Note: longitudinal mechanical properties of aluminum rodss at room temperature
1) Rapid annealing: heating temperature 350-410 with the effective thickness of the material, the holding time is between 30-120 min; air or water cooling.
2) High temperature annealing: heating temperature 350-500, finished prodsuct thickness & ge; 6 mm, holding time 10-30 min, < 6 mm, heat penetration until; air cold.
3) low temperature annealing: heating temperature of 150~250 degrees; holding time of 2 ~ 3H; air or water cooling.
