Aluminum alloys are not interchangeable. A score that performs flawlessly in an aircraft wing may fail in a leatherneck hull, and a mollify optimized for physical phenomenon conductivity may be entirely wrong for a machined biology part. For engineers and procural teams, the key to a undefeated project is sympathy how debase interpersonal chemistry and mollify handling shape real-world public presentation and then sourcing that stuff from a provider who can deliver it with proved, trackable quality.
This steer examines four widely used aluminum alloys 7075 T73, 2024 T351, 3103, and 6101 and explains what each one does best. It also outlines what to look for in an atomic number 13 alloy supplier and how a trusty Al manufacturer China like Linsy Aluminum supports buyers across aerospace, leatherneck, physical phenomenon, and superior general technology sectors.

7075 T73: High Strength with Corrosion Resistance
The 7xxx serial publication sits at the top of the aluminum effectiveness pecking order, and 7075 T73 aluminium properties shine a carefully engineered trade-off. Built around zinc, magnesium, and copper, 7075 achieves strength levels that rival nerve at rough one-third the slant. The T73 season is an overaged that deliberately gives up about 12 15 of peak strength in for dramatically improved try-corrosion crack(SCC) resistance.
A elaborated 7075 T73 guide explains that the overaging work coarsens grain-boundary precipitates, reducing the electrochemical force for intergranular . The result is a stuff with a salt-spray life rough two to three multiplication thirster than T6, fracture temper of about 28 33 MPa m, and superior damage permissiveness.
Typical 7075 T73 aluminum properties include:
-
Ultimate stress effectiveness: 505 MPa
-
Yield potency: 435 MPa(still roughly 2.4 that of 6061-T6)
-
Excellent SCC and exfoliation resistance
-
Not suggested for spinal fusion welding
This mollify is the standard for aerospace structures in corrosive or cyclic service wing skins, fuselage frames, landing place gear components as well as devil dog and sea ironware where chloride exposure would a T6 part. For machined thick scale, the stress-relieved T7351 version adds a stretch out step for dimensional stability. Read more at https://premiumalu.com/ultimate-guide-to-7075-t73-aluminum-properties/.
2024 T351: Fatigue Resistance and Machining Stability
The 2024 T351 properties visibility makes this alloy a of airframe construction. As a copper-based 2000-series debase, 2024 delivers succumb effectiveness militant with mild steel at one-third the angle. The T351 temper adds a indispensable stress-relief step: after solution heat treatment and extinction, the material is flexible 1 3 to equalize residual stresses before cancel aging.
According to the 2024 T351 Al steer from Linsy, this stretching is what separates T351 from T3. A T351 plate corset flat during deep-pocket machining, while an unstretched T3 plate often warps as intramural stresses redistribute. Key 2024 T351 properties admit:
-
Ultimate stress potency: 470 MPa
-
Yield potency: 325 MPa
-
Excellent fatigue life in tension-dominated cycles
-
Not fusion-weldable(friction stir welding is an alternative)
This season is specified for wing lower skins, fuselage bulkheads, motorsport temporary removal components, and preciseness tooling. When selecting a 2024 T351 atomic number 13 supplier, that the mill has consummated the full natural ripening and provides nail MTC support.

3103 Aluminum Alloy: The General-Purpose Workhorse
For European-market projects, the 3103 aluminium debase(EN AW-AlMn1) is the standard Al-Mn mark, functionally equivalent weight to American 3003. As a non-heat-treatable alloy, 3103 gains its potency entirely through cold workings, which makes mollify survival the primary feather prize for reconciliation strength and formability.
A honest 3103 aluminium alloy supplier should offer the full season straddle O for deep drawing, H14 and H16 for roofing and facing, H18 for uttermost harshness. The 3103 aluminium debase is wide used in corrugated roofing, heat exchangers, chemical substance , kitchen utensils, and superior general tack-metal manufacture. Its key characteristics let in:
-
Excellent underground in atmospherical and fresh-water environments
-
Outstanding formability in O temper
-
Good caloric conductivity( 160 W m K)
-
Full EN 485 and EN 573-3 compliance
The tighter specify(0.10 max versus 3003’s 0.05 0.20) gives 3103 marginally better public presentation in certain -prone environments. Visit site https://premiumalu.com/product/6101-aluminum-alloy/.
What to Look for in a Chinese Aluminum Supplier
Choosing the right aluminium provider China goes beyond terms comparison. Consider these factors:
-
Certifications: ISO 9001, ISO 14001, and ISO 45001 exhibit a to timbre, , and refuge.
-
Documentation: Every shipment should include a Mill Test Certificate(MTC) per EN 10204 Type 3.1, with chemical substance and physics results trackable to the heat total.
-
Temper truth: Verify that the delivered season matches stipulation especially vital for Marine and aerospace grades.
-
Processing capacity: A good supplier offers cutting, machining, and rise up finish to tighten your ply complexity.
-
Lead multiplication and MOQs: Flexible lower limit order quantities and 10 60 day lead multiplication are standard for proved exporters.

Frequently Asked Questions
Q1: Why take 7075 T73 over 7075 T6?
T73 is overaged to deliver fantabulous try-corrosion cracking resistance, while T6 offers peak potency but only tame SCC underground. Choose T73 for , leatherneck, or long-service applications; take T6 for dry, limited environments where uttermost potency is necessary.
Q2: What is the main advantage of 2024 T351?
The T351 temper includes a try-relief stretching step that minimizes internal balance stresses. This makes thick plates dimensionally stable during machining, reducing warping and scrap in aerospace and preciseness components.
Q3: Is 3103 atomic number 13 the same as 3003?
Functionally, yes. Both are Al-Mn alloys with nearly superposable physical science properties. 3103 has a tighter limit of 0.10 max, while 3003 allows 0.05 0.20 Cu. They are interchangeable in most applications.
Q4: What is 6101 aluminum used for?
6101 is primarily used for physical phenomenon bus bars, conductors, and world power-distribution components. It offers a poise of physical science potency and high electrical conductivity, and is commons in switchgear and rail adhesive friction systems.
Q5: How do I verify Al tone from a Chinese supplier?
Request a Mill Test Certificate(MTC) per EN 10204 Type 3.1 confirming chemical substance composition and physical science properties. Reputable suppliers like Linsy also provide SGS test reports on quest and hold ISO 9001 certification.
