Aluminum
Aluminum is a popular material for constructing firearm suppressors due to its light weight, durability, and corrosion resistance. However, not all types of aluminum are suitable for suppressors. Let's take a closer look at the different types of aluminum and their characteristics as they relate to firearm suppressors.
6061-T6 Aluminum: This is the most commonly used aluminum alloy for suppressors due to its excellent balance of strength, weight, and cost. It is a general-purpose alloy that is heat-treatable and has good corrosion resistance. Suppressors made from 6061-T6 are suitable for use with most pistol and rifle calibers up to .300 Blackout.
7075-T6 Aluminum: This alloy is stronger and more durable than 6061-T6, but it is also more expensive. It is often used for high-pressure applications, such as in the aerospace industry, but its use in suppressors is less common.
2024 Aluminum: This alloy is not recommended for use in suppressors due to its poor corrosion resistance. It is commonly used in aircraft construction, but it is not suitable for use in a suppressor that will be exposed to corrosive gases.
Overall, aluminum suppressors are popular due to their lightweight construction, which makes them ideal for use on handguns and lightweight rifles. The weight savings achieved with an aluminum suppressor can make a significant difference in the handling and balance of a firearm.
In terms of durability, aluminum suppressors are not as rugged as their steel or titanium counterparts, but they can still withstand a significant amount of use. They are best suited for recreational shooting, where they will not be subjected to sustained fire or heavy use.
Aluminum suppressors are also cost-effective when compared to suppressors made from steel or titanium. This makes them an attractive option for shooters who are looking for a high-quality suppressor without breaking the bank.
In terms of specific applications, aluminum suppressors are best suited for use with pistols and rifles chambered in calibers up to .300 Blackout. They are not recommended for use with high-pressure calibers such as .308 Winchester or .338 Lapua.
