T condition quenched and naturally aged temper
T condition refers to the naturally aged state after quenching. It enables 1901 / ABT-101 aluminum alloy to obtain higher strength and hardness, while achieving a good balance among strength, ductility, and resistance to stress corrosion cracking. It is suitable for components requiring structural strength, protective performance, and welding compatibility.
T1 condition quenched and artificially aged temper
T1 condition usually refers to the artificially aged state after quenching. The application of 1901T1 can also be seen in technical materials and welding studies related to 1901 aluminum alloy. For projects requiring a more stable strength level, welding performance verification, or specific engineering performance requirements, the T1 condition should be confirmed according to product form, thickness, applicable standards, and project technical documents.
Artificial aging
When a project requires a specific strength level or more stable performance condition, 1901 / ABT-101 aluminum alloy can be artificially aged according to the specific semi-finished product type and technical document requirements. The specific aging process should be confirmed based on product form, thickness, performance targets, and project standards.
Mechanical properties of 1901 aluminum alloy
The mechanical properties of 1901 / ABT-101 aluminum alloy vary by temper, heat treatment, thickness, and product form. Material selection should confirm not only the alloy grade, but also the temper, product type, and project acceptance requirements.
