Finer aluminum powder sizes produce higher consolidated strength values approaching wrought alloys. Heat treatability also boosts mechanical performance.<\/p>\n\n\n\n

Manufacturing Method<\/strong><\/h2>\n\n\n\n
<\/th><\/th><\/tr><\/thead>
Atomization<\/strong><\/td>Gas or water atomization from molten alloy produces fine spherical powders<\/td><\/tr>

Alloying<\/strong><\/td>Direct alloying or ad-mixing elemental\/pre-alloyed base powders<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

Gas atomization allows the most precise property control while milling increases shape complexity and internal porosity. AM suitable powders utilize atomization but maintain flowability.<\/p>\n\n\n\n
