Diamond aluminium checker plate is an ideal material for toolboxes. Its unique pattern design and aluminum alloy properties meet the requirements of lightweight, corrosion resistance, and structural strength. The surface of diamond aluminium checker plate for tool box resembles a pointer, with raised projections typically 0.1-1.2mm high. This increases the coefficient of friction and provides anti-slip properties (anti-slip ratings up to R10-R12 per EN 13845). Furthermore, the patterned structure increases the aluminium checker plate's rigidity by 20%, resulting in superior bending resistance compared to ordinary flat aluminum plates.

Alloys of Diamond Aluminium Checker Plate For Tool Box:

- 5052 Aluminum Alloy:

An aluminum-magnesium alloy with strong corrosion resistance (especially seawater resistance) and excellent weldability, suitable for outdoor or humid environments (such as truck toolboxes). Its yield strength is approximately 193 MPa, making it lightweight (density 2.71 g/cm³), but its strength is lower than 6061 aluminum.

- 6061 Aluminum Alloy:

An aluminum-magnesium-silicon alloy with a tensile strength of 310 MPa and high hardness, suitable for heavy-duty toolboxes that need to bear heavy loads. It can be strengthened through T6 heat treatment, but be aware of the risk of thermal cracking after welding. AC tungsten inert gas (TIG) welding and matching wire (such as ER5356) are recommended.

- 3003 Aluminum Alloy:

An aluminum-manganese alloy with excellent rust resistance and low cost, suitable for economical toolboxes that do not require high strength.

Performance Parameters of Diamond Aluminium Checker Plate For Tool Box:

- Thickness Range:

1.5-3mm is commonly used, balancing lightweight and deformation resistance. Custom thicknesses of 0.8-25mm are available upon request.

- Surface Treatment:

Anodizing: Produces a dense oxide film (thickness ≥ 10μm) with salt spray corrosion resistance exceeding 3000 hours (ASTM B117), wear resistance, and a durable color (such as silver-white or black).

Powder coating: Available in a variety of colors and at a lower cost, but less scratch-resistant than anodizing, making it suitable for indoor or short-term use.

- Mechanical Properties:

5052-H32 has a tensile strength of approximately 228 MPa and an elongation of ≥12%; 6061-T6 has a tensile strength of ≥310 MPa and an elongation of ≥10%, meeting the impact resistance requirements of toolboxes.

Processing of Aluminium Checker Plate For Tool Box:

- Embossed:

A patterned roller pattern is embossed into the aluminum sheet surface using a rolling mill. The rolling pressure must be controlled (usually 500-800 MPa) to ensure pattern clarity and consistent depth.

- Welding:

AC TIG welding is preferred. Before welding, the surface oxide film should be cleaned with a stainless steel wire brush and preheated to 100-200°C (for thicknesses >5 mm). Welds should be pickled or cleaned with chromic acid solution to prevent corrosion.

- Cutting and Bending:

Laser cutting accuracy can reach ±0.1 mm. A bending radius of ≥1.5 times the sheet thickness is recommended to avoid cracking. For complex structures, CNC molding technology can be used.

Application Scenarios of Aluminium Checker Plate Tool Box:

- Transportation:

Truck and pickup tool boxes (e.g., Amazon's best-selling product uses diamond aluminum plate, customizable with private labeling).

- Industrial:

Equipment repair tool boxes and power engineering portable cases require a combination of the corrosion resistance of 5052 aluminum and the high strength of 6061 aluminum.

- Outdoor:

For yacht or marine tool boxes, 5052 aluminum alloy with anodizing is recommended to resist seawater corrosion.

Thanks to its high-quality alloy, processing technology, and structural design, diamond aluminium checker plate significantly enhances the durability and practicality of tool boxes while also meeting lightweight and aesthetic requirements.
