5052 black anodized aluminum plate for sign making/laser engraving

What is 5052 aluminum plate?

5052 aluminum plate is an AL-Mg alloy aluminum plate, in which magnesium is the main alloying element, and it is also a widely used rust-proof aluminum. This alloy has obvious advantages, with high strength, fatigue resistance, strong plasticity, and high corrosion resistance. 5052 aluminum plate contains a variety of elements, such as aluminum, magnesium manganese, chromium, beryllium, titanium, etc. Among them, the role of chromium is similar to that of manganese, both of which have the ability to improve the resistance to stress corrosion cracking and the strength of the base metal and weld, and also reduce the tendency of welding cracks.

Aluminum alloy oxidation is just an electrolytic process that can deposit a chemically stable oxide layer on the aluminum surface. Thus, a new oxide film is obtained, which will be stronger and thicker than the original one, and some problems such as paint peeling can be avoided. The oxide film is generally 5-25 microns, and generally 5 microns is decorative oxidation, which can improve the strength of 5052 aluminum plate. The anodized aluminum plate is also suitable for extrusion, casting, rolling, forging, bending and other manufacturing processes as the original one.

5052 black anodized aluminum plate has good deep processing performance such as milling, cutting, and engraving. It is suitable for the production of door panels, engraving panels, machined parts, etc. It is corrosion-resistant and has a long service life.

Performance comparison of 5052 aluminum plate in different tempers

✅ 1. Forming performance

* 5052 aluminum plate alloy has good hot process plasticity. During the process, its forging and die forging temperature is about 420 ~ 475℃. This temperature range can be 80% hot deformation.

* 5052 aluminum plate alloy cold stamping performance is related to the alloy state. The cold stamping performance of annealed state is good, and the H32 and H34 tempers are reduced. The cold stamping performance is not good in the H36/H38 state.

✅ 2. Welding performance

* 5052 aluminum alloy has good resistance welding, gas welding, arc welding, spot welding and seam welding performance. It has a tendency of crystallization cracks during argon arc welding, while brazing performance is good and soldering performance is poor, so pay attention to the welding type to avoid failing to meet the required standards.

* 5052 aluminum plate weld has high strength and plasticity. The weld strength can reach about 90%~95% of the base metal strength, but the weld air tightness is not high. It is generally recommended to use 5A03 alloy as solder because it can improve air tightness and eliminate crack tendency.

* 5052 aluminum plate has poor machinability in the annealing state, but it will improve in the cold hardening state, so be sure to pay attention to the oxidation changes in different tempers.
