Oyaide SS-47 Audio Grade Silver Solder
Pursuit of the ultimate transparency
The SS-47, the Oyaide original hi-fidelity solder, is produced in order to maximize the capacity of cables and connecters by eliminating its sound character. After the careful consideration of the importance of the contact and joining area, Oyaide finally achieved to produce the high-fidelity audio specialized solder.
They have tried to improve the quality by always selecting best material . There is no exception about this audio grade solder, SS-47. Compared to general solders which usually contain 3N (99.9%) pure tin, SS-47 contains 4N (99.993%) pure tin achieved by excluding impurities to the maximum. Furthermore, 4.7% silver and 1.7% copper are contained for the purpose of improvement of electric conductivity and durability.
As a result of our consideration of flux, it achieved to restrict the corrosion of the surface and residual chlorine to less than 0.12%. In addition, by containing special material, the flux of SS-47 has 83% fast-spreading ratio which indicates great workability.
SS-47 is the ultimate solder which extract maximum performance of components and actualize stress-free craftwork.
