Tin alloy wire and flux from the two main parts. Into tin-lead alloy composition, lead-free; flux part of the company after many years of practical experience developing a variety of different formulations of tin solder wire for customers in a targeted selection, each recipe has a different effect, when customers choose understand the product number, to avoid unnecessary quality issues. 
 Commonly used solder alloy type: 
 The proportion of tin-lead alloy composition ingredients, based on customer selection of the appropriate alloy type. 
 Type grade alloy composition (wt%) grades of alloy composition (wt%) 
 Tin-lead alloy 63A Sn63/Pb37 83A Sn45/Pb55 
 80A Sn60/Pb40 84A Sn40/Pb60 
 81A Sn55/Pb45 85A Sn35/Pb65 
 82A Sn50/Pb50 86A Sn30/Pb70 
 Diameter 
 Tin wire diameter from 0.3mm-5.0mm can be customized according to customer demand, usually equipped with: 0.3 mm, 0.5 mm, 0.8 mm, 1.0 mm, 1.2 mm and other specifications. 
 Dapeng tin wire advantages: 
 1, a good soldering performance; 
 2, little welding spatter rosin; 
 3, in-line flux awarded uniform wetting; 
 4, no odor, odorless, non-toxic body of odor, smoke less; 
 5 reel neat, attractive, bright surface. 
 Flux (rosin) type and use: 
 Flux (Rosin) Type Purpose 
 V Series Rosin for electronics and related components, electronic welding, resistance welding of high residue, no leakage, through high-pressure test, the most commonly used in electronic industry, tin wire. 
 M Series no clean applications that require low residue, high insulation resistance, such as the PCB board clean and repair welding. 
 N Series for nickel-plated nickel-based materials, nickel-plated surface components, wire, terminals, sockets, lamp and other hard materials, welding. 
 S Series fire qian welding type for high profile watch, bracelet form, necklace, brooch, shoes, flowers, jewelry, hairpins, etc. burn zinc alloy weld fill processing. 
 T series of special solder wire for stainless steel, zinc alloy, aluminum welding head and other such non-rosin based flux, welding residue can be washed. 
 Solid core solder wire product is solid, without flux, for in the fuse, metal pipe fittings and other special use purposes.
