[China Aluminum Industry Network] 6063 Aluminum Alloy extrusion, online quenching and aging process technology conditions.
Control the temperature of the casting rod heating 440-480 °C; mold heating temperature 450-480 °C, the mold heating time is less than 5h; squeeze tube heating temperature 460-500 °C, extrusion speed: 12-18m / min; outlet temperature 510 -550°C; Cooling method is online air cooling or water mist cooling; Extrusion profile is quenched after on-line aging, control temperature is 200±5°C, holding time: 3h.
The combination of solution treatment and extrusion process of 6063 aluminum Alloy can avoid grain growth and improve the physical and mechanical properties of profile products.
Niobium is a shiny gray metal with paramagnetism and belongs to Group 5 on the periodic table. High Purity Niobium has high ductility, but hardens as the amount of impurities increases. Its outermost electron-layer arrangement is very different from other Group 5 elements. The same phenomenon occurs on the front and back ruthenium (44), rhodium (45) and palladium (46) elements.
