   en.wikipedia.org/wiki/List_of_brazing_alloys

   Free-flowing, for ferrous alloys, nickel, copper and their alloys, and combinations. Tin content improves wetting of tungsten carbide, stainless steel, and other difficult metals. Absence of lead and cadmium allows use of long heating cycles. Cheaper alternative of BAg-28 with similar properties. Suitable for fluxless controlled atmosphere brazing.

   en.wikipedia.org/wiki/Brass

   Islamic Golden Age brass astrolabe Brass lectern with an eagle. Attributed to Aert van Tricht, Limburg (Netherlands), c. 1500.. Brass is an alloy of copper and zinc, in proportions which can be varied to achieve different colours and mechanical, electrical, acoustic and chemical properties, [1] but copper typically has the larger proportion, generally 2 ⁄ 3 copper and 1 ⁄ 3 zinc.

4. Brazing - Wikipedia

   en.wikipedia.org/wiki/Brazing

   High-quality brazed joints require that parts be closely fitted with base metal surfaces exceptionally clean and free of oxides. In most cases, joint clearances of 0.03 to 0.08 mm (0.0012 to 0.0031 in) are recommended for the best capillary action and joint strength; [ 6 ] in some brazing operations, however, it is not uncommon to have joint ...

5. Wood's metal - Wikipedia

   en.wikipedia.org/wiki/Wood's_metal

   Wood's metal is toxic because it contains lead and cadmium, and contamination of bare skin is considered harmful. Vapour from cadmium-containing alloys is also known to pose a danger to humans. [ 9 ] Cadmium poisoning carries the risk [ 10 ] of cancer , anosmia (loss of sense of smell), and damage to the liver, kidneys, nerves, bones, and ...

   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.

8. Babbitt (alloy) - Wikipedia

   en.wikipedia.org/wiki/Babbitt_(alloy)

   The rods and caps would have shims that could be peeled off as the Babbitt wore down. Ford was known to use two 0.002" on each cap and Babbitt that was 86% tin, 7% copper, 7% antimony (see the KRW catalogs for the Model T). Steel shims were used, as the brass shims used today tend to compress over time, contributing to shorter bearing life. The ...

   EPA illustration of lead sources in residential buildings Infographic about lead in drinking water. The Lead and Copper Rule (LCR) is a United States federal regulation that limits the concentration of lead and copper allowed in public drinking water at the consumer's tap, as well as limiting the permissible amount of pipe corrosion occurring due to the water itself.
