5052 O H112 Marine Grade Aluminum Bar

5052 O H112 Marine Grade Aluminum Rod is a rod made from 5052 aluminum alloy that is fully annealed to improve workability and tempered to provide strength and resistance suitable for marine applications.

5052: Indicates alloy composition. In this case, it's mostly aluminum with smaller amounts of magnesium and chromium. 5052 aluminum is known for its strength and corrosion resistance.

O: The "O" designation refers to the tempered or annealed state of aluminum. In this case, "O" stands for annealed, indicating that the aluminum has been sufficiently annealed to improve its machinability and reduce internal stresses.

H112: This is another status name. "H112" means the aluminum has been strain hardened and stabilized. This is a common condition for marine grade aluminum and provides good strength and resistance to the marine environment.
