because they are not semiconductors. They are metals and rather good conductors.
Tin, lead, cadmium and bismuth.
It is a semiconductor
Solder Also Pewter is a malleable metal alloy, traditionally 85-99% tin, with the remainder consisting of copper, antimony, bismuth and lead.
Soldering wire is usually made of a combination of tin and lead. The most common ratio is 60% tin and 40% lead. However, due to environmental and health concerns, lead-free solder wire made of tin, silver, and copper is also widely used now.
Semiconductor raw materials like silicon, germanium, and selenium are the purest substances that you will have a chance to encounter. However the process of making semiconductor devices deliberately contaminate the semiconductor with controlled amounts of various impurities. Other semiconductors like gallium arsenide and the semiconductors used in LEDs are alloys. Other semiconductors like cadmium sulfide and lead sulfide (galena) are compounds.
Tin (Sb) is a poor metal.
Tin can poisoning was from the lead (metal) that used to be used to seal tin cans. It is no longer used.
Tin is more conductive. Lead is used to ease application.
solder tin, lead,
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.
Germanium is an element that exhibits similar behavior to silicon and lead. It shares some properties with silicon, such as being a semiconductor, and also shares some properties with lead, such as being a metalloid.
No, tin does not contain lead. Tin is a separate element from lead and does not naturally contain lead in its composition.
Lead and tin...
Tin, lead, cadmium and bismuth.
Tin and lead makes pewter
Any of various fusible alloys, usually tin and lead, used to join metallic parts.
About half of all tin that is produced is used for solder. This is usually used for joining electric circuits. Tin is used for coating lead, zinc of steel to prevent corrosion. Tin is used in many specialized alloys including pewter and bronze. It is also used to create a special type of bronze called bell metal that is used for making bells. Tin, together with lead, is also used in the metal pipes of the pipe organ.
