The alloy titanium foil for the production of high-quality sound film is composed of the following weight parts of raw materials: titanium powder 180 ~ 200 parts, tin powder 10 ~ 15 parts, nano titanium dioxide 5 ~ 10 parts, indium powder 5 ~ 10 parts, molybdenum powder 8 ~ 12 parts. The alloy titanium foil for making high-quality sound film has simple processing procedure, and can be made into high-quality sound film with thickness less than 0.05mm as required. The sound film made of the alloy titanium foil of the invention has higher rated power, full and excellent sound color of the middle and high parts, and low distortion degree.
The titanium foil used as a sound film needs to be very thin, and the titanium foil commonly used at present is mostly made of titanium with higher purity, which is difficult to process. The titanium foil made is affected by its own material, so the sound quality of the treble part of the sound film is weak, and the tone distortion of the middle part is high. For the production of high-quality sound film alloy titanium foil, it is composed of the following weight parts: titanium powder 180-200 parts, tin powder 10-15 parts, nano titanium dioxide 5-10 parts, indium powder 5-10 parts, molybdenum powder 8-12 parts;
The preparation method of the alloy titanium foil:
First, titanium powder and tin powder are added to the furnace to melt and stir at high speed. After 15-20 minutes of heat preservation, nano-titanium dioxide, indium powder and molybdenum powder are added. After 20-30 minutes of continuous melting, the resulting mixed molten liquid is poured into the measuring iron tank to cool naturally and make alloy titanium billet;
Then, the obtained alloy titanium billet was placed in the annealing furnace for vacuum annealing at 850-900℃.
Finally, titanium alloy billet is cold-rolled into titanium foil with thickness of 0.02-0.05mm by conventional method.
As a better embodiment of the invention, the raw material consists of 192 parts titanium powder, 13 parts tin powder, 8 parts nano titanium dioxide, 7 parts indium powder, and 9 parts molybdenum powder.
