Used as a cheaper alternative of Pb 60 Sn 40 for wiping and sweating joints. [52] Pb 60 Sn 40: 183: 238 [11] 247 [16] Pb: No: Sn40, UNS L54915. For soldering of brass and car radiators. [54] For bulk soldering, and where wider melting point range is desired. For joining cables. For wiping and joining lead pipes. For repairs of radiators and ...
Sn 60 Pb 40 solder. Tin-lead (Sn-Pb) solders, also called soft solders, are commercially available with tin concentrations between 5% and 70% by weight. The greater the tin concentration, the greater the solder's tensile and shear strengths. Lead mitigates the formation of tin whiskers, [6] though the precise mechanism for this is unknown. [7]
High-temperature solder, extremely hard, very stiff. 82: In 18: Au 60 Cu 37 In 3: Au–Cu 860/900 [73] – Incuro 60. Lower brazing temperature than other Au–Cu. 37: 60: In 3: Au 20 Cu 68 In 2: Au–Cu 975/1025 [73] – Incuro 20. Cheaper substitute of BAu-3 and other gold-rich gold-copper alloys. 68: 20: In 2: Au 72 Pd 22 Cr 6: Au-Pd 975/ ...
Soldering filler materials are available in many different alloys for differing applications. In electronics assembly, the eutectic alloy with 63% tin and 37% lead (or 60/40, which is almost identical in melting point) has been the alloy of choice. Other alloys are used for plumbing, mechanical assembly, and other applications.
An example SDS, including guidance for handling a hazardous substance and information on its composition and properties. A safety data sheet (SDS), [1] material safety data sheet (MSDS), or product safety data sheet (PSDS) is a document that lists information relating to occupational safety and health for the use of various substances and products.
The more common lead-free solder systems have a higher melting point, e.g. a 30 °C typical difference for tin-silver-copper alloys, but wave soldering temperatures are approximately the same at ~255 °C; [47] however at this temperature most typical lead-free solders have longer wetting times than eutectic Pb/Sn 37:63 solder. [49]
The most common dip soldering operations use zinc-aluminum and tin-lead solders. Solder pot metal: cast iron or steel, electrically heated. Bath temperature: 220 to 260 °C (for binary tin-lead alloys) or 350 to 400 °C (for lead-free alloys) Solder composition: 60% Sn, 40% Pb or eutectic alloy.
The zinc content can vary between few % to about 40%; as long as it is kept under 15%, it does not markedly decrease corrosion resistance of copper. Brasses can be sensitive to selective leaching corrosion under certain conditions, when zinc is leached from the alloy ( dezincification ), leaving behind a spongy copper structure.
