness at the cold temperature. It can be used to make the welding parts under the cold working condition.
