AMS 5572 Uses

One of the primary applications of AMS 5572 is in aircraft hydraulic and pneumatic systems. These systems require tubing to withstand high pressures and temperatures while resisting corrosion. AMS 5572 is also used in general-purpose industrial applications, such as chemical processing, oil and gas extraction, and medical devices. Its high strength and corrosion resistance makes it ideal for environments where other metals would fail.

AMS 5572 Hardness

The hardness of AMS 5572 varies depending on the heat treatment applied to the metal. In its annealed state, which means it has been heated and allowed to cool slowly, AMS 5572 has a Rockwell hardness of B85 max. This relatively soft state makes the metal easy to form and machine. If heat is treated to a higher hardness, such as HRC 35-45, AMS 5572 becomes more resistant to wear and abrasion.

AMS 5572 Heat treatment

AMS 5572 can be heat treated to improve its hardness and other properties. One common heat treatment is solution annealing, which involves heating the metal to a high temperature and then rapidly cooling it. This process eliminates any internal stresses in the metal, improving its ductility and toughness. Another heat treatment is precipitation hardening, which involves heating the metal to a specific temperature and holding it for a specific time to allow the formation of small, hard particles. This process increases the metal’s hardness and strength.

AMS 5572 Density

AMS 5572 Density refers to the density of a particular alloy known as AMS 5572. This alloy is known for its high resistance to both oxidation and corrosion, making it a popular choice for a wide range of applications. Understanding the alloy’s density is critical when designing and manufacturing products using AMS 5572. This is because density can impact the material’s strength, durability, and weight, which in turn can affect the end product’s performance. A detailed understanding of AMS 5572 Density can help ensure that products made using this alloy meet the necessary standards for quality and performance.


In summary, AMS 5572 is a stainless steel alloy with excellent corrosion resistance, high strength, and flexibility. Its composition meets stringent aerospace specifications, making it a popular choice for aircraft hydraulic and pneumatic systems. AMS 5572 can be heat treated to improve its properties, and its hardness varies depending on the treatment applied. If you’re looking for a high-performance tubing material that can withstand harsh environments, AMS 5572 is worth considering.
