Bronze is an alloy of copper and tin. Its base metal—copper—is known for its many useful properties, including corrosion resistance, malleability, and electrical conductivity. But copper has one prominent characteristic that sets it apart from other non-ferrous metals—it forms patina when exposed to oxygen.
Patina is a green or brown film that develops on the surface of copper, its alloys, and similar metals through a long period of oxidation. The patina that develops on copper starts off as pure brown and finally turns into hues of blue and green. One popular example of copper that has successfully formed patina after constant exposure to the elements is the Stature of Liberty.
This special quality of copper does not go away when it is alloyed with other metals. Therefore, bronze, is also capable of producing patina. In fact, its characteristic greenish-brown hue after many years of oxidation is a type of patina. And despite being stain by nature, it is one of the things that people love about this metal. In fact, some choose to speed up patination to achieve the elegant antique color of their bronze pieces.

Biofouling is a problem faced by many industries, particularly those that deal with water. It is particularly considered a nuisance in the maritime industry where majority of operation takes place at sea. The damage biofouling can cause to ocean vessels and docks can be enormous and expensive, especially if left to spread for years.
Cause of Biofouling
The main cause of biofouling is the formation of microbial films. Natural laws dictate that microorganisms, such as bacteria and algae, can grow rapidly and colonize surfaces when the right conditions are met. They sequester nutrients from water and quickly convert them into new biomass, which is why growth increment can be easily noticeable.
Biofouling often occurs in industrial systems as these places usually have enough space to support the spread of biofilm. Organisms can grow even faster if the industrial process involves the use of biodegradable substances. In the case of ships and docks, their constant exposure to seawater, where all sorts of microorganisms live, is the cause of biofilm development, and eventually biofouling.

Bronze is an absolute favorite when it comes to making decorative fixtures. Whether you need tubes for your customized bed frame or sheets to cover your countertop, bronze is the perfect material. It’s not only an elegant-looking material, but it’s also packed with other properties that attract artisans and builders everywhere. But have you ever wondered how material supplies made of bronze are manufactured? Here’s a glimpse of the process.
There are two ways bronze can be formed into tube, bar, or sheet. One is by casting, a metalworking process in which bronze is melted, poured into mold, and allowed to cool and harden. The other is wrought drawing, which involves heating a block of bronze and working it with tools until the desired shape is achieved. Both techniques have their share of benefits, but you need to choose the one that works better for your needs. Here are some of their prominent differences.

Copper is one of the most widely used metals in the world. It is so well-known that even with the discovery of other metals of similar versatility and value, it is still the material of choice for many manufacturers in their projects. If you are working on something that requires a corrosion-resistant, elegant-looking, or electrically conductive material, copper is surely worth looking at. Here are some facts that might further interest you in using copper.
There’s no doubt that copper is among the oldest types of metal around and the first to be worked and manipulated by man. Countless ancient artifacts made from copper have been dug up and displayed in museums. Perhaps the most popular is a tiny awl found in some ruins in the Middle East that dates as far back as 5100 B.C. Copper has also been recently discovered to have been used in some parts of the Great Pyramids.
Copper was originally used for making coins, weapons, and cookware. Many ancient remains had been found with copper accessories, too. So for a long time, copper had enjoyed the same popularity as gold and silver. Some archeologists even believe that if it’s true that the first civilization already knew how to produce electricity, they would have used copper to harness and transfer it.

Whether you are working on a small project or planning to put up a business that involves the use of metal supplies, you need to find the perfect supplier to partner with. Unfortunately, with so many metal suppliers out there, it can be daunting to find one that is capable of supporting your needs. Here’s a few tips on choosing where to buy copper sheets, tubes, and other materials for your project.
A lot of companies claim to be fully capable of meeting all of their clients’ needs. No matter how convincing they may be, it’s quite easy to tell whether they can really live up to their promise or not. Just ask how many years they’ve been in the business. A few years of experience may seem long but when it comes to supplying building materials, a company needs more than that. If possible, choose a supplier that has more than a few decades of experience providing for all kinds of business.

Decomposition is a natural process that affects both living and non-living things. You may think that only organic objects decay and return to dust after expiring, but in truth, even the inorganic ones are fated to deteriorate eventually. They only follow a rather different decomposition process, which takes longer. Metals, for instance, decompose through corrosion. Some metals rust when exposed to oxygen, while others develop a patina on their surface.
Corrosion comes in a range of forms, each of which is classified by the cause of chemical deterioration. Understanding how each type of corrosion works can help you perform the necessary preventive measure, which would allow you to enhance the durability of your project output. This also helps you carry out the right procedure in case there’s a need to speed up corrosion. Below are the most common types of corrosion that could occur either naturally or purposefully.
This type of corrosion targets all exposed surfaces and occurs at a uniform rate, as the name suggests. It usually takes place when the entire object is exposed to a corrosive chemical compound, for instance, when submerged in saltwater or acid. The most prominent example is rust developing on the surface of structural steel bars. The oxygen from air and moisture that clings to their exposed surface reacts with iron to form iron oxide or rust.

There are two classifications of metal—ferrous (contains iron) and non-ferrous (does not contain iron). Besides having different levels of corrosion resistance—ferrous metals being more susceptible to rusting due to the presence of iron—these two types of metal have many other disparities. One in particular is that non-ferrous metals are more malleable than ferrous metals. This makes them easily worked to suit various applications.
What is malleability?
Malleability is the ability of metals to be hammered, pressed, or rolled into thin sheets without breaking. If you look at the molecular structure of a non-ferrous metal through an electron microscope, you’ll see that it consists of lattices densely stacked on top of each other but are free to slide against each other and easily fill up gaps when placed under stress. Most non-ferrous metals are malleable, yet this property can be adjusted by alloying different metals.
Some of the most popular malleable non-ferrous metals include gold, silver, and copper. For millennia, these metals have been formed into plates and sheets that prove handy for so many applications. Here are some of the applications of metal sheets. Read more from this article: http://www.rotaxmetals.net/sheet-metal-suppliers-what-products-they-offer-and-how-to-utilize-them/.
