Raws li ib tug ua lag luam ntawm txhuas cov khoom thiab precision machining cov kev pab cuam, peb paub txog qhov tseem ceeb ntawm kev xaiv cov khoom zoo rau kev thov. Ntawm cov kev ua haujlwm siab aluminium alloys,2019 aluminium phaj standstawm raws li qhov kev xaiv hwm zoo tsim rau qhov chaw huab cua. Kab lus no delves rau hauv metallurgical muaj pes tsawg leeg, txhua yam yam ntxwv, thiab ntau yam kev siv ntawm 2019 txhuas phaj, muab kev nkag siab los pab engineers thiab procurement specialists txiav txim siab.
Tshuaj muaj pes tsawg leeg: Kev Tshawb Fawb Tom Qab 2019 Txhuas
2019 txhuas yog cov khoom siv hlau uas muaj nyob rau hauv 2000 series (aluminium-tooj liab tsev neeg). Nws muaj pes tsawg leeg yog precisely calibrated kom ua tiav qhov zoo sib npaug ntawm lub zog, machinability, thiab thermal stability. Cov ntsiab lus tseem ceeb ntawm alloying muaj xws li:
Copper (Cu): 5.2% ~ 6.8% Txhim khu lub zog thiab nag lossis daus teb.
Magnesium (Mg): 0.25% ~ 0.7% Txhim kho qhov muaj peev xwm-hardening thiab thermal stability.
Manganese (Mn): 0.4% ~ 1.0% Tswj cov qauv nplej thiab recrystallization tus cwj pwm.
Hlau (Fe): ≤0.30% Tswj raws li impurity kom tswj ductility.
Silicon (icon (Si): ≤0.25% Tswj kom tsis txhob muaj kev cuam tshuam ntawm intermetallic theem.
Zirconium (Zr) thiab titanium (Ti): Cov nyiaj tau los rau cov nplej ua kom zoo dua qub thiab txhim kho cov yam ntxwv ua haujlwm kub.
Cov hlau feem ntau yog muab rau hauv T3, T6, lossis T8 tempers, qhia txog kev kho cua sov, quenching, thiab kev laus dag kom ua kom cov khoom siv dag zog zoo tshaj plaws.
Mechanical thiab Physical Properties: A High-Performance Profile
2019 txhuas phaj nthuav tawm qhov tshwj xeeb lub zog-rau-qhov hnyav piv, ua tau zoo dua ntau cov qauv alloys hauv kev nruj thiab kev puas tsuaj. Tej yam khoom siv (rau T851 temper) muaj xws li:
Qhov kawg Tensile Strength (UTS): ≥62 ksi (427MPa)
Tensile Yield Strength (TYS): ≥42 ksi (290MPa)
Elongation ntawm Break: ≥10% (hauv 2 ntiv tes)
Shear zog: ∼34 ksi (234 MPa)
Fatigue Strength: Zoo heev nyob rau hauv cyclical loading tej yam kev mob.
Nws cov cwj pwm ntawm lub cev txuas ntxiv qhia txog nws qhov tsim nyog rau kev tsim kho qib siab:
Ceev: 0.101 lb/in³ (2.80 g/cm³)
Melting Range: 935 ℃ ~ 1180 ℃ (502 ℃ ~ 638 ℃ )
Thermal conductivity: 121 W/m·K
Hluav taws xob conductivity: ∼34% IACS
Qhov tseem ceeb, 2019 ua kom pom kev ua haujlwm zoo, ntsuas ntawm 80% txheeb ze rau tus qauv siv rau 2011-T3 alloy. Nws kuj tseem khaws qhov ruaj khov ntawm qhov ntev thoob plaws qhov kub thiab txias, tiv thaiv creep deformation nyob rau hauv kev txhawb nqa thermo-mechanical stresses.
Daim ntawv thov: 2019 aluminium phaj excellence teb
Ua tsaug rau nws qhov kev ua tau zoo profile,2019 aluminium phaj tau teev tsegnyob rau hauv ntau yam kev lag luam siab:
1. Aerospace & Defense: Siv nyob rau hauv tis tav, fuselage thav duab, thiab tsaws iav Cheebtsam vim nws lub siab tawg toughness thiab tsis kam mus tawg propagation.
2. Automotive Racing: Zoo tagnrho rau kev sib txuas ntawm kev ncua, chassis reinforcements, thiab cav mounts qhov twg qhov hnyav txo thiab kev co damping tseem ceeb heev.
3. Cov Tsheb Tub Rog: Siv rau hauv cov qauv tsheb armored thiab cov tshuab txuas txuas uas yuav tsum tau muaj kev ncaj ncees thiab kev poob siab.
4. Precision Tooling: Haum rau jigs, fixtures, thiab pwm puag yuav tsum tau ntev geometrical raug.
5. Thermal Management Systems: Nws balanced thermal expansion coefficient suits heat sinks thiab exchanger plates in avionics cooling units.
