What is soder made out of?
Soder used to be made of a mixture of tin and lead. But when it was discovered that lead was poisonus, it changed to a mixture of mainly tin.
What metals does a pewter cup contain?
Pewter is an alloy composed mainly of tin, with small amounts of antimony, copper, and sometimes bismuth.
What two metals make solder?
Any of various fusible alloys, usually tin and lead, used to join metallic parts.
Which elements contain four valence electrons?
Elements in Group 14 (Carbon family) contain four valence electrons. These elements include carbon, silicon, germanium, tin, and lead.
Is lead solder a ferrous metal?
No, lead solder is not a ferrous metal. Ferrous metals contain iron, while lead solder is primarily composed of tin and lead.
What does a pewter cup contain?
tin, copper, lead, antimony

What percentage is lead and tin?
If the question relates to solder or tin-lead plating of electronic components to prevent tin whiskers from growing then the answer is a minimum of 3% lead in the tin solder. Eutectic tin-lead solder for electronics is 63% tin 37% lead. Due to the European Union's lead ban (environmental regulation called RoHS), non-lead tin solders have been developed; SAC alloys (tin-silver-copper) being most common. A higher temperature is required to melt solders that do not contain lead. As of this writing (Oct 2010), there is no adequate substitute for lead. Tin whiskers may grow and eventually cause electronic products to fail and we do not know why that happens or how long it takes for them to grow. One scientist at NASA aptly summarized the situation: "Sometimes tin whiskers" For sheetmetal (copper, tin plate, galvanized steel plate soldering, 50% tin - 50% lead is preferred. 50-50 was used for copper plumbing until lead was banned (concerns about water quality). Silver replaced the lead and a higher temperature was required to melt it.
What is the percent composition of solder?
Solder is a fusible alloy that is used to join less fusible metals or wires,Combinations of tin and lead are most common, in ratios of 60 percent tin to 40 percent lead; 63 percent tin to 37 percent lead; and 50 percent tin to 50 percent lead.
What metals does a pewer cup contain?
Nowadays, pewter is mainly an alloy of tin (95-96%) and copper. But in the past it could also contain antimony, bismuth and lead.
Does lead react with tin nitrate?
No, lead does not react with tin nitrate under normal conditions. Lead is a less reactive metal and is unlikely to displace tin in a compound like tin nitrate.
Is lead stronger than tin?
no cause its TIN TIN THE MOVIE
