● Litšobotsi le boholo ba ts'ebeliso:
Motsoako oa aluminium 1200 ke aluminium e hloekileng ea indasteri e nang le polasetiki e phahameng, khanyetso ea kutu, motlakase le conductivity ea mocheso, empa
Matla a fokolang, heat treatment can not strengthen, ho se sebetse hantle; ho cheseletsa khase, tjheseletsa ea athomo ea haedrojene le ho tjheseletsa ho kopana, not easy
Brazing; ho bonolo ho mamella ts'ebetso e fapaneng ea khatello le katoloso, kobeha.
●Heat treatment specifications:
1) Ho koenya ka potlako: mocheso oa mocheso ke 350-410°C; ho itšetlehile ka botenya bo sebetsang ba thepa, the holding time is
Between 30 le 120 metsotso; ho phodisa moya kapa metsi.
2) Mocheso o phahameng oa annealing: mocheso o futhumatsang 350 ~ 500℃; ha botenya ba sehlahisoa se felileng ke ≥6mm, the holding time is 10~
30min, <6mm, until it is heated through; phodiso ya moya.
3) Low-temperature annealing: mocheso oa mocheso oa 150-250 ° C; holding time 2-3 hours; ho phodisa moya kapa metsi.
