2024 t851 aluminum block bar

Dec 24, 2022

The 2024 t851 aluminum block bar belongs to the Al-Cu-Mg series of aluminum alloys. It is a kind of high-strength hard aluminum, which is mainly used to make various high-load parts and components.
specification:
Aluminum type: hard alloy
Standard: GB, GJB, GBN, ASTM, EN, etc.
Delivery status: T851
Processing: customized according to customer requirements

The chemical composition of 2024 t851 aluminum block bar:
Copper Cu: 3.8%-4.9%
Manganese: 0.30%-1.0%
Magnesium Mg: 1.2%-1.8%
Chromium Cr: 0.10%
Zinc: 0.25%
Aluminum Al: margin

Features of 2024 t851 aluminum block bar:
This is a kind of high-strength duralumin, which can be strengthened by heat treatment. It has medium plasticity in quenched and freshly quenched conditions. It has good spot welding and severe intergranular cracks when gas welding is used. The alloy can be hardened after quenching and cold work. The cutting performance is still good, and the machinability is low after elimination: the corrosion resistance is not high, and anodizing and painting methods are often used or the surface is coated with aluminum to improve its corrosion resistance.

The purpose of 2024 t851 aluminum block bar:
Mainly used to make various high-load parts and components (but not stamping forgings) such as aircraft skeleton parts, skins, bulkheads, ribs, spars, bolts and other working parts below 150°C.
