划伤现象：划伤现象是剪切国产中比较常见的现象，在铝板推进剪切机的国产中会与剪切机的进料口摩擦，出现划伤，影响到了铝板表面外观质量，如果对板面质量要求高的用户建议覆膜以后(表面覆膜，保护铝板)在进行剪切加工，通常覆膜费用为2元/平方米。
Scratch phenomenon: Scratch phenomenon is a common phenomenon in domestic shearing. In the domestic production of aluminum plate pushing shear machines, it will rub against the feed port of the shear machine, causing scratches, which affect the surface appearance quality of the aluminum plate. If users have high requirements for the surface quality of the plate, it is recommended to use film coating (surface coating to protect the aluminum plate) for shearing processing after laminating, and the film coating cost is usually 2 yuan/square meter.
尺寸准确：长度，宽度要准确合理，对角线公差控制在1-2mm之间，当然，对于小规格铝板的剪切不能控制如此精密切边整齐：部分剪板机的剪切刀由于不锋利，而导致铝板切边边缘不整齐，建议在加工时寻找大型的加工企业以及新式的加工设备。
Accurate size: The length and width should be accurate and reasonable, and the diagonal tolerance should be controlled between 1-2mm. Of course, for the cutting of small-sized aluminum plates, it cannot be controlled to be so precise and neat. Some of the cutting blades of the plate cutting machine are not sharp, resulting in irregular cutting edges of the aluminum plate. It is recommended to seek large-scale processing enterprises and new processing equipment during processing.
超宽铝板是众多铝板产品中较为特殊的一种，一般认为，宽度在1500mm以上的被称为宽铝板，2000mm以上的被称为超宽铝板。
Ultra wide aluminum plate is a special type among numerous aluminum plate products. It is generally believed that those with a width of over 1500mm are referred to as wide aluminum plates, while those with a width of over 2000mm are referred to as ultra wide aluminum plates.
超宽铝板的生产要求很高，不是任何厂家都能生产的！
The production requirements for ultra wide aluminum plates are very high, and not any manufacturer can produce them!
生产设备来讲，超宽铝板对轧制幅度的宽度要求较高，一般设备不能满足，尤其是2000mm以上的铝板产品。从铝板厂家讲，对制造企业的生产能力有更高的要求，要在较宽幅度上达到性能稳定。就目前来说，仅有一部分实力较强的大型厂家能够满足这一生产要求。
In terms of production equipment, ultra wide aluminum plates have high requirements for the width of the rolling range, which cannot be met by general equipment, especially for aluminum plate products above 2000mm. From the perspective of aluminum sheet manufacturers, there are higher requirements for the production capacity of manufacturing enterprises to achieve stable performance over a wide range. Currently, only a portion of large manufacturers with strong capabilities can meet this production requirement.
目前市场上常用的超宽铝板合金以5系、6系为主，常用合金是5052-H112、6061-T6等，超宽铝板前景光明，在一些新兴的船舶制造、汽车配件、电子设备、精密机械等强势产业上有很大的市场空间。
At present, the commonly used ultra wide aluminum sheet alloys in the market are mainly 5 series and 6 series, with commonly used alloys such as 5052-H112 and 6061-T6. The prospect of ultra wide aluminum sheet is bright, and there is great market space in some emerging strong industries such as shipbuilding, automotive parts, electronic equipment, and precision machinery.
