Kedu ?d? njirimara nke ?t?t? ?d? alloys nd? a na-ah?kar?? China aluminom extrusion ?l? ?r? mmep?ta ihe iji m?takwuo:

(1) 1035 alloy.

1035 alloy b? ulo oru d? ?cha aluminom na ihe na-erugh? 0,7% ad?gh?, n'etiti nke ígwè na s?l?k?n b? isi ad?gh?.Iron na s?l?k?n na ?f?d? nd? ?z? metal ad?gh? nwere ike ubé mma ike, ma budata belata plasticity na conductivity nke alloy.

Purel? ?r? d? ?cha nke aluminom nwere nkw?si ike d? elu n'?t?t? mgbasa ozi, nke d? elu kar?a ?la nd? ?z? nwere nnukwu ikike.Mmad? kw?siri ike nke aluminom b? n'ihi nguzobe nke mkpa, ihe nkiri oxide d? n'elu aluminom.

Obere ad?gh? ?cha na aluminom (?kachas? iron na s?l?k?n), nke ka elu ya na-eguzogide ns?. N'ezie, naan? magnesium na manganese anagh? belata mbibi nke aluminom.

A na-enye ngwaah?a nd? a gw?chara nke 1035 alloy n'okpuru mgbakwunye na ?k? ?k? ?k?. Otú ? d?, n'agbanyegh? ?n?d? nke ?k?n?, usoro nhazi ikpeaz? nke profa?l? a na-emep?ta b? ?gbat? agbat?, nke nwere ike ?gbat? na igwe na-agbat?. a na - emewanyewanye ihe ike site na mma, mana plasticity na - ebelata ngwa ngwa.

T?kwas? na nke ah?, nr?p?ta eletriki nke alloy na-ad?wanye mma n'oge nr?r? oyi. Ya mere, mgbe ihe ngosi profa?l? ch?r? siri ike, ? d? mkpa ?t?le mgbanwe ar?m?r? d? n'elu mgbe ? na-agbazi.

Mgbe okpom?k? na-abawanye, ike na plasticity nke 1035 alloy m?bara sharply.When okpom?k? d? n'okpuru efu, ike na plastic Njirimara nke alloy na-budata mma.

(2) 3 a21 alloy.

Alloy 3A21 bu ihe adighi nma na usoro ihe omuma nke AlMn nwere oke nguzo nke corrosion ma buru ihe dika nke 1035 alloy. k?ntakt? ?gbado ?k?.The corrosion eguzogide nke weld b? otu ihe ah? d? ka nke isi metal.The alloy nwere ezi deformation ar?m?r? na oyi na-ekpo ?k? na-ekwu, na okpom?k? nso nke thermal deformation b? nn?? obosara (320 ~ 470C). na-ewusi ike site na ?gw?gw? okpom?k? na profa?l? alloy na-eweta na ?n?d? annealed ma ? b? extruded.

Mmet?ta nke ?n?d? nr?r? na ?s? ?s? na nr?r? nr?r? nke alloy 3A21 d? obere kar?a nke ?l? ?r? aluminom d? ?cha.

(3) 6063 alloy.

Dika onye nnochi anya nke a1-mg-si alloy, alloy 6063 nwere ezigbo ihe omuma na ngosiputa, ma obu ihe achoro maka iwuli Windows na ibo uzo.Ejiri plastik di elu na nguzogide corrosion n'okpuru onodu okpomoku na oso oso nsogbu .No nchegbu corrosion tend.D.D ?gbado ?k?, na corrosion eguzogide anagh? n'ezie ibelata.

A na-eme ka Alloy 6063 d? ike n'oge ?gw?gw? ?k?. Isi ihe na-ewusi ike na alloy b? MgSi na AlSiFe. nkw?s? na ?ka nká. N'oge a, njik?ta elongation na-ebelata ntak?r? (site na 23% ~ 25% na 15% ~ 20%) .Mgbe ?ka nká na 160 ~ 170 ℃, alloy nwere ike inweta mmet?ta ike ka ukwuu. N'oge a, ike mgbat? ah? abawanyela na 269.5 ~ 235.2MPa.Had?gh?, na ?ka nká, ihe ngwongwo plastik belatara nke ukwuu (= 10% ~ 12%).

