7 akatevedzana aluminium alloy ndeye Al-Zn-Mg-Cu, Iyo alloy yakashandiswa muindasitiri yekugadzira ndege kubva mukupera kwema1940. The7075 aluminium alloyine chimiro chakaomarara uye yakasimba corrosion resistance, iyo ndiyo yakanakisa yeaviation uye Marine plates.Ordinary corrosion resistance, good mechanical properties uye anode reaction.

Mbeu dzakatsetseka dzinoita zvirinani kuchera kwakadzika kuita uye inosimudzira kupfeka kuramba. Iyo yakanakisa simba realuminium alloy ndeye 7075 alloy, asi haigone kuve welded, uye kushorwa kwayo kwekuora kwakashata, mazhinji CNC ekucheka ekugadzira zvikamu anoshandisa 7075 alloy. Zinc ndicho chinhu chikuru chealloy mune ino nhevedzano, pamwe nediki magnesium alloy inogona kugonesa zvinhu kuti zvigadziriswe nekupisa, kusvika kune yakanyanya simba hunhu.

Iyi nhevedzano yezvigadzirwa zvinowanzowedzerwa kune shoma shoma yemhangura, chromium uye mamwe maalloys, uye pakati peiyo nhamba 7075 aruminiyamu alloy ndiyo inonyanya kunaka, simba repamusoro, rakakodzera ndege fremu uye yakakwirira simba accessories. stress corrosion cracking maitiro; yakavharwa aluminium kana kumwe kurapwa kwekudzivirira. Kuchembera kaviri kunogona kuvandudza kuramba kwealloy stress corrosion cracking. Iyo purasitiki mune yakavharwa uye yakangodzimwa mamiriro yakadzikira zvishoma pane yakafanana mamiriro e2A12. zvishoma nani pane 7A04, ndiro static kuneta. Gtch inonzwisa tsitsi, kushushikana kwekuora kuri nani pane 7A04. density i2.85 g/cm3.

7075 aluminium alloyine yakanakisa michina zvimiro, yakananga mashandiro mune zvinotevera zvinhu:

1. Kusimba kwepamusoro: Simba rekusimba re7075 aluminium alloy rinogona kusvika kupfuura 560MPa, iyo ndeyesimba rakasimba rezvinhu zvealuminium alloy, iyo iri 2-3 nguva yeimwe aluminium alloys pasi pemamiriro akafanana.

2. Kusimba kwakanaka: Chikamu che shrinkage rate uye elongation rate ye7075 aruminiyamu alloy yakakwira zvishoma, uye nzira yekuputsika ndiyo yakaoma kuputsika, iyo inonyanya kukodzera kugadzirisa nekugadzira.

3. Kushanda kwakanaka kuneta: 7075 Aluminium alloy inogona kuramba ichichengetedza maitiro ayo akanaka emagetsi pasi pekunetseka kwakanyanya uye kazhinji kudzorera mutoro, pasina oxidation, crack uye zvimwe zviitiko.

4. inoshanda zvakanyanya mukuchengetedza kupisa:7075 Aluminium alloyinogona kuramba ichichengetedza yakanaka yemagetsi zvivakwa munzvimbo yepamusoro yekupisa, inova rudzi rwemhando yepamusoro inodzivirira aluminium alloy.

5. Good corrosion resistance: 7075 Aluminium alloy ine good corrosion resistance uye inogona kushandiswa mukugadzirwa kwezvikamu nepamusoro-soro yekudzivirira zvinodiwa.

Chimiro:

1.O-state: (nyika yakawedzerwa)

Implementation nzira: Kupisa 7075 aruminiyamu alloy kusvika zvakakodzera tembiricha, kazhinji pa 350-400 madhigirii celsius, chengeta kwenguva uye zvino zvishoma nezvishoma kutonhorera kusvika mukamuri tembiricha, chinangwa: kubvisa mukati kushushikana uye kunatsiridza plasticity uye kuoma kwezvinhu.The yakanyanya tensile simba 7075 (7075-0 0 dzikamo, 000 psi 4 psi) haipfuure 2800000 psi (psi4) uye MPa. goho simba re140 MPa (21,000 psi). Kurebesa kwezvinhu (kutambanudza pamberi pekutadza kwekupedzisira) ndeye 9-10%.

