Lead. The densities of lead and tin are 11.34 g/cm^3 and ~7 g/cm^3, respectively. Lead solder is an alloy made of mostly lead and tin; a mixture of lead and tin will weigh less than 100% lead. Lead-free solders are made of tin, copper, silver, indium, bismuth, zinc, antimony, and other metals; none of these metals is heavier than lead. So, lead is the champion.
What else can I help you with?
What is heavier water or lead?
Lead (11,34 g.cm^-3) has a greater density than water (1 g.cm^-3) so for the same volume of water and lead, lead will be heavier. The "-3" should be written as an exponent but it won't allow me
Can the alloy plumber's solder be both substitutional and interstitial?
Plumber's solder is typically a eutectic alloy composed of metals like tin and lead. These types of alloys are usually substitutional, where atoms of different sizes can replace each other in the crystal lattice. However, in certain cases, impurities or small amounts of other elements may occupy interstitial positions in the lattice, making the solder both substitutional and interstitial to a limited extent.
Which is heavier wood or lead?
Because centimeters cubed is a unit of volume, not weight. The two might take up the same amount of space, but iron is much more dense and as such weighs more.
What are things made up of lead?
Lead has many uses and applications, and was even more commonly used in the past:Stained glass windows, especially in older churches, use lead to hold the glass pieces in place;some boats strap pure lead blocks to their hulls to prevent corrosion by galvanisation;fishing sinkers, bullets and shot shells are mostly lead because of its density;car batteries use a reaction with lead to create energy;the solder in most circuits uses lead;pewter mugs and other items (now a health hazard) contain lead;lead is used as shielding in radioactive situations (x-ray rooms, radiation suits and other such areas);Environmental concerns have led to restrictions on lead used in paints, but many homes built in the 20th century and before may have these potentially toxic paints.Electronic devices should not be disposed of in landfills but rather be properly recycled.
What does lead mean in science?
Lead is a heavy metal. An element. Atomic number 82 (has 82 protons in nucleus). Symbol is Pb, which comes from its Latin name plumbum. It is also the most nuclear stable element. That is, it is the end product of fusion. It is the heaviest element that is produced under normal fusion conditions in a star. Heavier elements (produced usually in supernova) decay usually into 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.
Solder is made of tin and lead but what is the other chemical?
Traditional electronics solder also contains resin.
What is the chemical formula for solder?
The chemical formula for solder can vary depending on the type of solder being used, but a common formula is Sn (tin) mixed with Pb (lead), known as Sn-Pb solder. The ratio of tin to lead can differ, with common ratios being 60% tin and 40% lead (60/40 solder) or 63% tin and 37% lead (63/37 solder).
What is the compound symbol for solder?
The compound symbol for solder can vary depending on the specific composition. Common solder compounds include tin-lead solder (Sn-Pb) and lead-free solder such as tin-silver-copper (Sn-Ag-Cu) or tin-copper (Sn-Cu).
How do you solder electric wires to a brass fitting?
*Yes you can solder brass, as long as it isn't the decorative polished brass. They have used brass fittings in plumbing for years and years. It has the same characteristics as copper.
Do plumbers use solder?
Yes many types depending on application and lead free alloys as solder by definition means lead. Solder such as 40 - 60 50 -50 60- 40
Is solder a lead alloy?
Most commonly, but antimony is another basic component of some solders. The European Union, China, and California are areas where lead solder is banned in consumer products. Tin-lead solders were most often used because they are easily melted and inexpensive. Lead-based solders have a few problems which are reducing their popularity: - Environmental concerns about e-waste - Worker safety concerns for people who constantly work with solder - The low melting point, which is not suitable for modern microprocessors Any metal which is melted to bond to another metal is a solder. Silver solder is used to repair silver jewelry, and gold solder to repair gold. Silver solder is also used in food-grade plumbing. Drinking water is soldered with lead-free solder (but lead was used in nearly all plumbing soldering until the late 1980s).
Is solder a element or a compound?
It is a mixture
What products are made using soft solder?
soft solder is made of tin and lead. :D
Which alloy is made from tin and lead?
Solder
What type of solder is used in electronics and why?
lead.
Why is lead-free solder used?
Lead is toxic to humans (causes brain damage) thus when using a solder to join copper water pipes it is best not to use a solder containing lead as this will get into the water passing through the pipes and slowly poison the user of this water.
