2. Bismuth bronze - Wikipedia

   en.wikipedia.org/wiki/Bismuth_bronze

   Bismuth bronze or bismuth brass is a copper alloy which typically contains 1-3% bismuth by weight, although some alloys contain over 6% Bi. This bronze alloy is very corrosion-resistant, a property which makes it suitable for use in environments such as the ocean.

3. Free machining steel - Wikipedia

   en.wikipedia.org/wiki/Free_machining_steel

   Free machining steels are carbon steels with added sulfur, lead, bismuth, selenium, tellurium, or phosphorus. Sulfur forms the compound manganese sulfide, which is soft and acts as a chip-breaking discontinuity. It also acts as a dry lubricant to prevent a built-up edge on the cutting tool. Lead works in a similar way to sulfur.

4. Solder - Wikipedia

   en.wikipedia.org/wiki/Solder

   Lead-free solder is prohibited in critical applications, such as aerospace, military and medical projects, because joints are likely to suffer from metal fatigue failure under stress (such as that from thermal expansion and contraction). Although this is a property that conventional leaded solder possesses as well (like any metal), the point at ...

   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.

7. Soldering - Wikipedia

   en.wikipedia.org/wiki/Soldering

   Lead-free construction has also extended to components, pins, and connectors. Most of these pins used copper frames, and either lead, tin, gold or other finishes. Tin finishes are the most popular of lead-free finishes. Nevertheless, this brings up the issue of how to deal with tin whiskers. The current movement brings the electronics industry ...

8. Restriction of Hazardous Substances Directive - Wikipedia

   en.wikipedia.org/wiki/Lead-free

   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; however at this temperature most typical lead-free solders have longer wetting times than eutectic Pb/Sn 37:63 solder.
