Aluminum Plate

5754 Aluminium sheet

5754 aluminium alloy is a typical Al-Mg alloy, which has the characteristics of medium strength, good corrosion resistance, weldability and easy processing and forming. Overseas, 5754 aluminium alloy sheets with different heat treatment status are the main materials used in automobile manufacturing (car doors, moulds, seals) and canning industry.

1 ) Chemical composition:

Si: 0.40;

CU: 0.10;

Mg: 2.6-3.6;

Zinc: 0.2;

Mn: 0.50;

Cr: 0.30;

Fe: 0.40;

Ti: 0.05;

Al: Allowance.

2 ) Heat treatment process:

1、Homogenization annealing: heating 440 C; holding 12-14 h; air cooling.

2、Rapid annealing: heating 350-410 C; holding time 30-120 min; air or water cooling.

3、High temperature annealing: heating 350-420 C; when the thickness of finished product is more than 6 mm or less than 6 mm, the holding time is 2-10 minutes or 10-30 minutes; air cooling.

4、Low-temperature annealing: heating 250-300 or 150-180 degrees; holding time 1-2 hours, air-cooled.

3) Application:

5754 aluminium sheet is widely used in welding structures, tanks, pressure vessels, ship structures and offshore facilities, transport tanks and tanks, as well as in occasions requiring excellent processing performance, excellent corrosion resistance, high fatigue strength, high weldability and medium static strength.
