What is the Mohs hardness of tin?
Tin: 1.5. Zinc: 2.5. Gold: 2.5-3. Silver: 2.5-3.
What is the hardness of solder?
The solder matrix, as expected, is very soft, with a hardness of 0.23–0.3 GPa.
Is tin lead a hard solder?
Hard solder Alloys of copper with either zinc or silver are the most common. In silversmithing or jewelry making, special hard solders are used that will pass assay. They contain a high proportion of the metal being soldered and lead is not used in these alloys.

What is solder lead?
Lead solder (aka SNPB solder) is a metal alloy with lead (Pb on the periodic table of elements) and tin (Sn on the periodic table) as its base components. Many years ago, lead pipes and any water supply pipes joined with lead solder were banned in new U.S. plumbing systems.
What is tin and lead?
The key difference between lead and tin is that lead is a metallic grey metal with a blue hue whereas tin is a silvery-white metal with a faint yellow hue. Lead and tin are group 14 chemical elements in the periodic table of elements.
What is tin lead solder?
Tin lead wire is a general-purpose eutectic solder that is widely used to join two metals together. About Tin Lead Wire Solder. Tin lead wire may come in ratios such as 63\% tin to 37\% lead, 60\% tin to 40\% lead or a 50/50\% ratio.
What is the ratio of tin and lead in commonly used solder?
Ideally, solder is 63 percent tin and 37 percent lead. However, it is usually sold as 60 percent tin and 40 percent lead. Terne plate tends to be 75 percent lead and 25 percent tin. However, a 50-percent lead and 50-percent tin alloy can also be used.
Why is lead solder bad?
“Potential exposure routes from soldering include ingestion of lead due to surface contamination. ” Yes, mercury is toxic too—but the toxicity of one heavy metal is hardly a good indicator of how toxic another will be (or the primary effects).
