Questions about scrap metals are commonly asked especially by those in the recycling industry. The answer to this is not simple because NORMETALS scrap metal Adelaide do come in a variety of different grades. When you go to sell a copper plate, it would obviously be more valuable compared to a piece of brass. What you need to understand is the grade of the metal before determining its value.
The most commonly found types of scrap metals in a landfill are copper, brass, aluminium, steel and iron. But what happens with other types of metals? Why do they sell for less in a scrap yard? First of all, you need to understand why copper and brass are the most commonly found materials in a landfill. Why is this so? Copper is a non-ferrous metal, which means it is non-toxic even in large doses.
Apart from copper, all other types of metals including sulphide free iron, aluminium, zinc, nickel and tin, are also very common recyclers. What makes them so toxic is their refractory stage in the furnace. The longer they are in this furnace, the more heat they produce. As they heat up, the metals start to diffuse, and this is what makes them soft enough to be recycled. So once they are melted down, and they are put through the recycling machine what you have is all the metallic waste that you can recycle – alloys, copper, brass, iron, aluminium, alloys and iron etc.
So how do you identify the different metals coming into your NORMETALS scrap metal Adelaide recycling business? To begin with, you need to know what each metal is comprised of. For example, brass is made up of three essential elements: Copper, zinc and manganese. All three are light copper, and all three have very different properties when they are in their natural state (chemical state), which is why metals come in three.
There is another way you could test for metals, and this is by sending a piece of scrap metal to a scrap metal recycling company. By doing this, you can identify which metal is part of the original item and therefore would not adversely affect the quality of the product. For example, brass rings are usually made from copper, and they have a finished edge. So, if you send a ring made from brass to a scrap yard and then take it back home and put it on your wrist, you would not harm the ring in any way. You could also use this method to check if copper bracelets are made from copper as well.
