Silver alloy material and silver alloy wire

This invention relates to alloy materials and alloy wires, and more particularly to a silver alloy material and a silver alloy wire.

Since the introduction of the phonograph, people have been working on the reproduction of the original sound, and the sound that is expected to be played can be fidelity without distortion. In order to achieve this goal, in addition to ensuring the quality of the radio, the quality of the broadcast equipment is also the key to affect the sound can be fidelity. For audiophiles, not only the specifications of the amplifiers and speakers, but also the quality of the signal lines used to connect the amplifiers and speakers are the focus of the pursuit.

The conventional signal lines are usually copper wire, aluminum wire or copper wire, but they all have high hardness and lead to high difficulty in the line making, which leads to low productivity and yield.

The invention provides a silver alloy material and a silver alloy wire, which can solve the problems of low line yield and poor signal fidelity.

The silver alloy material of the present invention contains silver as a main component and contains at least titanium, gold and palladium, the content of titanium is between 0.2% by weight and 8% by weight, and the content of gold is from 0.1% by weight to 2.5% by weight. The content of palladium is between 0.1% and 3% by weight.

The composition of the silver alloy wire of the present invention is the aforementioned silver alloy material.

In an embodiment of the invention, the silver alloy material further comprises platinum, and the content of platinum is 3% by weight or less.

In an embodiment of the invention, the platinum content is between 1% and 2% by weight.

In an embodiment of the invention, the titanium content is between 0.7% and 6% by weight.

In an embodiment of the invention, the palladium content is between 1.5% and 2.5% by weight.

Based on the above, the silver alloy material and the silver alloy wire of the present invention are not only good for the fidelity of the signal, but also easy to manufacture and can improve the yield and productivity.

The above described features and advantages of the invention will be apparent from the following description.

The silver alloy material of the present invention contains silver as a main component and contains at least titanium, gold and palladium, the content of titanium is between 0.2% by weight and 8% by weight, and the content of gold is from 0.1% by weight to 2.5% by weight. The content of palladium is between 0.1% and 3% by weight. The composition of the silver alloy wire of the present invention is the above-mentioned silver alloy material.

Tests on samples of silver alloy wires made of the above silver alloy materials revealed that the frequency response for sinusoidal waves is distributed between 2 Hz and 820 kHz, while the frequency response for digital waves is distributed between 11 Hz and 32 kHz. Between, it is shown that this silver alloy wire has a wide frequency response range, does not miss high frequency and low frequency sounds, and has a wide range of features. In addition, the DC resistance of the sample of the silver alloy wire is only about 20 mΩ. Such a low impedance is also exhibited in the high-speed signal transmission, and the skin effect is not obvious, so the transmission of the high frequency and low frequency signals is fast and delayed. Small amount to provide high-fidelity sound. Furthermore, samples of silver alloy wire can be easily tested by high temperature and high humidity reliability. By using a single crystal of the above-described silver alloy material to form a silver alloy wire, the defects of crystal distortion are also eliminated, the conductivity is improved, and the original characteristics of various metal materials are extracted.

In an embodiment of the invention, the silver alloy material further comprises platinum, and the content of platinum is 3% by weight or less. The content of platinum is, for example, between 1% by weight and 2% by weight. If the content of platinum is too high, the melting point of the silver alloy material becomes high, the solid solution rate is unstable, and the cost is increased.

In an embodiment of the invention, the titanium content is between 0.7% and 6% by weight.

If the content of gold is less than 0.1% by weight, the hardness of the silver alloy material is too high, which tends to cause workability and yield to be low and the productivity is lowered. If the content of gold exceeds 2.5%, the workability and reliability of the silver alloy material are not significantly improved, and the cost is greatly increased.

In an embodiment of the invention, the palladium content is between 1.5% and 2.5% by weight. If the content of palladium is less than 0.1% by weight, the silver alloy material is hard to pass the high temperature and high humidity reliability test. If the content of palladium is more than 3%, the hardness of the silver alloy material of the present invention is too high, which tends to cause workability and yield to be low and the productivity is lowered.

In the production of a silver alloy material, a metal material such as silver, titanium, gold or palladium is placed in a furnace, and platinum may be selectively added to melt and uniformly mix to obtain a molten alloy liquid. Next, the aforementioned alloy liquid is selectively subjected to ingot making, press roll, heavy drawing, fine drawing, surface cleaning, drying, and setting annealing. (final annealing), rewinding and other processing, can be made into a finished silver alloy wire. The silver alloy wire can be applied to a signal line for transmitting an audio signal, but can also be applied to other fields, and the present invention does not limit it.

In summary, the workability of the silver alloy material and the silver alloy wire of the present invention can increase the yield and productivity, and the fidelity of the signal is also good. When applied to the transmission of sound signals, not only the wide range of sounds, but also the transmission of sound signals of various frequencies is fast and the amount of delay is small, which can provide high-fidelity sound.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention, and any one of ordinary skill in the art can make some changes and refinements without departing from the spirit and scope of the present invention. The scope of the invention is defined by the scope of the appended claims.