Oge agbata n’agbata quenching na ?ka nká nwere mmet?ta d? ?r?ba ama na ogo ike nke 6063 alloy (na ?ka nká). Site na mm?ba nke oge etiti site na 15min ruo 4h, ike mgbat? na ike ike na-ebelata na 29.4 ~ 39.2MPa.The thermal mkpuchi oge n'oge keakamere ?ka nká enwegh? mmet?ta d? mkpa na n'ibu Njirimara nke 6063 alloy ?kara r?chara ngwaah?a.

(4) 6 kedu a02 alloy.

Nk?t? 6A02 alloy (na-enwegh? njedebe nke ?la k?pa) b? nke a1-mg-si-cu usoro alloy.It nwere nnukwu ihe onwunwe plastik na ?n?d? okpom?k?-?s? ?s? nke nr?gide nr?gide na okpom?k? ?l?.

Na mmep?ta nke 6A02 alloy extruded ngwaah?a nke mechara, ? b? ezie na ?d?naya ya nke manganese pere mpe, mana mgbe ?gw?gw? ?k? ah? enwegh? ike idobe usoro ? b?la edeghar?r?, yab?, nwere ike meziwanye ar?m?r? ike d? ukwuu. wusiri ike n'oge ?gw?gw? ?k?, na isi ike ya b? Mg2Si na W (AlxMg5Si4Cu).

Enwere ike ?bawanye ike site na ?ka nká mgbe ? nw?s?r?, nke d? okpukpu ab?? d? ka nke d? n'okpuru mgbakwunye, yana ihe d? ka okpukpu ab?? kar?a nke ah? n'okpuru ?ka nká mgbe emechara ya. Otú ? d?, na ?ka nká, ihe onwunwe plastik belatara nke ukwuu (elongation ikwu agbada site na ihe d?ka 1/2, na mkpak? mmek?r?ta belata ihe kar?r? 2/3).

Ngwongwo 6A02 d? iche na 6063 alloy. Ngwunye 6063 nwere nguzogide nh?juanya d? elu na ?n?d? ?ka nká na ?n?d? ?ka nká, ebe nguzogide corrosion nke ngwongwo 6A02 na-ebelata n'?z? doro anya na ?ch?ch? corrosionine na-ap?ta.

N'ime usoro mmebi ah?, ka ?la k?pa d? na alloy na-abawanye, ike nke ike ?nw? na-abawanye. D?ka ?m?maat?, ? b?r? na ?d?naya nke ?la k?pa b? 0.26%, mgbe ?nwa isii nke ule (na-agbasa na 30% NaCl ngw?ta), ike mgbat? nke alloy na-ebelata site na 25%, ebe mgbakwunye ya na-ebelata site na 90% .Ya mere, iji melite nguzogide corrosion, ihe ?la k?pa d? na alloy na-ejikar? ach?kwa ihe na-erugh? 0.1%.

6A02 alloy nwere ike ?b? nt?p? welded, mp?ak?ta welded na argon arc welded.The ike nke welded nkwonkwo b? 60% ~ 70% nke nke matriks metal.After quenching na ?ka nká, ike nke welded nkwonkwo nwere ike iru 90% ~ 95% nke ah? nke matriks metal.

(5) alloy 5 a06.

Alloy 5A06 b? nke al-mg-mn usoro.? b? nnukwu plastik na ime ?l? na okpom?k? d? elu, na-eguzogide ?gw? na ?t?t? mgbasa ozi, g?nyere mmiri mmiri. Ezigbo nguzo na-emebi corrosion na weldability nke alloy na-eme ya n'?t?t? ebe Ejiri ya na ?l? ?r? na-ar? ?r? ?gb? mmiri.Egwuregwu nke alloy nwere nnukwu ike na ngwongwo plastik.N'oge okpom?k? ?l?, ike nke welded nkwonkwo nwere ike iru 90% ~ 95% nke nke matriks metal.

Ihe edere n'elu bu iwebata otutu ihe eji kpochapu alloys na ihe ha bu. A bu ndi omenala aluminom extrusion ?l? ?r?, nwere ike inye: square aluminom extrusion, gburugburu extrusion aluminom na ndi oru nhazi ndi ozo, nabata icho
