Product Description

4A11 and 4032 are Al-Si-Cu-Mg series Forged aluminium alloys. They are both forged and cast aluminium alloys. They can be strengthened by heat treatment. It has the advantages of small coefficient of thermal expansion and good wear resistance. It has good heat resistance, fatigue resistance and low temperature mechanical properties. It has good plasticity in hot state and good corrosion resistance.

4A11 and 4032 aluminium alloy forgings are mainly used to manufacture materials for piston and cylinder of steam engine, as well as complex forgings working below 200 C and bearing heavy loads.

Tensile Properties of 4A11 4032 Aluminum Alloy at Room Temperature and Low Temperature
Temper	Temperature/ºC	Tension strength Rm/MPa	Prescribed plastic elongation strength Rp0.2/MPa	Elongation A (%)
T62	-200	460	337	11
	-100	415	325	10
T62	-30	385	315	9
	25	360	290	2.5

For complex or heavy forgings, the water temperature during quenching can be increased to 65-80 ºC to avoid the deformation of forgings, but the mechanical properties will decrease.
Generally, the transfer speed during quenching should not exceed 10 s. For heavy forgings, the transfer speed should not exceed 15 s, so as to avoid affecting the mechanical properties and corrosion resistance of the alloy.
The two alloys have good plasticity in hot state. They are suitable for extrusion into bar and various interface profiles, and for making various forgings.
