how to custom aluminum sheet fabrication for specific projects
Define project requirements
First of all, you need to define the project requirements, which should mainly contain:
- end use: what products custom aluminum sheet metal will be used for. Will it be a housing for machinery and equipment, a curtain wall for a building, a heat sink for electronics, or a controller panel? Different uses dictate different performance priorities.
- Environment: Will custom aluminum sheet metal be exposed to indoor, outdoor, humid, chemically corrosive, or high or low temperature environments? This will affect the choice of alloy and finish.
- Load Requirements: How much static or dynamic load does the aluminum sheet metal need to withstand? Does it need to withstand stress or bending?
- Aesthetic Requirements: What are the specific requirements for surface appearance, such as gloss, texture, and color?
- Codes and Standards: Does the project need to meet specific industry standards, such as aerospace, medical device, or food grade.
The design concept is then translated into detailed technical engineering drawings using CAD software. At Supro, we can help you through the CAD drawing design process.
Selection of suitable aluminum plate
Aluminum sheet is not a single material, different aluminum alloys have different functional properties due to different compositions and heat treatment states. Therefore, before starting custom aluminum sheet fabrication, you need to select the most suitable aluminum sheet for your project. Common choices include:
1xxx Series: 1050, 1050A, 1060, 1100. Industrial pure aluminum with good corrosion resistance, formability, electrical and thermal conductivity, and surface finish, but lower strength. Suitable for chemical containers, aluminum plates, decorations, radiators, fused wires, conductive materials, etc.
2xxx Series: 2014, 2017, 2024. Higher copper content, poorer corrosion resistance, but high strength, can be used as structural materials, such as airplanes, gears, axles and so on.
3xxx Series: 3003, 3004, 3005, 3105. 3003 is the most commonly used general-purpose alloy, with higher strength than the 1xxx series, and has has good molding and welding properties. It is suitable for kitchenware, tanks and sheet metal processing.
5xxx series: 5005, 5052, 5754, 5083. 5052 has medium strength, good corrosion resistance, weldability and formability, especially suitable for resistance to seawater and marine atmospheric corrosion, and high fatigue strength. Widely used in ships, vehicles, aircraft fuel tanks and other fields.
6xxx series: 6061, 6082, 6063. 6061 is the most classic heat treatment strengthened alloy with high strength, good toughness, excellent welding performance and high durability value after T6 treatment. It is widely used in aerospace, automotive frames, and high-precision parts. 6082 is a medium-strength extrusion alloy with strengths between 6061 and 6063. It has good extrudability, pressability and hardenability, and can be used as a large sheet material with complex shapes, good corrosion resistance and weldability. 6063 has a lower strength than 6061, good extrudability, and can be used as a profile with complex cross-sectional shapes, good corrosion resistance and surface finish, and is suitable for use in construction, guardrails, vehicles, furniture, home appliances, and decorative products.
7xxx series: 7075. Its strength is extremely high, but the corrosion resistance is poor, mainly used for high stress structural parts, such as aircraft skeletons, molds.
Consider the thickness of aluminum sheet metal
The thickness of custom aluminum sheet metal will affect the rigidity, strength and weight of the parts, and the safety standards are different in different industries:
Structural Strength: Load bearing or stressed parts require thicker sheet metal to prevent deformation.
Weight constraints: For mobile equipment or transportation, light weight is very important and thinner plates should be selected wherever possible to ensure strength.
Cost factors: The thicker the sheet, the higher the material cost, and the difficulty and cost of processing may also increase.
Forming process: Some deep-drawing forming processes require a specific thickness range to ensure molding quality.
Consider the thickness of aluminum sheet metal
Depending on your project and design requirements, it is important to choose the right custom aluminum sheet fabrication technique.
Laser cutting: high precision and flexibility, suitable for rapid prototyping and mass production of complex shapes and medium-thickness sheets.
CNC stamping: suitable for high-volume, thin sheet processing with standard hole patterns, high efficiency, but higher mold costs.
Waterjet Cutting: Cold cutting, no heat-affected zone, suitable for heat-sensitive materials or the need to avoid work-hardening occasions, can cut any thickness.
plasma cutting: suitable for thick plate fast rough machining, lower cost, but the cutting accuracy and kerf smoothness is not as good as laser cutting and waterjet cutting.
Bending: custom aluminum sheet fabrication when using a bending machine to bend the aluminum sheet into the required angle, which is the most commonly used method to manufacture boxes, brackets and other structures.
Roll bending / rolled plate: aluminum sheet rolled into a curved or cylindrical shape, such as pipes, silos.
Stamping/deep-drawn: using dies to deform aluminum plates under pressure, used to manufacture deep-cavity parts with complex shapes, such as pots and pans and shells.
Spinning: Suitable for the production of axisymmetric round parts, e.g. lampshades, rocket head cones.
Welding: TIG and MIG welding are often used in custom aluminum sheet fabrication to provide strong connections.
Riveting: This is a type of mechanical connection that is suitable for joining different materials without thermal deformation.
Threaded connections: screws and bolts are used for easy disassembly and maintenance.
Bonding: Using industrial adhesives, the stress is evenly distributed, enabling sealing and insulation.

Surface treatment
Surface treatment is a very critical process in custom aluminum sheet fabrication, its purpose is to enhance the surface performance of aluminum sheet, to meet the needs of the product for aesthetic and environmental durability.
Mechanical treatment
It is mainly through the physical way to change the surface texture or finish of aluminum, mainly drawing, polishing, sandblasting and other methods.
Brushed: using abrasive materials to form a straight line or swirl-like texture on the surface of the aluminum plate. The appearance is fashionable, wear-resistant and can hide fine scratches, widely used in electronic products, home appliances and elevator interiors.
Sandblasting: Uses a high-speed sand stream to impact the surface, creating a uniform, fine matte texture. Provides better coating adhesion.
Polishing: Mechanically or electrolytically polishing the surface to a mirror-like finish. Mainly used for high-end decorative parts and reflectors.
Chemical treatment
Chemical oxidation: generates a thin and dense oxide film on the surface with good adsorption, often used as pretreatment for painting, which can significantly improve paint adhesion and provide basic corrosion resistance.
Electroplating: Depositing a layer of other metals (such as nickel, chromium, copper) on the surface of aluminum to improve its conductivity, weldability or to obtain a special decorative appearance.
Anodizing
Anodic oxidation is to generate a hard, stable film of aluminum oxide on the surface of aluminum.
This is the most commonly used and effective surface treatment method, which can greatly improve the surface hardness, wear resistance and corrosion resistance, and can be dyed into a variety of colors.
The vast majority of architectural aluminum, consumer electronics, automotive components, and aerospace parts are subject to anodizing.
Spraying
Powder Coating (Powder Coating): Dry powder is electrostatically adsorbed onto the surface of the material and then cured at high temperatures. It is a thicker, more robust coating with a very wide selection of colors and textures, and has excellent weather resistance for outdoor construction and home applications.
Spray Painting: Spray painting using traditional liquid paints. It can achieve some special artistic effects and a very smooth surface with flexible color mixing.
