Decoding the H112 Temper
When you see "H112," you are looking at a designation that conforms to strict tempering guidelines defined in specific industrial standards such as ASTM B209. This temper indicates that the aluminum sheet has been given a solution heat treatment and then aged naturally, portraying a state of reduced internal stresses, which provides a platform for excellent workability.
Clients often choose H112 temper due to its versatility—during processing or fabricating operations such as welding, forming, stamping, or cutting, the H112 temper alleviates worries about brittleness, retaining foam properties without sacrificing structural integrity.
Implementation Standards
The marine and defense water transportation industries frequently opt for 5083 H112 aluminum sheets, primarily due to standards emphasizing safety, resilience, and longevity. This means meeting various implementation specifications:
- ASTM B209: Specification for Aluminum and Aluminum Alloys Sheet and Plate.
- ISO 6361-2: Aluminum and Aluminum Alloys – Sheet and Plate – Part 2.
- EN 573: Series Aluminum and Aluminum Alloys – Chemical Composition (inclusive of wrought alloys).
In recognizing and adhering to these standards, manufacturers ensure that 5083 H112 aluminum sheets can easily operate in demanding environments, retaining generous yield strength across temperatures.
