Přehled

Let’s start with an overview of what hliníkový bronz is and why it’s such a popular choice across multiple industries.

What is Aluminum Bronze?

Aluminum bronze is a group of copper-based alloys that include aluminum as the primary alloying element. The aluminum content typically ranges from 5% to 11%, which gives the alloy its unique properties. Other elements such as iron, nickel, manganese, and silicon can also be added to further enhance its performance.

So, why do we care so much about aluminum bronze? It offers an impressive blend of koroze odolnost, vysoká pevnost, a odolnost proti opotřebení, all while maintaining excellent obrobitelnost a tepelná vodivost. It’s often favored in environments where both síla a odolnost vůči drsným podmínkám are critical, such as in the marine, chemical, and aerospace industries.

Klíčové vlastnosti :

• Vysoká pevnost and toughness
• Vynikající odolnost proti korozi, especially in marine and chemical environments
• Dobrá odolnost proti opotřebení and low friction coefficient
• Nemagnetické properties, making it ideal for certain sensitive applications
• Tepelná a elektrická vodivost, though lower than pure copper

Aluminum bronze is often compared to other types of bronze (like phosphor bronze or silicon bronze) and even steel alloys. What sets it apart is its odolnost proti korozi, particularly in environments where slaná voda nebo expozice chemickým látkám is common. This makes it particularly useful in marine hardware, pumps, and valves, and even in aerospace applications where reliability and durability are paramount.

Složení a vlastnosti

Porozumění složení of aluminum bronze is critical to understanding its performance. As mentioned earlier, aluminum is the primary alloying element, but other metals are often added to improve specific properties like síla, tvárnost, nebo odolnost proti korozi.

Typical Composition of Aluminum Bronze Alloys

Note: The specific composition can vary slightly depending on the manufacturer and the intended application.

Mechanické vlastnosti

The mechanical properties of aluminum bronze make it an excellent choice for high-stress, high-wear environments. Below is a breakdown of the typical mechanical properties of some common aluminum bronze alloys.
