Foil is a thin metal sheet, such as Titanium Foil Roll, copper foil, aluminum foil, etc. specifically, any metal sheet with a thickness of less than 0.2mm is called a foil. According to the thickness of metal foil, it is divided into thick foil, single zero foil, and double zero foil. Among them, the thickness of the thick foil is ＜ 0.2mm --≥ 0.1mm, the thickness of single zero foil is ＜ 0.1mm - ≥ 0.09mm, the thickness of double zero foil is ≤ 0.001mm, and the thickness of the thinnest foil that can be rolled industrially is 0.0045mm. At present, the output of aluminum foil is the largest, accounting for almost more than 85% of the total output of metal foil in the world. China is the world's largest aluminum foil producer and exporter. In 2020, the output will reach 4050kt, accounting for about 65% of the global total, and the export volume will account for 30% of the output, reaching 1215kt.
Titanium Foil Roll is difficult to produce, with a high price and low output. It is estimated that the world's output will not exceed 20 tons in 2020. The main production country is the United States, which is not widely used. Aircraft skin thermal insulation material is one of its high-end application products. as we all know, when the aircraft flies in the air, its outer metal skin will heat up due to fierce friction with the air and other reasons. In order not to transfer heat into the interior, a thermal insulation protection layer must be set (Fig. 1).
It is welded by four layers of heat insulation plates, and a thinner flat sheet is sandwiched in the middle. Figure 2 shows the parts of the heat shield, which are made of 0.08mm TB2 alloy foil. TB2 is a β Type titanium alloy, ti-5mo-5v-8cr-3al alloy (mass%): al2.5-3.5, mo4.7-5.7, v4.7-5.7, cr7.5-8.5, fe0.30, c0.05, n0.04, h0.015, o0.15, other impurities 0.1 each, 0.4 in total, and the rest ti.
