Premium Grade Audiophile Solder 50G
Oyaide SS-47 hi-fidelity solder is specialized for high-fidelity audio. This is achieved by always selecting best material for our products. Compared to general solders which usually contain 3N (99.9%) pure tin, SS-47 contains 4N (99.993%) pure tin, which is achieved by radical exclusion of impurities. Furthermore, 4.7% silver and 1.7% copper are included for the purpose of improvement of electric conductivity and durability. By this compounding ratio, the electric conductivity was improved spectacularly and we achieved to set eutectic point to 217℃.We were able to reduce surface corrosion and residual chlorine to less than 0.12% with the addition of proprietary materials in the flux, giving it an 83% fast-spreading ratio, resulting in excellent workability. SS-47 is the ultimate solder to achieve maximum performance of components.
Regardless of your soldering skills, you will be pleased with its workability and beautiful finish. We have considered the importance of Skin Effect, the tendency of an alternating electric current (AC) to distribute itself within a conductor so that the current density near the surface of the conductor is greater than that at its core. The surface of SS-47 doesn't disturb electric signal flow or promote electric turbulence. In addition, you can finish the soldering process in seconds when you use a 40W soldering iron because Its wetting temperature (eutectic point) is 217℃, SS-47 is chilled quickly and doesn't damage other materials.

**Please note that the descriptions of Oyaide's products may be roughly translated from Oyaide's Japanese website. I believe they were written by the owner, who is an audiophile, and very passionate about the quality of his products. I will edit these as I discover errors, or wording that did not translate clearly.
Also note that all Oyaide products sold at On Stage Solutions are restricted to U.S. customers, and customers from countries who do not currently have an authorized Oyaide dealer listed here: http://www.oyaide.com/ENGLISH/dealers.html . Any orders placed from countries who have distributors are subject to cancellation. Thank you for understanding.
WARNING of counterfeit products: Please be aware of the counterfeit products of Oyaide AC power plugs and IEC connectors! The best way to avoid the risk of counterfeit products is to always purchase from an authorized dealer. On Stage Solutions is an authorized dealer for Oyaide. If you would like verification of this, please direct your browser to the one and only US distributor for Oyaide (The Lotus Group) on their distributors page, go to their dealers page, and you will see On Stage Solutions listed just past half way down. Here's a quick link (http://www.lotusgroupusa.com/Dealers.htm). I mention this only because I want all of my customers to feel that they can shop with confidence knowing that On Stage Solutions only carries authentic items purchased from official distributors.
