Weight: 227 g (0. 5 lb) Diameter: 0. 63 mm (0. 025 in) Gauge: 23 The MG Chemicals 4894 Sn60 Pb40 RA Solder Wire is electronics grade solder wire. The 60 40 rosin core solder uses a classic tin to lead alloy ratio complemented by a RA like flux core. This solder wire meets J STD 004B, ASTM B 32, and exceeds J STD 006C specifications. It melts at slightly higher temperatures and over a wider temperature range than 63 37 solder. This results in robust and reliable joints that are highly resistant to whisker formation. These 60 40 leaded solders achieve a consistent solder and flux percentage thanks to our state of the art extrusion wire drawing machine, which continuously monitors the wire to prevent voids and ensure consistency, resulting in a top grade solder wire. Features & Benefits Alloy exceeds J STD 006C and meets ASTM B 32 purity requirements Flux meets J STD 004B Rosin activated flux Fast wetting Fast flowing Non corrosive residue Non conductive residue
