Product Description
Sn90Sb10 Solder Preforms

Features:
-    Lead-free solder
-    Melting range 240~250 ºC
-    Good creep resistance
-    Good mechanical performance

Description:
Due to narrow melting range, good mechanical performance and low cost, Sn90Sb10 alloy is widely used as a high temperature lead-free solder. The mechanical properties of the solder will be improved with the increase of Sb content in the alloy. High Sb content will lead to brittleness of the solder and poor electrical and thermal conductivity, so the mass fraction of Sb in Sn-Sb solder commonly used will not exceed 10%. Although the wettability of Sn90Sb10 is slightly lower than that of Sn63Pb37, Sn-Sb alloy has the best creep resistance under low stress.
