Dab tsi yog 6061 thiab 7075 Aluminium Alloys?

6061 Aluminium Alloy

6061 belongs rau lub6xxx aluminium series, feem ntau alloyed nrog:

Magnesium (0.8-1.2%)

Silicon (0.4-0.8%)

Qhov kev sib xyaw ua ke no muab kev tiv thaiv corrosion zoo, lub zog nruab nrab, zoo weldability, thiab muaj zog formability. Vim tias nws cov khoom sib npaug, 6061 feem ntau muab faib ua astructural aluminium alloythiab yog siv dav hauv kev siv engineering.

7075 Aluminium Alloy

7075 yog ib feem ntawm lub7xxx aluminium series, alloyed feem ntau nrog:

Zinc (5.1-6.1%)- lub hauv paus ntxiv dag zog

Tooj liab (1.2-2.0%)

Magnesium (2.1-2.9%)

Cov txheej txheem no tsim ib qho ntawm covmuaj zog tshaj kev lag luam muaj aluminium alloys, nrog zoo heev mechanical thiab qaug zog zog. Cov ntsiab lus zinc siab yog qhov tseem ceeb tom qab nws lub zog zoo dua.

Kev kub ntxhov

Ob lub alloys feem ntau muab nkag rau hauvT6 zog(kev daws cov cua sov-kho thiab cov hnub nyoog artificially). Rau cov khoom siv phaj,t651 uakuj yog siv dav, qhia txog kev ntxhov siab ntxiv los ntawm kev ncab tom qab kev kho cua sov.

Raws li cov cai ntawm aluminium alloy designation:

6 xxxxxxxxxalloys yog raws li magnesium thiab silicon

7 xxxxxxxxxalloys feem ntau yog zinc-raws li

Kev sib piv - 6061 vs 7075 Aluminium

1. Lub zog

7075 txhuas muaj zog ntau dua li 6061. Cov txiaj ntsig zoo qhia:

6061-T6 tensile zog nyob ib ncig ntawm 45 ksi (310 MPa)

7075-T6 tensile zog mus txog 83 ksi (572 MPa)

Lub zog tawm los ua raws li qhov sib xws, ua rau 7075 qhov kev xaiv zoo tshaj plaws rau kev thauj khoom -cov kabmob thiab kev nyab xeeb- cov khoom tseem ceeb.

2. Hardness

7075 nthuav tawm ntau dua hardness (kwv yees li 150 HB) piv rau 6061 (kwv yees 95 HB), uas ua rau muaj kev hnav zoo dua thiab ua haujlwm ntev.

3. Machineability

Ob qho tib si alloys tshuab zoo, tab sis nrog qhov sib txawv:

6061 yog yooj yim dua ntawm cov cuab yeej thiab dav siv rau kev machining

7075 ua kom huv si chips thiab superior nto tiav, tab sis cov cuab yeej hnav yog siab dua

4. Weldability

6061 yog qhov zoo heev uas siv cov txheej txheem TIG lossis MIG

7075 feem ntau suav hais tias tsis yog -weldable vim kub tawg thiab poob lub zog loj

5. Corrosion Resistance

6061 muab kev tiv thaiv corrosion zoo dua qub, tshwj xeeb tshaj yog nyob rau hauv huab cua lossis dej hiav txwv ib puag ncig . 7075 yog qhov ua rau muaj kev ntxhov siab ntau dua thiab feem ntau yuav tsum muaj cov txheej txheem anodizing lossis tiv thaiv txheej.

6. Formability

6061 yog ntau formable thiab haum rau khoov thiab shaping . 7075 yuav tsum tau loj khoov radii thiab nruj txheej txheem tswj kom tsis txhob tawg.

7. Kev qaug zog

7075 muab kev tiv thaiv kev qaug zog zoo dua, ua rau nws zoo tagnrho rau kev thauj khoom cyclic thiab aerospace qauv.

8. Thermal conductivity

6061 muaj cov cua kub zoo dua, uas ua rau nws haum rau cov dab dej kub thiab cov khoom siv thermal.
