ASTM B26/B26M-18e1

Annotation of standard text ASTM B26/B26M-18e1 :

This specification covers aluminum alloy sand castings except those that are for aerospace applications. The chemical compositions are determined in accordance with the specified suitable chemical and spectrochemical test methods. Addition of small amounts of modifiers and grain refining elements to the molten alloys from the remelting furnace is permitted before casting. Pure metals, recycled materials, and master alloys can also be used to make the alloys as long as the chemical composition can be analyzed and adjusted to conform to the requirements prior to pouring any casting. Castings should only be repaired using approved processes such as welding, impregnation, peening, blending, soldering, and so forth.
