Abstract
This research aims to determine the effect of variations in cooling media (water, ice water and SAE 140 oil) on artificial aging processes on OEM wheels hardness (Al-Si) values.Manufacture of specimens from OEM wheels material. The process of making specimens uses the casting method sand casting. The test specimen is processed with the initial step of solution heat treatment temperature 500°C lasting time 5 minutes. Then quenching with a variety of water cooling media, ice water and SAE 140 oil. After quenching, artificial aging heat treatment is carried out at a temperature of 180°C lasting time of 4 hours. Results of hardness testing after artificial aging process against raw material after remelting increased in water cooling media from 52.61 BHN to 60.06 BHN, ice water media from 52.61 BHN to 60.06 BHN and SAE oil media 140 from 52.61 BHN to 55.25 BHN. The highest percentage increase occurred in water cooling media and ice water by 14.16%. Key words: artificial aging , hardness, cooling media, heat treatment, OEM wheels.
