What Are Bronze Alloys?
In spite of its high cost, bronze is one of the strongest and most durable metals. It is highly sought after in the building industry due to its inherent characteristics and incomparable grace and beauty. A mixture of tin and aluminium, bronze has been used as an alloy for making pipes and pots since the time of the Romans. Its use as a metal for artistic purpose dates back to ancient Greece. Bronze has found its way into contemporary culture too. It has been used for handcrafting ornamental items like statues, weapons, ornamental carvings, plaques, medals, and watches.
As mentioned above, bronze has excellent thermal conductivity and excellent resistance towards corrosion. The reason behind this is that it contains very little amount of nickel or chromium, which makes it highly resistant to the corrosive effect of sulfuric acid. In fact, the very foundation of the usefulness of this alloy is its ability to resist corrosion, which makes it an ideal choice to be used in a variety of industries. Apart from being highly conductive and rust-resistant, it also shows low levels of oxidation and shows very little reactivity towards various chemicals, fats, and fuels, making it a preferred choice for end-use. Additionally, it has good electrical and mechanical properties and possesses good resistance towards stress, compression, temperature, and weight.
Bronze, despite being a non-ferrous metal is still valuable for jewelry and art. Unlike other metallic alloys, tin-plated bronze is quite vulnerable to extreme heat, which can evaporate or weaken the adhesive holding it to the base material. On the other hand, non-metallic bronze is highly valued for its high resistance towards corrosion, excellent thermal conductivity, and non-magnetic properties. Due to its metallic properties, it can be used for various electrochemical applications such as soldering, brazing, soldering of stainless steel, use in friction and vibration control, etc. Bronze is used for shaping as well, as it's the most common choice for designing musical instruments as well as for carving.
Another type of alloy that has caught on in the world of bearings alloys is lead-free bronze. Lead is highly poisonous, which means its use involves a lot of risk. In addition, its high temperature cause irreparable damages to the internal parts of electronic circuits, causing catastrophic failures. However, the cost of leaded tin bronzes is far lesser than the price of the electronic components they will be replacing. Besides, there are also other uses for these bronze alloys, which make them a good investment.
The range of available grades for this type of alloy depends on its chemical composition, which determines its melting point. For example, a higher percentage of tin has a lower melting point than that of lead, whereas higher percentages of copper have a higher melting point than that of lead. Thus, one can find bronze alloys having a range of temperatures between tin and lead. A very important feature of this type of alloy is that it has a high alloyability, which allows it to be manufactured into various shapes without changing its composition.
The properties of this metal allow it to be machinable by hand, by using complex machinery, or even by using specialized equipment. Unlike other alloys, bronze has a unique combination of hardness and softness, which results in its being very elastic and ductile. Its ductility allows it to be formed into various hard-edged surfaces, such as bronze sculptures, while its hardness imparts a certain amount of wear resistance to the parts they're being used on. Due to these properties, these alloys are often used in applications where wear resistance is a major factor, as they are very effective at resisting impact and heat.
