Cast Aluminium Alloys Summary

To be clear, this is a structured break down of all the cast aluminium alloys available, however, there are some of these that we do not cast. For a break down on all the cast aluminium alloys we manufacture, please go to either Our Most Popular Alloys or Cast Aluminium Alloy we Produce

Introduction

Aluminum is a metal that can be combined with specific amounts of other elements including copper, magnesium, silicon, zinc, and manganese, to alter its mechanical and physical qualities, making it suitable for different applications. If you mix aluminum with magnesium, you’ll get a strong and lightweight alloy that’s great for use in aerospace and automotive. It has low density, is corrosion resistant, and has good thermal conductivity. Their low weight makes them ideal for use in areas where reduced weight is important. A natural oxide layer forms on the aluminum alloy’s surface, making it corrosion resistant and keeping it protected in all different environments. In spite of their low density, they are strong and durable, factors that make them useful in projects where strength and weight have to be carefully balanced. Aluminium alloys are characterisd by being:

• Relatively Lightweight.
• Resistance to Corosion.
• Have a high strength to weight ratio.
• Formable and malleable.

Aluminum alloys do have some limitations. For one, they have a lower melting point than most other structural metals, which means they won’t be the best fit for high-temperature tasks. They’re not as hard as other metals, so won’t likely survive as much wear and tear. Certain alloys can also be quite expensive, so they might not be as cost-effective as other materials in certain situations.

The Aluminium Designations

Aluminum alloys come in seven different categories, according to their chemical makeup, primary alloying elements, and physical characteristics. These are::
