Copper alloys

Learn more about copper alloys Did you know that most metals are not used in a pure state, but are mixed with other metals? This process called alloying is based on combining two or more metals to make them harder or more resistant.

The different copper alloys have the same technical characteristics depending on their composition. This makes them suitable for use in numerous objects with very varied applications.

Having described the above, we can conclude that one of the main alloys of copper is bronze, which is obtained when we add tin to copper. This alloy, which has 75% to 88% copper, is characterized by having:

• Yellowish color
• Resistance to atmospheric agents.
• Resistance to mechanical stress.

Other copper alloys

There are other metal alloys that stand out for their unique properties, such as aluminum bronze, which, as its name suggests, is the result of adding aluminum to copper. This combination of metals not only enhances the mechanical characteristics of each, but also creates a strong and versatile alloy.

El origin of bronze to aluminum It dates back to ancient China, where its ability to maintain a distinctive luster was discovered, making it ideal for making decorative and utilitarian objects. Over time, this alloy has demonstrated exceptional resistance to corrosion, even when exposed to a variety of harsh atmospheric conditions, such as marine or industrial environments. This resistance, coupled with its durability, makes it a material of choice for applications requiring longevity and reliability.

Among its main uses Of the copper alloys today we find the manufacturing of aircraft landing gear, a critical application in the aerospace industry due to the mechanical demands faced by this part of the aircraft. Aluminum bronze stands out in this sector thanks to its combination of corrosion resistance and your ability to withstand high loads, ensuring optimal performance under extreme conditions, such as landing on various runways and constant exposure to the elements. However, its use is not limited exclusively to aeronautics.

At metal-mechanical industryThis alloy is also valued for its superior mechanical properties. It is used in the manufacture of gears, bushings and other parts that must resist wear and friction under demanding conditions.

As for the standards governing specifications techniques for copper alloys, it is important to refer to international standards that establish the quality requirements for products manufactured from copper alloys. One of the most important is the ASTM B505 standard, which specifies the requirements for Continuous cast rods, bars, tubes and profiles manufactured from this type of alloy. This standard ensures that the materials meet the necessary criteria in terms of composition, mechanical properties and corrosion resistance, thus guaranteeing their performance in various industrial and structural applications.

Copper alloys, in addition to their durability and resistance, have a adequate machinability, which facilitates its manipulation in industrial processes, allowing it to be formed in a wide variety of shapes and sizes, such as specialized tubes, bars or profilesThis makes it a versatile and valuable option for engineers and designers looking for materials capable of withstanding demanding conditions without compromising structural integrity or aesthetic quality.

The manufacture of bronzes under this standard through the continuous casting process can give us the following advantages:

• Free of porosity.
• Greater internal cleaning.
• Better mechanical characteristics.
• Better machinability.
• Closer dimensional tolerances.
• Longer bars.

At Serviacero Especiales, we market Standard bronze, commercial or phosphorous, which has excellent physical advantages, great machining, resistance to tension and effort, recommended for light work, the supply hardness is around ~ 65 HB 10/1000.

Additionally, we distribute Bronze SAE 62, also known as Bronze C90500, It is a bronze recommended for general uses that require: high resistance and heavy work.

It offers great resistance to wear by chemicals and acids, and to corrosion from the environment, the supply hardness is between ~ 75 to 110 HB 10/1000.

While on days Bronze SAE 64, Also known as C93700, it is ideal for heavy duty work, its excellent anti-friction gives it the qualities of a dry lubricant, its supply hardness ranges around ~ 65 HB 10/1000.
