The unidirectional solidification pure silver wire produced by Taiwan Rainbow Co., Ltd. is made of high-purity
silver grains and silver alloy wires are made from high-purity silver grains and other elements as raw materials. For assuring product quality, TRC adopts the advanced continuous casting technique to produce unidirectional crystal pure silver wire/silver alloy wires.

The advantages of product include：

Minimum Impurity Content：In the vacuum process, impurities can be eliminated more effectively.

Low Gas Content：TRC adopts vacuum casting technique to remove oxygen and hydrogen from the melt that can reduce signal loss during audio transmission. Therefore, the signal can pass unimpeded. For silver-gold alloy, there is no significant oxidation happened and anti-electromagnetic interference is one of its key features.

Orderly Crystal Structure：The wire produced by TRC has long crystal and unidirectional solidification that eliminates audio distortion as possible because of less crystal boundaries. Moreover, audio tones including low, medium and high tones are distinct and clear to represent excellent performance.

Excellent Conductivity：The wire has outstanding characteristics including high conductivity, high thermal conductivity and corrosion resistivity.
