Furniture parts | Main applicable alloy grade | Core selection reason | |
Frame/support structure (e.g., columns, beams, table legs) | Balanced strength and ductility: With moderate strength, it can be strengthened through heat treatment (e.g., T5/T6 state), capable of withstanding high loads without significant deformation. Additionally, its excellent extrusion properties enable the production of complex cross-sectional shapes (such as hollow tubes with reinforcing ribs), making it an ideal choice as a "skeleton" material. | - Wall thickness requirements: For load-bearing components (e.g., table legs), a minimum thickness of 2.0mm is recommended; cabinet frames must have a nominal wall thickness of at least 1.0mm. | |
Cabinet/Panel (e.g. shelves, side panels, door panels) | 5052、5083 | Strength and Formability: The material exhibits moderate strength, making it particularly suitable for manufacturing large-area panels. Its excellent weldability and superior corrosion resistance ensure stable performance in humid environments such as kitchens and bathrooms, with minimal susceptibility to corrosion. | - Applicable Scene：It is especially suitable for outdoor furniture, bathroom cabinet, balcony cabinet and other places with high corrosion resistance requirements. |
Complex decorations/non-load-bearing elements (e.g., Roman columns, decorative moldings, handles) | 6063 | Excellent workability: The 6063 alloy boasts the best extrusion performance among all common grades, with high surface finish, making it ideal for crafting intricate and delicate decorative lines. Its superior surface treatment responsiveness enables flawless wood grain transfer and spray painting effects. | - Wall thickness requirements: Non-load-bearing decorative elements may be as thin as approximately 1.0mm. |
Texture of the cross-section: While it mimics wood grain, the cut or drilled areas reveal the underlying metallic color (silver-white or matte gray), which is the most direct way to tell the difference between genuine and fake.
Structural form: Most commonly adopt "hollow structure" or "honeycomb-filled structure". This is because pure aluminum is too soft and it must be alloyed and designed with specific cross-sectional shapes (such as reinforcing ribs) to ensure strength while reducing weight.
Surface coating: All wood grain and fabric patterns are not made of impregnated paper, but are transferred through high-temperature infiltration into the fluorocarbon coating on the surface, ensuring wear resistance and long-lasting color retention.
Chemical-free: The panel joints are not bonded with urea-formaldehyde resin and the edges are sealed without hot melt adhesive (or with minimal metal-specific adhesive), eliminating all sources of formaldehyde, benzene, and other TVOCs (Total Volatile Organic Compounds).
Thermal properties: High thermal conductivity means that if the ambient temperature is low, there will be a noticeable cool sensation upon touch; conversely, there will be no stuffy feeling.
Electromagnetic properties: It has a certain shielding effect on radio signals. This should be noted occasionally in cases of large-scale use of aluminum plates (such as fully aluminum-clad background walls), but it has little impact on individual furniture units.
Connection method: Unlike three-in-one fasteners, all-aluminum furniture typically employs welding, screw fastening or unique mortise-and-tenon joints.
Slot structure: Requires extremely high precision, typically machined by CNC (computer numerical control) machines, with tolerances controlled within millimeter-level accuracy.
Plate surface characteristics: Early spliced plates had obvious joints (reserved for thermal expansion and contraction prevention), while modern full-plate technology produces a smooth, seamless surface.
Ready-to-occupy: Traditional panel furniture requires ventilation and odor dissipation for over six months, whereas all-aluminum furniture, due to its base material containing no wood fibers or formaldehyde-based adhesives, enables same-day installation and occupancy. This provides the most attractive safety barrier for pregnant women, infants and individuals with respiratory sensitivities.
Water and oil resistance: Wood is sensitive to moisture and panels are vulnerable to dampness, whereas aluminum is an inert metal. Even if kitchen cabinets are frequently exposed to dishwashing water, soy sauce or vinegar, they will not swell, mold or rot as long as they are thoroughly wiped clean.
Termite-proof: Wood fibers serve as the primary food source for termites and insects, whereas aluminum alloy, being an inorganic material, remains completely unappealing to these pests, thereby eliminating the risk of insect damage at its source.
Unyielding to the sun: Balconies are often the 'testing ground' for furniture. Ultraviolet rays can cause wood to fade and leather to crack, yet fluorocarbon-treated aluminum alloy furniture remains pristine even after a decade of exposure to sunlight. Its flame-retardant properties also eliminate the need for worry about cigarette burn marks.
Structural stability: Solid wood may crack or deform due to temperature and humidity changes, while panels can warp from moisture absorption. Aluminum alloy, however, has an extremely low thermal expansion coefficient. In extreme environments ranging from-50°C to 50°C, its dimensions remain virtually unchanged, ensuring true crack-free and deformation-free performance.
Durability: The premium surface coating features high hardness and scratch resistance. A complete aluminum furniture set can theoretically last 30-50 years, far exceeding the typical replacement cycle of 5-10 years for conventional panel furniture.
The load-bearing capacity is strong: Because of the internal design of the aluminum profile reinforcement and the hollow structure has a certain elasticity, the layer of the aluminum furniture load-bearing capacity is often better than the same thickness of particle board, and it is not easy to appear the phenomenon of "collapsing waist".
Easy to clean: The surface is smooth and dense, with no adhesion of oil or dust. It can be vigorously wiped with a damp cloth or even a brush without concern for surface damage.
High residual value: When a set of furniture is used for decades and needs to be discarded, wooden furniture can only be treated as waste (even requiring paid disposal). In contrast, aluminum alloy is a recyclable metal. At market prices, not only is the disposal cost zero, but it can also generate a significant amount of scrap aluminum recycling fees, effectively serving as a form of value preservation.
