7xxx Series Aluminiyam Plates: Properties, Applications & Machining Guide

I-7xxx iipleyiti ze-aluminium ze-7xxx ziyaziwa ngamandla abo obunzima bobunzima obukhethekileyo, okwenza kube yinto ekhethekileyo kumashishini asebenza kakhulu. Kwesi sikhokelo, siza kuchitha yonke into oyifunayo malunga nosapho lwe-alloy, ukusuka ekubunjweni, kumatshini kunye nokusetyenziswa.

Yintoni 7xxx Series Aluminium?

II-7xxx ye-aluminiyam i-alloy serieskwintsapho ye-zinc-magnesium alloy (njenge-7075, 7050, 7475), eyenzelwe ngokukodwa izinto eziphathekayo ezinamandla aphezulu. Iimpawu eziphambili ziquka:

Izithako eziphambili: i-zinc (5-8%) + i-magnesium + ubhedu.

Unyango loBubushushu: Uninzi lwamabanga anonyango lobushushu (i-T6/T7 temper) ukwenzela ukuqina okuphuculweyo.

Amandla: Amandla okuqina ukuya kuthi ga kwi-570 MPa (ngaphezu kweentsimbi ezininzi).

Qaphela: Ukumelana nokubola kungaphantsi kancinane kune-6 uluhlu lwe-aluminium alloy (ukhuseleko lokugquma).

I-7075 yeyona nto ixhaphakileyo ye-7xxx ye-aluminium alloy, ezona mpawu ziphambili zinamandla aphezulu, ukumelana nokudinwa okugqwesileyo, ukusetyenziswa okuqhelekileyo sisakhelo senqwelomoya, izixhobo zomkhosi, njl.

Isizathu sokukhetha aI-7-series aluminiyam i-alloy plate

I-Ultra-High Strength: Ifanelekile kumacandelo athwele umthwalo.

Ubunzima: 1/3 ubuninzi bentsimbi.

Ukumelana noBubushushu: Igcina iipropati kumaqondo obushushu aphezulu.

Ubuchule: Ukufezekisa ukunyamezela okuqinileyo ngezixhobo ezifanelekileyo.

7 uluhlu lwezakhono ze-aluminium alloy processing plate

Ukukhethwa kwesixhobo

Izixhobo zokusika: Izixhobo zeCarbide okanye i-polycrystalline diamond (PCD).

Isixhobo seJiyometri: Ii-engile zehariki eziphezulu (12°–15°) ukunciphisa ubushushu.

Ukuthambisa: Sebenzisa isisipholisi senkungu ukunciphisa ukukhuhlana.

Isantya kunye neNcombolo zokutyisa

Milling: 800–1,200 SFM (umphezulu iinyawo ngomzuzu).

Ukugrumba: 150-300 RPM nge-peck drilling ukucima iichips.

Kuphephe Ukuncokola: Khusela iipleyiti ezinezixhobo zokufunxa.

Ukhathalelo lwasemva koMatshini

Ukunciphisa Uxinzelelo: Amalungu e-Aneal ukuthintela ukulwa.

I-Anodizing: Faka i-Type II okanye i-III anodizing yokukhusela umhlwa.

Imingeni eqhelekileyo kunye nezisombululo

Uxinzelelo lwe-Corrosion Cracking:

Unobangela: Uxinzelelo olushiyekileyo + iindawo ezifumileyo.

Lungisa: Sebenzisa umsindo we-T73, sebenzisa iingubo ezikhuselayo.

Ukutya ngexesha lokukhulelwa:

Isizathu: Umxholo ophezulu we-zinc.

Lungisa: Sebenzisa iimpompo ezigqunyiweyo; thambisa ngeoli enzima.

Izicelo eziphezulu ze7xxx Aluminiyam Amacwecwe

I-Aerospace: Izixhobo zamaphiko, izixhobo zokumisa.

Ukhuseleko: Amacandelo emoto exhobileyo.

Imidlalo: Iifreyimu zebhayisekile, izixhobo zokukhwela.

Iimoto: Amalungu enjini yoxinzelelo oluphezulu.
