Common defects of 6111 aluminum plate and advantages of Haomei

Generally speaking, the formability of 6111 aluminum plate is poor, because 6111 aluminum alloy has a large difference in plastic deformation ability from steel due to its face-centered cubic crystal structure, so other stamping forming processes cannot be directly applied. Moreover, the 6111 aluminum alloy for sale has a serious wrinkling tendency: compared with the steel plate, the window between the wrinkling and cracking of the aluminum alloy plate is narrower, and the wrinkling tendency is serious. At the same time, the springback of 6111 aluminum plates is large, and it is difficult to control the precision of parts. The elastic modulus of aluminum alloy plate is only one third of that of steel plate, and the parts are easier to spring back. The edge wrapping of the aluminum plate is poor, and it is easy to crack and produce "orange peel" defects. The oxide layer on the surface of the 6111 aluminum plate has strong viscosity, which affects the service life of the mold. The oxide layer on the surface of the aluminum alloy plate has a large friction with the surface of the mold during the sheet drawing process, and it is easy to peel off and stick to the surface of the mold, causing damage to the mold. After trimming, the aluminum plate has large burrs and serious debris accumulation, which affects the surface quality of the parts and increases the cost of mold maintenance. Therefore, Haomei focused on research and experiment on how to make 6111 aluminum plates to solve the above problems. In this way, we can provide customers with better and better quality products.

Compared with the existing traditional technology, the 6111 aluminum plate manufactured by Haomei has many beneficial effects. Let's see what it is! First of all, the aluminum alloys conventionally used for stamping are cold-rolled aluminum sheets, but Haomei adopts the 6111 aluminum sheet after solid solution to carry out the stamping forming process, which can greatly improve the formability of the aluminum alloy sheet and avoid the influence of age hardening on the formability of the aluminum sheet. Components that require high strength properties. As a result, the properties of the 6111 aluminum plates produced by Haomei reach the tensile strength rm≥330mpa, the yield strength rp0.2≥280mpa, and the elongation a50≥14%.

Haomei's excellent manufacturing methods enable us to obtain high-strength and low-cost stamped 6111 aluminum plate and automotive aluminum parts for sale, and can replace rolled aluminum sheets with extruded aluminum sheets. This has a positive impact on the supply of 6111 aluminum plates, and expands the application in auto body parts, and is of great significance for realizing the lightweight of automobiles.
