40×40 aluminium t slot

Standard sizeCross-section size: 40mm × 40mmWall thickness: generally between 1.2mm – 3.0mm, common thickness is 1.5mm or 2.0mmSlot width (T-slot): 8mm or 10mm (depending on the specific model)Aperture (center hole): Φ12, used for strong anchor connectors (suitable for M14 bolts, can be transfered to M6, M8, M10 with reducer bolt)Effective length: 6000mm each bar (can be cut and customized according to needs) Structural features40×40 aluminium t slot usually adopt T-slot design, which is convenient for installing various connectors, such as angle code, nuts, bolts, etc.With high load-bearing capacity, it is suitable for structural frames, brackets and automation equipment, etc.Some models have internal reinforcement ribs to improve overall strength. Common aluminum alloy grades40×40 aluminum profiles usually use 6063-T5 or 6061-T6 aluminum alloys. These two materials have their own advantages in mechanical properties, corrosion resistance and machinability:MaterialFeatures6063-T5– Excellent corrosion resistance and surface treatment performance– Good extrusion performance, suitable for complex profiles– Moderate strength, suitable for most frame structures6061-T6– Higher strength for heavy-duty applications– Excellent mechanical properties and wear resistance– Suitable for applications requiring higher rigidity, such as industrial automation equipment Material propertiesParameter6063-T56061-T6density (g/cm³)2.72.7Tensile Strength (MPa)≥205≥290Yield Strength (MPa)≥170≥240Hardness (HB)7395Elongation (%)≥8≥10 The surface treatment of 40×40 aluminum profiles is mainly used to enhance corrosion resistance, wear resistance, and improve aesthetics. The following are common surface treatment processes(1) Anodizing· Features: The most common surface treatment method, enhancing corrosion resistance and aesthetics, and providing a hard surface.· Oxide film thickness: Generally between 8-15μm, industrial grade can reach more than 25μm.· Common colors: Silver (natural color), black, gold, gray, etc.(2) Electrophoresis Coating· Features: Add a uniform coating on the basis of anodizing to improve weather resistance and wear resistance.· Advantages: The surface is smoother and the color is uniform, suitable for occasions with high requirements for appearance.· Common colors: Silver, black, champagne.(3) Powder Coating· Features: The powder is evenly coated on the profile surface by using an electrostatic spraying process, and then cured at high temperature to form a wear-resistant layer.· Advantages: Rich colors, strong corrosion resistance, suitable for outdoor environments.· Common colors: black, white, gray, blue, etc.(4) Brushed· Features: Fine brushed texture is formed by mechanical grinding to enhance texture and aesthetics.· Applicable scenarios: High-end industrial design, electronic equipment housing, etc.(5) Polishing· Features: Make the profile surface reach a mirror gloss and improve the decorative effect.· Disadvantages: Easy to produce scratches, not suitable for high friction environments.   ParameterValueUnitDescriptionMoment of inertia (Ix, Iy)6.41 × 10⁴mm⁴Affects the bending stiffness.
