Explore our primary structural plates, specialized coated coils, and engineered banding products designed for heavy industrial applications.
Positioned at the apex of China's non-ferrous metallurgical hub, delivering global structural connectors and precision metal components.
Founded in 2011 within the advanced manufacturing corridor of Dongguan, Guangdong, Dongguan Cellar Aluminum Co., Ltd. has evolved from a specialized alloy cutting workshop into a globally recognized benchmark manufacturer for engineered aluminium connectors, architectural structural components, and high-purity industrial sheet materials.
Operating as a premier Aluminium Plate Manufacturer | Aluminium Sheet & Industrial Metal Material Supplier, the company bridges the critical gap between raw melt refining and tight-tolerance end-user component manufacturing. Our state-of-the-art industrial park houses fully automated cold-rolling mills, 5-axis CNC machining centers, tension leveling lines, and environmentally isolated anodizing lines, enabling us to guarantee micro-structural uniformity and high dimensional repeatable precision across high-volume production batches.
Understanding mechanical properties, grain structures, and heat treatment tempers for optimal joint integrity.
In structural engineering, the design of Aluminium Connector Products requires a precise calibration between yield strength, elongation, fracture toughness, and stress-corrosion cracking (SCC) resistance. Unlike standard steel fasteners, aluminum connectors leverage unique intermetallic precipitates (such as Mg2Si in 6000-series or Al2MgCu in 7000-series alloys) formed during precipitation hardening (temper treatments such as T5, T6, and T651).
The operational lifespan of a structural joint depends fundamentally on matching the alloy substrate with the environmental and mechanical load profile. Below is an engineering selection breakdown based on metallurgical research and empirical testing protocols conducted at Dongguan Cellar Aluminum's testing facility.
| Alloy Series | Primary Alloying Element | Tensile Strength (MPa) | Yield Strength (MPa) | Corrosion Resistance | Primary Engineering Applications |
|---|---|---|---|---|---|
| 1000 Series (e.g., 1050, 1100) | Pure Aluminium (99.0%+) | 70 - 145 | 35 - 125 | Exceptional (Atmospheric/Chemical) | Electrical busbars, chemical shielding, heat exchangers, decorative sheets. |
| 3000 Series (e.g., 3003, 3105) | Manganese (Mn) | 110 - 210 | 60 - 180 | Very High | Roofing sheets, PPGI/PPGL substrates, automotive heat shields, pressure vessels. |
| 5000 Series (e.g., 5052, 5083) | Magnesium (Mg) | 190 - 350 | 90 - 240 | Superior (Marine/Saltwater) | Marine connectors, structural ship hulls, transport tanks, industrial banding. |
| 6000 Series (e.g., 6061-T6, 6063) | Magnesium & Silicon (Mg2Si) | 150 - 310 | 110 - 275 | High (Good Anodizing Quality) | Structural framing connectors, solar panel mounting, architectural facades, CNC brackets. |
| 7000 Series (e.g., 7075-T6, 7A52) | Zinc (Zn) & Copper (Cu) | 480 - 580 | 410 - 505 | Moderate (Requires Coating) | Aerospace structural lugs, defense armaments, ultra-high stress mechanical linkages. |
Solution heat-treated and artificially aged to achieve maximum dispersion strengthening. Provides maximum yield strength for heavy structural brackets and load-bearing connectors.
Electrochemical process converting the metal surface into a durable, corrosion-resistant anodic oxide finish. Crucial for exterior facade connectors and marine environments.
When aluminium connects to steel, galvanic corrosion can occur. Our engineering team supplies specialized isolation shims, coated zinc-aluminum fasteners, and dielectric barriers.
Why leading global EPC contractors, automotive Tier-1 suppliers, and distributors source directly from Dongguan Cellar Aluminum.
Direct integration with primary liquid aluminium smelters in China minimizes remelt energy costs. This cost advantage is directly transferred to global buyers via lower mill gate pricing per ton.
Our in-house tool and die shop produces custom connector extrusion dies in 7–10 business days, drastically shortening new product introduction (NPI) cycles for OEM project managers.
We utilize London Metal Exchange (LME) and Shanghai Futures Exchange (SHFE) hedging strategies to offer international buyers fixed-price forward contracts, insulating projects from metal volatility.
From green energy transition infrastructure to high-speed railway structural joints.
Utility-scale solar farms demand lightweight, high-strength structural connectors capable of enduring 25+ years of exposure to wind shear and UV radiation. Our anodized 6005A-T6 and 6063-T6 aluminum connectors provide high corrosion resistance without requiring routine maintenance coating.
The rapid shift toward automotive lightweighting places high demand on structural crash-worthy aluminum components. Cellar Aluminum supplies high-ductility 5052-H32 and crash-rated 6061-T6 machined connectors for EV battery pack structural enclosures.
1000 and 6000 series aluminum busbar connectors engineered for ultra-high electrical conductivity and minimal contact resistance. Our specialized silver-plated or electro-tin finished connectors prevent oxidation in outdoor transformer yards.
Saltwater environments degrade conventional metals. Our marine-grade 5083-H116 and 7A52 aluminum sheets and custom structural connectors resist intergranular corrosion and stress-corrosion cracking in marine environments.
