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 else can I help you with?
What percentage tin antimony lead make type metal?
Type metal typically consists of approximately 12-17% antimony and 82-85% lead, with trace amounts of tin. The percentage of tin in type metal is usually less than 1%.
Does tin contain lead?
No, tin does not contain lead. Tin is a separate element from lead and does not naturally contain lead in its composition.
Would lead and tin nitrate react?
Yes, lead nitrate and tin nitrate can react together to form insoluble lead(II) tin(IV) oxide when subjected to appropriate conditions. This reaction involves the displacement of lead with tin, resulting in the creation of the new compound.
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 two metals make solder?
Any of various fusible alloys, usually tin and lead, used to join metallic parts.
What percentage tin antimony lead make type metal?
Type metal typically consists of approximately 12-17% antimony and 82-85% lead, with trace amounts of tin. The percentage of tin in type metal is usually less than 1%.
What percentage of tin is in solder?
'Standard' solder is 60% tin, and 40% lead. There are other solders available (silver for use in jewellery etc)
Does tin contain lead?
No, tin does not contain lead. Tin is a separate element from lead and does not naturally contain lead in its composition.
What does tin and lead make?
Tin and lead makes pewter
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
Which metal was often confused with lead and tin?
Zinc was often confused with lead and tin due to their similar appearances. However, zinc has a higher melting point than lead and tin, and it does not oxidize easily like lead and tin.
What metal alloy does tin and lead make?
Definition - Terne is an alloy coating of lead and tin used to cover steel, in the ratio of 20% tin and 80% lead. Terne is used to coat sheet steel to inhibit corrosion. It is the one of the cheapest alloys suitable for this, and the tin content is kept at a minimum while still adhering to a hot-dipped iron sheet, to minimize the cost.
Which element has more protons in the nucleus of its atoms tin or lead?
Lead has more protons. Lead contains 82 protons, while tin only contains 50.
What is more conductive out of lead tin and solder?
Tin is more conductive. Lead is used to ease application.
Would lead and tin nitrate react?
Yes, lead nitrate and tin nitrate can react together to form insoluble lead(II) tin(IV) oxide when subjected to appropriate conditions. This reaction involves the displacement of lead with tin, resulting in the creation of the new compound.
