Choosing the right material for milling and turning

[BorisBritva]

When ordering CNC parts, half the success is choosing the right material. Aluminum 6061 is easy to machine and more affordable; 7075 is stiffer and handles higher loads. Stainless 304/316 works in https://www.sppcncmachining.com corrosive environments, but cuts slower and costs more. Brass is great for precise small features and threads. Before sending a drawing to a platform like sppcncmachining.com, clarify the required hardness, operating environment, tolerances, and mass. This eliminates unnecessary re-quotes. Tip: if a part “lives” in a warm enclosure and dimensional stability matters, ask about heat treatment or natural aging of aluminum—it often saves more than you’d expect.
