5052 h32 aluminum sheet is 5052 aluminum that is H32 quenched. In order to achieve this tempering, the metal is strain-hardened and then stabilized so that its strength reaches about a quarter of the strength of annealing (O) and full hard (H38). 5052 h32 aluminum alloy is a high-strength, non-heat-treatable metal material containing magnesium as its added character element. Aluminum 5052-h32 also contains small amounts of chromium, silicon, iron, copper, manganese and zinc to increase the strength of aluminum-based products. This corrosion-resistant product also has excellent weldability and cold workability, making it suitable for a variety of applications.
Usually, 5052 aluminum alloy is stronger than other popular alloys (such as 3003 aluminum);
Since its composition does not contain copper, it has higher corrosion resistance. Even in salt water; has the best welding performance among all aluminum materials;
5052 is the most suitable alloy for forming operations. Compared with the 1000 series and 3000 series, it has good machinability and higher strength;
High-quality anodized aluminum, for it has excellent surface treatment quality, and the anodized coating is bright and transparent;
The magnesium content is sufficient to cause a significant decrease in the melting point without brittleness;
Lightweight, semi-smooth surface, matt polishing effect.
H32 in 5052 h32 aluminum sheet means that the 5052 aluminum sheet has been strain hardened to 1/4 hard tempered and has thermal stability. When magnesium is used as the main alloying element or in combination with manganese, the result is a medium to high strength non-heat treatable aluminum alloy.
The alloy composition of 5052 aluminum sheet in different crossfire states is the same. The difference between H32 and H34 stems from the heat treatment process and ends with the mechanical properties.
1. The tensile strength is different. The tensile strength of H32 is 210-260; the tensile strength of H34 is 230-280. What is tensile strength? The maximum load-bearing capacity of a metal under static tension.
2. The non-proportional extension strength is different. The non-proportional extension strength specified by H32 is 130; the non-proportional extension strength specified by H34 is 150. The defined non-proportional elongation strength Rp is the stress when the non-proportional elongation is equal to the specified percentage of the extensometer gauge length, and Rp0.2 is the stress when the specified extensometer gauge length is 0.2%.
3. The bending radius is different. The bending radius of H32 is 1.5t; the bending radius of H34 is 2.0t. The bending radius is the radius of curvature. In layman's terms, a very small segment on the curve is replaced by a circular arc. The radius of this circle is the bending radius.
