About the product
The KR-19 lead-free solder wire with low processing temperature is a success story with rocket propulsion. In the truest sense of the word. Ever since NASA experts first used the predecessor of KR-19 in space travel over 30 years ago, its success has continued unabated. Almit's KR-19 flux (classification ROM1) is suitable for through-hole soldering and drag soldering applications and guarantees optimum results when soldering on aluminum, nickel and stainless steel surfaces. The alloy LFM-48 (Sn-3.0Ag-0.5Cu, melting range 217-220°C) is a SAC305 alloy and is recommended by the Japan Electronics and Information Technology Industries Association (JEITA). Lead-free solder wire, Sn-3.0Ag-0.5Cu, 217° - 220°C, ROM1, Flux 3.5%, For surfaces that are particularly difficult to solder.
