Brushing treatment is done after stamping, and can be made into several types according to decorative needs, such as straight lines, irregular lines, threads, ripples, and spiral lines. Straight wire drawing refers to the process of machining straight lines on the surface of 5052 aluminum plate using mechanical friction. It has a dual function of brushing scratches on the surface of 5052 aluminum plate and decorating the surface of 5052 aluminum plate. There are two types of straight wire drawing: continuous and intermittent. Continuous silk patterns can be obtained by using a cleaning cloth or stainless steel brush to continuously horizontally and linearly rub the surface of 5052 aluminum plate (such as manually grinding or using a planer to clamp a steel wire brush on the 5052 aluminum plate under the condition of existing devices). Changing the diameter of the steel wire of the stainless steel brush can obtain different thicknesses of patterns.

断续丝纹一般在刷光机或擦纹机上加工制得。制取原理：采用两组同向旋转的差动轮，上组为快速旋转的磨辊，下组为慢速转动的胶辊，铝或铝合金板从两组辊。

Intermittent silk patterns are generally processed on a brushing or wiping machine. Production principle: Two sets of differential wheels rotating in the same direction are used. The upper group is a fast rotating grinding roller, and the lower group is a slow rotating rubber roller. Aluminum or aluminum alloy plates are divided into two sets of rollers.

（1）加工性好：阳级氧化铝板装饰性强，硬度适中，可轻易折弯成型，进行连续性高速冲压，方便直接加工成产品，无需再进行复杂的表面处理，大大减短产品生产周期和降低产品生产成本。

(1) Good processability: The positive grade aluminum oxide plate has strong decorative properties, moderate hardness, and can be easily bent into shape for continuous high-speed stamping, making it easy to directly process into products without the need for complex surface treatment, greatly reducing the product production cycle and reducing production costs.

（2）耐候性好：标准厚度氧化膜（3μm）的阳较氧化铝板室内使用长期不变色，不腐蚀，不氧化，不生锈。加厚氧化膜（10μm）的阳较氧化铝板可使用于室外，可长期暴露于太阳光线下不变色。

(2) Good weather resistance: standard thickness oxide film (3 μ m) The anodized aluminum plate is not discolored, corroded, oxidized, or rusted for long-term indoor use. Thickened oxide film (10 μ m) The anodized aluminum plate can be used outdoors and can be exposed to sunlight for a long time without changing color.

（3）金属感强：经阳较处理的铝板表面硬度高，达宝石级，抗刮性好，表面无油漆覆盖，保留铝板金属色泽，突出现代金属感，提高产品档次和附加。

(3) Strong metallic feeling: After anodizing, the surface hardness of the aluminum plate is high, reaching gemstone level, with good scratch resistance. The surface is not covered with paint, retaining the metal color of the aluminum plate, highlighting the modern metallic feeling, and improving the product grade and added value.
