6061 T651 Aluminum Sheet

 

6061 Aluminum Sheet is an aluminum alloy plate with Si and Mg as the main elements. The content of Mg and Si is 0.8-1.2% and 0.4-0.8%. 6061 aluminum alloy is a very important one in the 6000 series aluminum alloys.

Uses and advantages of thin 6061 aluminum sheet:

White surface/bright surface. No milling required. Cost-saving. Widely used in 3C fields such as mobile phone card slots, buttons, computer brackets, computer shells, trolley boxes, aluminum furniture, door panels/door handles. 6061 aluminum alloy sheets can be used for 5G mobile phones

Uses and advantages of 6061 medium-thick aluminum plate:

The internal stress is relieved, and the cutting will not deform. It is widely used in underwear molds, shoe molds, precision machining. Passenger car decorative panels/checkered plates, car chassis protection parts, car four doors, two covers, car wheels, car seats.

6061 Aluminum Sheet Heating Treatment

Rapid annealing

Heating temperature 350 ~ 410 °C, holding time 30 ~ 120 min depending on material effective thickness. Air or water cooling.

High temperature annealing

The heating temperature is 350 ~ 500 °C, the holding time is 10 ~ 30min when the thickness of the finished product is ≥6mm. Stops after heat penetration when the thickness of the finished product is less than 6mm. Air Cooling.

Low temperature annealing

The heating temperature is 150 ~ 250 °C and the holding time is 2 ~ 3h. Air or water cooling. Homogenization annealing 570 degrees Celsius, seven hours of insulation. Air cooling
