The outcome of the test of the sample's major metal components shows, the material type of 90 per cent of the sample carriers of China's remaining wire-recorded sound archive of traditional and folk music is 18/8 type Chromium-Nickel stainless steel, whose chemical properties have remained intact till today. The parametric test of the sample's major physical property of being magnetic shows, the carriers'physical property of being magnetic has stayed in complete conformity to the conditions of ferromagnetic materials serving as the material for audio signal recording and storage.

样本主要金属成份含量测试结果显示：本课题重点考察的我国钢丝录音遗存音乐音响档案载体品种中90%的材质类型为18/8铬镍不锈钢，它们的化学特性至今仍然保持完整；样本主要物理磁特性参量测试结果显示：这批音响档案载体的物理磁特性完全符合铁磁性材料作为音频信息记录及保存介质材料的基本条件。

Pyrite,pyrrhotite and pentlandite in order of gold content.

载金的硫化铁矿物成分主要是黄铁矿，其次是磁黄铁矿和镍黄铁矿。

Crystal size of the iron based alloy foil is less than 10μm, while the crystal size of the nickel based alloy foil is about 2μm. Results show that the electrodeposited Fe-Ni foil has better magnetic properties than conventional milled Permalloy 1J79 foil.

实验表明：电沉积铁基合金箔晶粒小于10 μm，电沉积镍基合金箔晶粒大小在2 μm左右；电沉积Fe-Ni合金箔是一种性能良好的软磁材料，其基本磁性能优于传统熔铸-轧制坡莫合金1J79。

These include iron, nickel, cobalt, and some rare earth metals.
