A typical T6 treatment involves solution heating followed by artificial aging resulting in significant property improvements from precipitation strengthening phenomena.<\/p>\n\n\n\n<p>What surface finishes are possible with AM aluminum parts?<\/p>\n\n\n\n<p>After some machining, grinding, sanding and\/or polishing operations, surface roughness (Ra) values under 10 \u03bcm are attainable for additive manufactured aluminum components depending on the AM process used. More intensive finishing can provide optical grade mirror surfaces. Common finishes include anodizing as well for enhanced corrosion or wear properties combined with coloring options.<\/p>\n\n\n\n<p><a href=\"https:\/\/en.wikipedia.org\/wiki\/3D_printing_processes\" target=\"_blank\" rel=\"noreferrer noopener\">know more 3D printing processes<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Aluminum is a popular metal material choice for additive manufacturing, valued for its high strength-to-weight ratio, excellent corrosion resistance, thermal properties, and mechanical performance.
