2. Fusible alloy - Wikipedia

   en.wikipedia.org/wiki/Fusible_alloy

   Fusible alloys are typically made from low melting metals. There are 14 low melting metallic elements that are stable for practical handling. These are in 2 distinct groups: The 5 alkali metals have 1 s electron and melt between +181 (Li) and +28 (Cs) Celsius; The 9 poor metals have 10 d electrons and from none (Zn, Cd, Hg) to three (Bi) p electrons, they melt between -38 (Hg) and +419 (Zn ...

3. List of brazing alloys - Wikipedia

   en.wikipedia.org/wiki/List_of_brazing_alloys

   Lowest melting point alloy with low vapor pressure. 80: 20: Au 88 Ge 12: Au 356 [54] – Au88, Indalloy 183, Premabraze 880, Georo. Eutectic. Low ductility. Used for die attachment of some chips. The high temperature may be detrimental to the chips and limits reworkability. Very low vapor pressure. 88: Ge 12: Ag 90 Ge 10: Ag 651/790 [73 ...

   en.wikipedia.org/wiki/Melting_points_of_the...

   The Gmelin rare earths handbook lists 1522 °C and 1550 °C as two melting points given in the literature, the most recent reference [Handbook on the chemistry and physics of rare earths, vol.12 (1989)] is given with 1529 °C.

5. Solder alloys - Wikipedia

   en.wikipedia.org/wiki/Solder_alloys

   Good fatigue resistance combined with low melting point. Reasonable shear strength and fatigue properties. Combination with lead-tin solder may dramatically lower melting point and lead to joint failure.

6. Pewter - Wikipedia

   en.wikipedia.org/wiki/Pewter

   Pewter (/ ˈ p juː t ər /) is a malleable metal alloy consisting of tin (85–99%), antimony (approximately 5–10%), copper (2%), bismuth, and sometimes silver. [1] In the past, it was an alloy of tin and lead , but most modern pewter, in order to prevent lead poisoning , is not made with lead.

7. Metal roof - Wikipedia

   en.wikipedia.org/wiki/Metal_roof

   A metal roof is a roofing system featuring metal pieces or tiles exhibiting corrosion resistance, impermeability to water, and long life. It is a component of the building envelope . The metal pieces may be a covering on a structural, non-waterproof roof, or they could be self-supporting sheets.
