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.

斷續絲紋一般在刷光機或擦紋機上加工制得。制取原理：采用兩組同向旋轉的差動輪，上組為快速旋轉的磨輥，下組為慢速轉動的膠輥，鋁或鋁合金板從兩組輥。

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：陽級氧化鋁板裝飾性強，硬度適中，可輕易折彎成型，進行連續性高速沖壓，方便直接加工成產品，無需再進行復雜的表面處理，大大減短產品生產周期和降低產品生產成本。

(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：標準厚度氧化膜（3μm）的陽較氧化鋁板室內使用長期不變色，不腐蝕，不氧化，不生銹。加厚氧化膜（10μm）的陽較氧化鋁板可使用于室外，可長期暴露于太陽光線下不變色。

(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）金屬感強：經陽較處理的鋁板表面硬度高，達寶石級，抗刮性好，表面無油漆覆蓋，保留鋁板金屬色澤，突出現代金屬感，提高產品檔次和附加。

(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.
