AluminumPlate/Sheet is one of the most widely used categories in aluminum processing materials. It has diverse classification dimensions and is applied in multiple industries. The following provides a systematic overview from various perspectives to introduce the properties of aluminum plates.

1.Technical and Process Advantages

1) Mature smelting and casting rolling technologies: Our factory has developed standardized temperature control for different aluminum plate materials such as 1 series (pure aluminum), 3 series (aluminum-manganese alloy), and 5 series (aluminum-magnesium alloy). For example, the precise melting temperature control for pure aluminum is maintained within 660-700℃. The degassing and slag removal processes effectively reduce the defect rates of internal pores and inclusions in the ingots, and the mechanical properties of the finished aluminum plates (such as tensile strength and elongation) fluctuate within ±5% range, which is much better than the industry average of ±8%.

2) High-precision rolling and surface treatment processes: We are equipped with multiple upgraded four-roll reversible cold rolling machines that can precisely roll aluminum plates with thickness ranging from 0.1mm to 10mm. The thickness tolerance can reach as low as ±0.01mm, meeting the extremely high precision requirements of fields such as electronics and packaging. At the same time, we master a full range of surface treatment processes including anodizing, electro-etching coating, and film coating, which can be customized according to customer needs (such as mirror finish, matte finish, or brushed finish), and the adhesion and corrosion resistance of the coatings pass the salt spray test (neutral salt spray test ≥ 500 hours). The maturity of the process has been verified through long-term market validation.

3) Rapid response capability for customized processes: Our factory has established a "process parameter database". For special scenarios (such as 5 series aluminum plates for marine use with corrosion resistance, and 3 series lightweight aluminum plates for automobiles), we can quickly match exclusive production processes without the need for long-term trial production and debugging. The process confirmation cycle for customized orders is 30% shorter than the industry average.

2.Advantages in Quality Control Management

1) Selecting raw materials carefully: Only high-purity aluminum ingots that meet the standards of GB/T3190 (China) or ASTMB209 (USA) are purchased. The aluminum content must be ≥ 99.7%. Each batch of raw materials needs to be tested for composition using a spectrometer to prevent product performance issues caused by excessive impurities.

2) Real-time monitoring of the production process: Key processes (such as melting, rolling, and annealing) are equipped with online detection equipment - the melting process monitors composition and temperature in real time, the rolling process controls thickness using a laser thickness gauge, and the annealing process monitors the uniformity of furnace temperature using thermocouples. Data is recorded every 10 minutes to ensure traceability of the production process.

3) Full-item inspection of finished products: The finished aluminum plates need to undergo four-level inspections: appearance, size, performance, and weather resistance. The appearance is inspected using visual and light detection, without defects such as scratches or color differences; size is checked using micrometers and vernier calipers (sampling rate ≥ 5%); mechanical properties are tested using a universal material testing machine for tensile and yield strength; for outdoor-use plates, additional high and low temperature cycling tests (-40℃ to 80℃, 50 cycles) are conducted for weather resistance. Non-conforming products are 100% reworked, and the factory pass rate is stable at over 99.8%.
