虽然民用铝箔是铝的一个重要市场,但是直到最近人们才有点关心这种产品的工艺.众所周知,民用箔(最常用的是10～20微米厚、含99%纯铝)的强度低于其他较厚的相同材料的,尽管已经有一些解释这现象的意图,然而在文献中很少论及.1100合金软状态民用箔材测得的典型极限抗拉强度为65～75兆帕,而相似的较厚板片的极限抗拉强度约为90兆帕.民用箔的伸长率也低于较厚材料的,规格为50毫米长度的铝箔伸长率是2～3%,而较厚的料为35%.大家也知道民用箔与较厚料的拉伸特性有很多不同.
Although aluminum foil for civil use is an important market for aluminum, it has not been a long before people concerned about the process of this product.It is well-known that the strength of consumer foil (most commonly 10 to 20 microns thick with 99% pure aluminum) is lower than the other The same material, thick, has some intent to explain this phenomenon, but is seldom discussed in the literature. The typical ultimate tensile strength of the 1100 soft alloy civilized foil is 65-75 MPa and similar Thicker sheets have an ultimate tensile strength of about 90 MPa. The elongation of a civilian foil is also lower than that of a thicker material, with an elongation of 2 to 3% for a foil of 50 mm length, while a thicker material 35%. We all know that the tensile properties of the consumer foil and the thicker material are quite different.