2.T6 (kuchembera kurapwa):

Implementation nzira: yekutanga yakasimba mhinduro kurapwa ndiyo alloy kudziyisa kusvika 475-490 madhigirii celsius uye nokukurumidza kutonhora uye ipapo kuchembera kurapwa, kazhinji pa 120-150 madhigirii Celsius insulation kwemaawa akati wandei, chinangwa: kuvandudza simba uye kuoma kwezvinhu.The yekupedzisira tensile simba T6 tempering 7075 ndiyo 510,540,400 MPa00000000000 MPald (7075 MPald simba) yeinenge 430,480 MPa (63,00069,000 psi). Iine kukundikana kuwedzera mwero we5-11%.

3.T651 (kutambanudza + kuchembera kuomesa):

Implementation nzira: pahwaro hweT6 kuchembera kuoma, chimwe chikamu chekutambanudza kubvisa zvakasara kushushikana, chinangwa: kuchengetedza simba rakakwirira uye kuoma paunenge uchivandudza plastiki uye kuoma.Kunyanya kusimba kwesimba reT651 tempering 7075 ndeye 570 MPa (83,000 psi) uye goho reMP0000000000000000000 (p500). Iine kukundikana elongation rate ye3 - 9%. Aya hunhu anogona kushandurwa zvichienderana nechimiro chechinhu chakashandiswa. Mahwendefa akakora anogona kuratidza simba rakaderera uye kureba kupfuura nhamba dzakanyorwa pamusoro.

Kushandiswa kukuru kwe7075 aluminium alloy:

1.Aerospace field: 7075 aluminium alloy inoshandiswa zvakanyanya mumunda weaerospace nekuda kwesimba rayo guru uye maitiro asina kusimba. Inowanzoshandiswa mukugadzirwa kwezvivako zvendege, mapapiro, bulkheads uye zvimwe zvikamu zvakakosha, pamwe chete nezvimwe zvivako zvinoda simba rakakwirira uye kusagadzikana kwekuora.

2. indasitiri yemotokari: Iyo 7075 aluminium alloy inoitawo basa rakakosha mukugadzira mota. Inowanzo shandiswa muiyo braking system uye chassis zvikamu zvepamusoro-inoita mota uye mota dzemujaho, kuitira kuvandudza mashandiro emotokari uye kuderedza huremu.

3. midziyo yekurovedzera muviri: Nekuda kwesimba rayo rakakura uye huremu huremu, 7075 aruminiyamu alloy inowanzoshandiswa kugadzira midziyo yemitambo, senge tsvimbo dzekufamba, makirabhu egorofu, nezvimwe.

4. Kuvaka muchina: Mumunda wekugadzira michina, 7075 aruminiyamu alloy inoshandiswawo zvakanyanya mukugadzirwa kwezvikamu zvakanyatsonaka, molds nezvimwe zvakadaro. Pamusoro pezvo, 7075 aruminiyamu alloy inoshandiswa zvakanyanya mukufuridza epurasitiki (bhodhoro) mold, ultrasonic plastiki welding mold, shangu mold, bepa epurasitiki mold, furo rinogadzira mold, wax mold, modhi, fixture, mechanical equipment, mold processing nezvimwe minda. Iyo inoshandiswawo kugadzira yakakwirira-yekupedzisira aluminium alloy bhasikoro mafuremu.

Zvinofanira kucherechedzwa kuti kunyange7075 aluminium alloyine zvakawanda zvakanakira, zvichiri kudikanwa kuti utarise kushata kwayo welding kuita uye tsika yekushushikana kuora kwekuputika, saka iyo aluminium coating kana imwe yekudzivirira kurapwa inogona kudiwa mukushandiswa.

Kazhinji, iyo 7075 aruminiyamu alloy ine chinzvimbo chakakosha muminda yakawanda yemaindasitiri nekuda kwekuita kwayo kwakanaka uye kushandiswa kwakakura.
