Haomei manufacturing method of 6111 aluminum alloy plate for sale

In order to meet the development requirements of automobile lightweight, more and more lightweight materials are applied to automobiles, and 6111 aluminum alloy plate for sale has the characteristics of low density, light weight, easy processing and forming, corrosion resistance, age hardening, etc. The first choice for automobile manufacturers to replace steel plates to reduce vehicle weight. Due to the different materials of 6111 aluminum alloy plates and steel plate, there is a big difference in mechanical properties between the aluminum alloy plate and the steel plate for the body, so the numerical simulation theory and process design experience or standard of traditional steel plate stamping cannot be applied to the aluminum alloy body parts. The stamping process design is carried out, and due to the aging hardening phenomenon of the aluminum plate, its material parameters will change with the increase of storage time, resulting in unstable parts quality after stamping. Haomei uses a unique preparation method of 6111 aluminum alloy plate stamping parts, especially involving extrusion stamping forming process, this technology can help us avoid common defects.

In order to overcome some common technical defects, Haomei can provide unique 6111 aluminum alloy plate stamping and forming technology. This process includes the following steps.

First we need to cast and extrude aluminum sheets. The cast aluminum alloy includes the following components by mass percentage: 0.762%si, 0.127%fe, 0.095%cu, 0.582%mg, 0.464%mn, 0.013%zn, 0.021%ti, 0.081%cr, and the balance is al At the same time, the aluminum alloy aluminum rod extrusion process parameters are: the aluminum rod temperature is 410 ~ 430 ° C, the extrusion speed is 2.8 ~ 3.2 mm/s (preferably 3.0 mm / s), and the outlet temperature is 500 ~ 520 ° C ( Preferably 520°C), water cooling.

Secondly, we should stamp the 6111 aluminum alloy plates after solution treatment. When the aluminum plate is subjected to solution treatment, the parameters of the solution process are as follows: the solution temperature is 490±5°C, and the solution time is 30 minutes. However, after the solid solution of the 6111 aluminum alloy plates is completed, we must complete the stamping process within 4 hours (<4h). Because when the time exceeds 4 hours, the stamped aluminum plate will have cracks or orange peel.

Next, we will strengthen the stamped aluminum plate by artificial aging heat treatment. The 6111 aluminum alloy plate is strengthened by artificial aging heat treatment, the aging process is 180±5℃, and the temperature is kept for 6 hours.
