2024 and 2A12are the high strength, fatigue-resistant aluminum alloys,are the heat-
treatable grade of aluminum,and have good machinability, good corrosion in non-industrial atmospheres;The temper T4 is Solid solution treatment plus natural aging.Therefore,2024 2A12 T4 Aluminium alloy extruded square bars with high strength,can be used for weighing apparatus.
Chalco Aluminum Aluminium alloy extruded square bars specification:
The square bars thickness:5-85mm
The square bars width:5-85mm
The square bars length:according to customer’s requirements.
Main Function: weighing apparatus
