GNEE 5083 H22 Aluminium Alloy
5083-H22 yog ib qho txhuas-magnesium alloy los ntawm 5xxx series ntawm uas tsis yog- tshav kub- kho tau aluminium alloys. Nws yog ib hom kab mob - hardened thiab ib nrab annealed variant ntawm 5083, featuring siab magnesium ntsiab lus thiab zoo heev corrosion kuj. Lub H22 temper qhia tias cov alloy tau raug strain{12}}hardened rau lub quarter-hard mob thiab ib nrab annealed los txo cov kev ntxhov siab sab hauv thaum tuav ib feem ntawm lub zog tau txais thaum lub zog hardening.
Yam ntxwv ntawm 5083 H22 Aluminium
Cov tawv nqaij tawv tawv:Mechanical deformation yog siv los txhim kho lub zog thiab hardness.
Ib nrab Annealing:Kev kho cua sov txo cov kev ntxhov siab sab hauv, ua tiav qhov sib npaug ntawm lub zog thiab ductility. H22 temper muab kwv yees li 25% ntawm tag nrho cov zog, ntawm annealed (O) thiab tag nrho hardened (H28) xeev.
Corrosion Resistance:Kev tiv thaiv zoo heev rau cov dej hiav txwv thiab kev lag luam chemical corrosion, zoo tagnrho rau marine thiab tshuaj siv.
Weldability:Zoo weldability nrog TIG / MIG txheej txheem; haum rau marine thiab structural fabrication.
Ua haujlwm tau:Txhawb kev tsim cov txheej txheem xws li stamping, khoov, thiab ncab.
