Scrap Aluminium

The collection and sale of scrap metal can be quite a lucrative business, providing that you pay careful attention to the proper details. Scrap prices are known to fluctuate on a weekly or even a daily basis (due to a number of different factors), and it is important that you keep an eye on these fluctuations if you want to get a good idea of what your metal is worth.

To begin with, you will need to ensure that you have separated your scrap into its relevant types. The reason for this is that each metal will have a different worth, and it is easier to work out how much you will make if you do each type separately.

You will then need to begin developing good relationships with the scrap metal dealers in your area. Prices can fluctuate depending on who you are dealing with, so it always pays to compare the prices offered by a few local dealers and going with the one who offers you the most. By developing a good relationship with this person, you will have an ‘in’ whenever you want to know how much aluminium or copper is going for.

You could also try visiting your local recycling centre or doing some research online to see what other people are currently paying for scrap. You might be able to get your hands on a scrap metal pricing chart, which could be invaluable for determining the best times to sell.

At the end of the day, the worth of your scrap metal will differ depending on the time of year, month and even week that you are trying to sell it. Once you have been buying and selling for a while, however, you will begin to become familiar with the trends in pricing, as well as developing an instinct for when you should sell and when you should hold onto your metal for a little longer.

Brass is a man-made alloy that is made up of varying combinations of copper and zinc. Other metals can be added to the mix, however, in order to create brass that embodies different properties, such as colour and strength. If you have an item that you think might be brass, there is a way to test it both at home and in the workplace to determine whether you are correct or not.

Step 1: Weigh the metal (in pounds) using a set of scales. Then, convert this number to kilograms by dividing it by 2.2046 (since this is how heavy a single kilogram is in pounds).

Step 2: Take a graduated beaker and fill it with water until you reach the 100ml line. Drop the item you suspect is brass into the beaker, watching how high the water level rises. Record the new level. Then, subtract the first water level from the second, which leaves you with the volume of the item.

Step 3: As a milliliter is equivalent to a cubic centimeter, you are now able to convert the volume of the suspected brass item into cubic meters by dividing it by 1,000,000 cubic centimeters per cubic meter.

Step 4: Now you can divide the mass of the item by the volume, which will leave you with the density of the item in kilograms per cubic meter. If the density falls into the known range for brass, you can conclude that that is the metal you are working with.

Whilst this is not the easiest of tests to complete, as you are required to have a number of unusual tools on hand, it is one way that you can definitively determine whether the metal you are working with is brass or not. If the density is not in the known range for brass, check other ranges to work out what type of metal the item is.

These days purchase rate of aluminium is recorded all time high in construction industry. A decade back steel was considered the only material used in building structures, however in recent time things have changed and the uses of aluminium has rapidly increased in past few years. But what has made this metal so much in demand? Well, there are various for this.

Firstly, they are resistant to corrosion that is highly beneficial for buildings as they are likely get wet in almost every season. It is not necessary that only rain can be the cause of corrosion, but moisture in the air can also decay metallic element. However, aluminium cannot alone be 100% resistant to corrosion, because they have the tendency to oxidize. Therefore it has to be mixed with other alloys.

Secondly, it has light weight. Anything made with aluminium is lighter in weight that in turn makes the product easier to install and creates less pressure on the structure. With this metal a large varieties of product can be created, for instance door frames, windows, skylights, cladding, gutters and roofing. Another benefit of using aluminium cladding which is insulated is that they are thermally efficient. They can keep home warm in winters and cool in summers. The plus point is that single layer of insulated aluminium cladding is equally effective as four inches brick or stone wall.

Next, aluminium can be cut into any shape and size. It can be welded, curved, bonded and tapered for any job because of its ductile nature. Also, it can be a good beauty booster for building. By painting this metal with desired color and using it with other material it can be used as beauty feature in any building. With so much of benefit, it is not surprising if they are being widely accepted in construction.
