Aluminium Casting Heat Treatment
Aluminium Casting Heat Treatment
The heat treatment of aluminium castings entails the application of elevated temperatures to alter their physical characteristics, typically through a controlled thermal cycle—or a succession thereof. Depending on the specific alloy and the industry it is intended for, this process may be employed to either enhance hardness or increase ductility.
Beyond modifying hardness, aluminium heat treatment serves several critical functions: it can refine grain structure, homogenize alloy composition, and relieve internal stresses within the metal, thereby improving its mechanical integrity.
There is no universally standardised procedure for aluminium heat treatment. Instead, a tailored combination of techniques is employed to achieve the desired metallurgical properties. Commonly utilised methods include annealing, solution heat treatment, precipitation hardening, quenching, artificial ageing, and age hardening.
ALUMINIUM CASTING
HEAT TREATMENT FACILITIES
- Solutionising
- Precipitation
In T6 process, we maintain a temperature 525 c for 8hrs after reaching the set temperature .After completion of 8hrs, quenching takesplace within 20 secs.In precipitation ,we maintain the shell temperature 165 deg c for 8hrs.We achieve hardness of 80 to 120 max. and which compliance to AIAG- CQI -9.
Our furnaces have been specifically designed to provide uniform heat transfer to all areas of the castings. 9 Point Calibration is done as scheduled.
At M/s. Dhwani Engineering, we have the expertise to undertake Aluminium castings of complex components of diverse application in various industries. Some of the products made using casting process are Housings, Junction boxes, impellers, Valve bodies, Flanges, Manifolds, Actuator bodies, Compressor parts, Electrical fittings parts, Covers, etc.
