Hardened Aluminum Alloys. In 1901, German metallurgist Alfred Wilm was working to harden aluminum-copper alloys. The work was not going well so in frustration he went on holiday (vacation). Upon his return, he found a harder material and after many years of work developed a commercially viable age-hardened aluminum alloy.
series alloys contain amounts of soluble elements that far exceed solid-solubility limits. In these alloys, the phase formed by combination of the excess soluble elements with the aluminum will never be dissolved, although the shapes of the undissolved par- ticles may be changed by partial solution. Most of the heat-treatable aluminum alloy

Jul 23, 2020 Precipitation hardening, also sometimes referred to as artificial aging, is a heat treatment process used to bring some aluminum alloys to maximum hardness when natural aging alone is not enough. It is performed after solution heat treatment is complete and the process allows for the dissolved elements from the prior heat treatment to fully precipitate out.
