Brass is the resulting alloy when you combine about 67% copper and 33% zinc. This standard composition can be altered to produce different types of brass. Minute amounts of other metals, such as lead, phosphorus, aluminum, manganese, and silicon can be added to the mixture to further improve the properties of brass. The brass mixture we use in our jewellry do not need to add allergic components such as nickel or lead.
If you are familiar with copper and zinc, it will be easy for you to understand the nature of brass. We know that copper is extremely durable, able to last for thousands of years due to its ability to form patina, a green layer of material that protects its surface from weathering. Zinc, on the other hand, is known for its high corrosion resistance and density, which makes it incredibly impermeable. Now, let’s take a look at brass and its useful properties.
Corrosion Resistance
Like copper, brass is also resistant to corrosion. It’s no wonder manufacturers prefer brass channel and tube products to other metal supplies. With the right composition, brass can even hold out in seawater, which is ten times harsher than tap water. Unfortunately, brass tarnishes quickly, which is why brass furniture and accessories must be regularly polished to stay shiny.
Workable
Standard versions of brass are prized for their malleability. Meaning, they can be molded into different shapes and thicknesses without applying heat. Compared with bronze, brass is easier to cold work, weld, and braze. Adding a little bit more zinc helps improve this metal’s machinability.
High Conductivity
Like copper, brass also has a considerable heat and electrical conductivity, around 40% that of copper. It doesn’t quickly burn under high voltage like silver and other conductive metals. This is why brass is the preferred material for machine parts that function as conductors.
Germicidal Properties
Brass is also anti-bacterial, a property that is characteristic of most non-ferrous metals. Their molecules produce ions that target a certain protein in single-celled microorganisms, resulting in their demise. The entire process takes about two to four hours depending on the type of metal involved. This is the reason why copper alloys, such as brass, are ideal for filtration systems.
Aesthetic Appeal
There’s no denying the majestic appearance of standard brass. Its glittery yellow tone rivals that of authentic gold. Those who are looking for a cheaper alternative to gold in their crafts must consider brass.
How to mantain your brass jewelry
Our Jewelry is made of Alpha Brass, more commonly known as soft brasses, these are brasses with 65% copper and 35% zinc. This much copper is what makes these brasses malleable and easy to work cold. They also look more gold-like than the other forms of brasses.
If, specially by rings, you notice a green patina being formed, that actually very positive cause it is what makes brass resistant. Just cleap that up with a soft cotton cloth and a little bit of Toothpaste. After wash your ring and dry it properly. Thats it, your jewelry is new again.
Another solution that is even better is to find a brass cleaner product in a store (specially the ones specialized in building materials, Like Leroy or Bauhaus in Germany). Apply a bit of it in a clean piece of cotton cloth and rub you jewelry with. After, make it shine polishing with the dry part of the cloth. One bottle of the cleaner would be enough to use for many years to come.
