    • An evaporation material is used in manufacturing a VTR tape, a vertical magnetic recording thin film or the like. The evaporation material is a wire comprising a cobalt metal a cobalt--nickel alloy containing not more than 30 weight % of nickel, or a cobalt--chromium alloy containing not more than 30 weight % of chromium. This wire has a diameter of at least 1.0 mm and not more than 10 mm, a tensile strength of at least 400 MPa and not more than 1500 MPa, and an elongation and a reduction of area of at least 5%. The evaporation material has a prescribed crystal structure, with a face centered cubic lattice ratio of at least 0.1 and not more than 1. It is possible to obtain a wire having the above properties by heating the metal material to at least Tu.degree. C. and thereafter performing plastic working of reduction in area of at least 10% in a single pass at a temperature of at least Td.degree. C. and not more than (Tu+200).degree. C. Preferably, the cobalt metal or the cobalt--nickel alloy further contains 0.01 to 0.1 weight % of Mn, Cr, Mg, Zr or Ca. Preferably, the cobalt--chromium alloy further contains 0.01 to 0.1 weight % of Mn, Mg, Zr or Ca.
    • 蒸发材料用于制造VTR带,垂直磁记录薄膜等。 蒸发材料是包含钴金属,含有不超过30重量%的镍的钴 - 镍合金或含有不超过30重量%的铬的钴 - 铬合金的线。 该线材具有至少1.0mm且不大于10mm的直径,至少400MPa且不大于1500MPa的拉伸强度,以及至少5%的伸长率和面积减小。 蒸发材料具有规定的晶体结构,面心立方晶格比至少为0.1且不大于1.通过将金属材料加热至少至少Tu℃,可以获得具有上述性能的线材 然后在至少Td℃和不大于(Tu + 200)℃的温度下,单程中进行至少10%的面积还原的塑性加工。优选地,钴金属或钴 - 镍合金 进一步含有0.01〜0.1重量%的Mn,Cr,Mg,Zr或Ca。 优选钴铬合金还含有0.01〜0.1重量%的Mn,Mg,Zr或Ca。
