●Characteristics and scope of application:

Aluminiumlegering 1200 is industrial pure aluminum with high plasticity, weerstand teen korrosie, elektriese geleidingsvermoë en termiese geleiding, maar
Low strength, heat treatment can not strengthen, swak verwerkbaarheid; gassweiswerk, hydrogen atom welding and contact welding, not easy
Brazing; maklik om verskeie drukverwerking en verlenging te weerstaan, buig.

●Heat treatment specifications:

1) Vinnige uitgloeiing: heating temperature is 350-410°C; afhangende van die effektiewe dikte van die materiaal, die houtyd is
Between 30 en 120 minute; lug- of waterverkoeling.
2) Hoë temperatuur uitgloeiing: verwarming temperatuur 350 ~ 500 ℃; wanneer die dikte van die voltooide produk ≥6mm is, the holding time is 10～
30min, <6mm, until it is heated through; lugverkoeling.
3) Low-temperature annealing: heating temperature 150-250°C; holding time 2-3 ure; lug- of waterverkoeling.
