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]
PM 33, crude solder for construction plumbing works, flame-melted, temperature depends on additives Pb 65 Sn 35: 183: 250 [16] Pb: No: Sn35. 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]
60/40: melts between 183–190 °C (361–374 °F) 50/50: melts between 183–215 °C (361–419 °F) For environmental reasons and the introduction of regulations such as the European RoHS ( Restriction of Hazardous Substances Directive ), lead-free solders are becoming more widely used.
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.
Nitronic 50 is used in marine environments, including boat shafting and solid rod rigging. [7] Nitronic 60 and a similar alloy Gall-Tough have high resistance to galling , a form of wear caused by adhesion between sliding surfaces, and metal-to-metal wear.
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/ ...
