The 6061 alu alloy plate differs from 5052 in chemical composition, state, and use.
1. Different chemicals
The 6061 alu alloy plate is an Al-Mg-Si alloy with medium strength, good plasticity, and excellent corrosion resistance. In particular, no tendency of stress corrosion cracking, its weldability is good, corrosion resistance and cold working performance are good,
is a wide range of use. It's a promising alloy. Can be anodized coloring, can also be painted enamel, suitable for building decorative materials. Contains a small amount of Cu and therefore has a strength higher than that of 6063 alu,
but the quenching sensitivity is also higher than the 6063 alloy alu plate. After extrusion, it can not be air quenched, so it needs solution treatment and quenching aging to obtain higher strength.
5052 alu plate pickling solution concentration and temperatures, such as increasing the acid temperature and concentration will enhance the acid activity and can increase pickling speed. But for sulfuric acid and hydrochloric acid, the extent of the effect is
Different. When the concentration of the acid solution is increased, the solubility of the iron salt decreases (the solubility of iron dichloride in hydrochloric acid is higher than that of iron(2+) sulfate (anhydrous) in sulfuric acid) . So, the newly formulated sulfuric acid dissolves
The concentration of the solution should not exceed 20%. At present, most 5052 alu plates of the sulfuric acid solution of the maximum starting concentration of 15%, with which it has been produced to the specified less concentration of acid and maximum iron content, and then made
Waste replacement. The Institute of Metallurgical Machinery Science of the former Soviet Union proposed that the concentration of sulfuric acid pickling solution for the new 5052 alu plate should be 180 ~ 200 g/L, when the content of iron salt reaches 220 ~ 260 g/l, it should be replaced.
2. Different states
The difference between the state T6 and T651 of the 6061 alu alloy plate is that under normal circumstances, the internal stress of the T6 will be relatively large and the T6 will deform when processed. The most suitable state for processing should be T651, which is stretched on the basis of the T6,
the main alloying elements for 6061 alu alloy are magnesium and silicon, and the Mg2Si phase is formed. If it contains a certain amount of manganese and chromium, the bad effect of iron can be neutralized; sometimes a small amount of copper or zinc is added,
in order to increase the strength of the alloy without reducing its corrosion resistance, there is a small amount of copper in the conductive material to offset the bad effect of titanium and iron on the conductivity, zirconium or titanium can refine the grain size and control the recrystallization structure
Lead and bismuth can be added to improve machinability. Mg2Si solid solution in the alu, so that the alloy has an artificial aging hardening function. The main alloying elements in the 6061 alu alloy are magnesium and silicon, which have medium strength and good properties
The corrosion resistance, weldability, and oxidation effect are good.
AL-Mn series AL-5052 alu plate is one of the most widely used anti-rust alu alloys. This alloy has high strength, especially anti-fatigue strength, high plasticity, and corrosion resistance, can not be strengthened by heat treatment and can be hardened in semi-cold working
When the plastic is good, cold hardening when the plastic is low, corrosion resistance, good weldability, poor cutting performance, can be polished.
3. Different uses
5052 alu plate typical uses: for manufacturing aircraft fuel tanks, fuel pipes, as well as transport vehicles, ships sheet metal parts, instrumentation, street lamp bracket, rivets, hardware, electrical housing, etc.
Typical uses of 6061 alu alloy: aircraft parts, camera parts, couplers, ship fittings and hardware, electronic fittings and joints, decorative or various hardware, hinge heads, magnetic heads, brake pistons, hydraulic pistons, electrical fittings, valves, and valve parts.
4.5052 alu panels differ from 6061 alu alloy panels in price. Conventional 6061 alu alloy panels cost more than 5052 alu panels.
