鋁型材的裂紋是由于拉伸應力引起的表面不同程度的橫向撕裂引起的。鋁板生產廠家經過分析，造成這種現象的主要原因如下:
　　The cracks of aluminum profiles are caused by different degrees of transverse tears on the surface caused by tensile stress. After analysis, the main reasons for this phenomenon are as follows:
　　，由于摩擦，金屬表面受到附加拉應力的作用。當附加拉伸應力大于金屬表面的拉伸強度時，就會產生裂紋。
　　Firstly, due to friction, the metal surface is affected by additional tensile stress. When the additional tensile stress is greater than the tensile strength of the metal surface, cracks will occur.

　　第二，擠壓溫度過高，金屬表面抗拉強度下降，在摩擦作用下產生裂紋。
　　Secondly, when the extrusion temperature is too high, the tensile strength of the metal surface decreases and cracks are produced under the action of friction.
　　第三，當擠壓速度過快時，金屬表面通過加加拉應力來增大型材產生裂紋。
　　Third, when the extrusion speed is too fast, the metal surface cracks by adding tensile stress.
　　要解決這一問題，只有嚴格控制擠出工藝參數，保證合理的出口速度和出口溫度，才能減少裂紋現象。這就要求公司對生產過程進行嚴格的檢查和監督。
　　In order to solve this problem, the crack can be reduced only by strictly controlling the extrusion process parameters and ensuring the reasonable exit speed and temperature. This requires the company to strictly inspect and supervise the production process.
