These bars come with designs that are either simply the logo of the company refining the silver or feature more elegant designs that the refinery experiences such demand for that it is continuously offered. The TC alloy (S-Sn99.3Cu0.7) is a lead-free solder, which replaces eutectic or almost eutectic tin-lead alloys at the lowest possible cost. There are silver bars that are continuously produced and sold by refineries and mints. Up to 90% of the expensive silver can be reduced, although the properties are virtually the same during the soldering process. Lower silver reduces the price and a lopper content ensures less maintenance.Įven more favourable is the alloy TSC0307, which has a composition of 99% tin and only 0.3% silver and 0.7% copper. The alloy TSC305 (Sn96.5Ag3.0Cu0.5) with a lower silver content has become an industrial standard alloy over the last years. The eutectic alloy TSC with Sn95.5Ag3.8Cu0.7 should be highlighted due to its low melting point of 217☌ and excellent wetting properties. TSC alloys are available in different compositions and vary by the ratio of tin, silver and copper. K100LD Lead-Free, Silver-Free Alloy Bar Solder K100LD is a eutectic Tin/Copper alloy with controlled metallic dopants to control the grain structure within the solder joint, and to minimize the dissolution of copper into the solder pot. The adding of additives changes the crystal structure of solder joints, reduce internal stress and inhibits the growth of crystal.Lead-free solders, based on pure tin with an addition of silver and/or copper, are suitable for all lead-free applications in electronics manufacturing.įor the production of electronics, ECOLOY TSC alloys (Tin, Silver, Copper) are a reliable lead-free option. Excellent anti-oxidant and lower tin slag 4.Good mechanical properties of solder joints 5.
Smooth surface ,Good fluidity, wetting property and bright solder joints 2.
tin lead free soldering rods for pcb welding f eatures 1. High Quality Solder is supplied in all specifications including lead-free solder and is available in ingot, bar, plumbers sticks, body solder, tinmans, blowpipe, solder pellets, rings, solid solder wire and flux cored solder wires.
Good wetting and solderability, under excellent antioxidant, little drosspot produced, with full light spot after dip soldering,The products have good solder results, no adhesion and no corrosive, invasion speed,and satisfy the requirements of rapid welding manual. Tin lead free soldering rods for pcb welding tin lead free soldering rods for pcb welding instructions Lead-free solder compared with traditional lead solder(Sn-Cu),The biggest drawback of Lead-free solder is not good at the infiltrative,and the diffusion rates is also worse than 10% ,solder bars are produced by high-purity tin and electrolytic lead, with clean and bright appearance. The adding of additives changes the crystal structure of solder joints, reduce internal stress and inhibits the growth of crystal. For example, a lead-free alloy such as silver solder might be by composition 94 tin and 6 silver. Most solders are alloys of one or more elements. Gold bullion investors are constantly buying and marketing these bars, producing them one of the nearly all popular ways to commit in physical silver. platinum solder, gold solder, and silver solder, which are higher temperature solders used as jewelers’ solder. Smooth surface ,Good fluidity, wetting property and bright solder joints 2. Sterling silver bars are usually 99.9 pct natural silver that offers been dissolved down and minted into pub form in myriad sizes. lead/pb free tin solder bar,tin bar,soldering bar,solder stick/rod f eatures 1. High quanlity tin electronic soldering metal, soldering bar tin electronic soldering metal, soldering bar instructions Lead-free solder compared with traditional lead solder(Sn-Cu),The biggest drawback of Lead-free solder is not good at the infiltrative,and the diffusion rates is also worse than 10% ,solder bars are produced by high-purity tin and electrolytic lead, with clean and bright appearance.
