Posted: April 29, 2014
Alloys and elements can be confusing, but knowing the difference could help you when you are looking for items to scrap. Metals are worth more than alloys which makes a difference at the scale. Here are some helpful facts about alloys that might help you out on your next scrap adventure. (Find updated prices here.)
– An alloy is a blend of 2 or more elements.
– Stainless steel is an alloy of iron, carbon and chromium. The chromium is added in a thin layer surrounding the surface of steel to prevent oxygen from causing rust.
-Solder, used to bond metals to other metals, is an alloy of tin and lead. Sometimes silver is added to solder to be used in creating sterling silver jewelry.
– Brass is a very common alloy used in plumbing pipes. It is made mostly from copper and zinc. Sometimes brass may be referred as a type of bronze. This is because bronze is an alloy of copper and other metals but usually tin.
– Although many alloys contain the word “silver,” a lot of them don’t actually contain silver, such as Tibetan silver.
– Pewter is an alloy of tin containing 85-99% tin with copper, bismuth, lead and/or silver.
– When an alloy is considered “lead-free,” this means that it contains no more than .05% lead.
– Gold is considered a pure metal but most gold seen on a daily basis is an alloy. The amount of gold in an alloy is expressed in Karats. Anything less than 24 karats is considered an alloy and will be mixed with a range of different metals.
Remember, the more pure your metals are the more they are worth. When you know you have different types of materials be sure to keep them separated so that you don’t end up losing money at the scale. Find more ways to earn money on our YouTube page or send us any questions you may have here.
