Explore our precision-engineered structural solutions manufactured to sustain heavy structural load-bearing parameters.
Established in 2015 and located in Foshan City, Guangdong, LvXing Intelligent Equipment Co., Ltd. boasts a highly skilled R&D team with extensive engineering experience. We leverage exceptional technical expertise to effectively transform our customers' most complex ideas into functional reality, consistently meeting precise dimensional and metallurgical requirements.
We utilize premium Fenglu aluminum, offering a diverse and high-grade range of profiles for flexible, high-demand applications. Our extrusion capacity is anchored by state-of-the-art extrusion lines, ranging from 800T to 20,000T. This allows us to work with a broad spectrum of alloy series including 1xxx, 2xxx, 3xxx, 5xxx, 6xxx, and 7xxx. We can produce complex shaped products with section dimensions up to 1.2 meters in width and 28 meters in length.
Our dedication to quality is evident at every stage of the manufacturing process, spanning rigorous quality control, thorough protective packaging, and efficient international shipping procedures. This commitment has earned us recognition as a national excellent and honest enterprise, coupled with quality system certification in accordance with GB/T19001-2016/ISO9001:2015 standards.
We deploy advanced metallurgy, robust extrusion capacities, and custom engineering to deliver high-integrity aluminum extrusions.
We have successfully obtained the prestigious "Special Aluminium Materials for Aerospace" Certificate. This qualification establishes our capability to manufacture profiles capable of undergoing extreme stress, structural fatigue resistance, and thermal shifts typical of high-altitude flight vehicles and launch systems.
Through our long-term strategic partnership, we utilize premium Fenglu aluminum profiles. Our extrusion systems produce alloys across 1xxx to 7xxx series. We easily fabricate large structural members with cross-sectional widths reaching 1.2 meters and continuous lengths up to 28 meters.
Our engineering and metallurgy divisions maintain over 15 years of practical manufacturing experience. We evaluate customer concepts, isolate engineering constraints early, perform structural simulations, and deliver custom profiles that meet the most rigorous application requirements.
The 7000 series aluminum family, classified as an Al-Zn-Mg-Cu (Aluminum-Zinc-Magnesium-Copper) heat-treatable alloy, represents the peak of structural load-bearing performance in modern extrusion engineering. Zinc (ranging from 5% to 8%) serves as the primary alloying element, yielding exceptional precipitation hardening responses when paired with magnesium.
Copper additions are strategically introduced (often between 1% and 2%) to optimize stress corrosion cracking (SCC) resistance and enhance high-temperature performance metrics. Manganese, chromium, and zirconium are added as grain structure controllers, preventing recrystallization during heat treatment phases to maintain a fine-grained, robust micro-structure.
The structural properties of the 7000 series are highly dependent on the chosen temper. At Lvxing, we supply 7000 series profiles in several specialized temper conditions:
| Alloy Grade | Primary Additives | Tensile Strength (MPa) | Yield Strength (MPa) | Key Applications |
|---|---|---|---|---|
| 7075 | Zn, Mg, Cu, Cr | 570 (T6) | 500 (T6) | Aerospace Spars, Military, High-Stress Parts |
| 7050 | Zn, Mg, Cu, Zr | 515 (T7451) | 455 (T7451) | Thick Fuselage Plates, Marine structural frames |
| 7020 | Zn, Mg, Mn, Zr | 350 (T6) | 290 (T6) | High-Speed Rail, Armored Vehicle structures |
| 7005 | Zn, Mg, Mn, Zr | 345 (T5) | 290 (T5) | Welded structures, Marine helideck supports |
Note: Mechanical properties listed represent typical values. Custom tempers can be customized to meet specific engineering performance constraints.
As critical weight-saving components with high structural demands, 7000 series aluminum profiles are integrated across aerospace, rail, and marine operations.
In aerospace sectors, weight reduction directly translates to increased payload and fuel efficiency. Utilizing 7075-T6 structural shapes enables defense and aircraft manufacturers to replace heavy steel components. Applications include wing spars, fuselage stringers, bulkheads, and control surface tracks.
Oceanic environments demand corrosion mitigation and structural integrity. Lvxing designs specialized aluminum marine components, integrating perimeter safety nets (electric and manual), shipboard landing zones, and structural support frames. Our T73 heat-treated profiles prevent seawater-induced degradation.
High-speed commuter rail assemblies experience continuous dynamic loading and vibration. Utilizing 7020 and 7005 series profiles allows train manufacturers to assemble high-strength carbody frameworks, underframe bolsters, and cross-beams that balance weldability with impact absorption.
Our manufacturing capabilities in Foshan City, Guangdong, integrate automation and precision extrusion technology. By operating extrusion presses from 800T up to a massive 20,000T capacity, we maintain consistent control over the microstructural development of our profiles.
By sourcing raw billets from Fenglu Aluminum, we guarantee metallurgical purity, avoiding inclusions and compositional drifts that compromise structural performance.
Our manufacturing workflow relies on digital integration:
Lvxing employs a zero-defect quality policy. Each manufacturing batch undergoes testing procedures to verify compliance with international and national standards, including GB/T19001-2016 and ISO9001:2015:
Understand the primary cost components and pricing models associated with sourcing custom 7000 series aluminum profiles.
The foundational cost is tied directly to the London Metal Exchange (LME) or the Shanghai Metals Market (SMM) aluminum ingot indices. This base cost fluctuates based on global macroeconomic factors, energy tariffs, and raw material availability.
Intricate, hollow, or extra-wide profiles (up to 1.2 meters) require specialized die geometries. Custom extrusion dies represent an initial tooling cost, which is often amortized or waived for large-volume procurement runs.
Specific tempers like T73 or T76 involve multi-stage artificial aging processes that add processing time and cost. Furthermore, post-extrusion CNC milling, surface anodizing, and custom cutting to precise lengths add fabrication value.
To obtain an accurate quote, procurement officers should supply engineering drawings (DWG/IGS/STEP formats), alloy specification (e.g., 7075-T6), and yearly volumetric demands.
| Procurement Phase | Required Details | Cost Type | Standard Timeline |
|---|---|---|---|
| 1. Technical Review & Tooling Quote | 2D/3D Drawings, structural application, load requirements. | Die Tooling Fee (One-Time) | 3 to 7 Days |
| 2. Prototype Extrusion & Sample Testing | Sample production, dimensional checks, hardness testing. | Sample Cost (Refundable) | 10 to 15 Days |
| 3. Batch Production & Tempering | Mass extrusion, solution heat treating, aging to spec. | LME Ingot Price + Processing Fee | 20 to 30 Days |
| 4. Surface Finishing & CNC Machining | Anodizing, drilling, tapping, cut-to-length tasks. | Fabrication Add-on Fee | Variable based on complexity |
