Introducing Mitsuya's recommended joint plating!
■Gold-Tin Alloy Plating Gold-tin alloy plating is an optimal alloy plating for high-temperature lead-free solder materials, with a melting point of 280°C, achieved through an 80% gold and 20% tin eutectic composition. ■Tin-Antimony Alloy Plating Compared to regular tin plating, it excels in preventing tin pest and has superior heat cycle durability. ■Indium Plating Indium has a very soft, dull white appearance and is prone to scratching. Its hardness is below Hv5, and its melting point is 156.6°C. It has a proven track record in preventing contact failure as a joining tool for bundling vessels.
