data-end=\"12579\">What is the difference between hot rolled and cold rolled steel?<\/h3>\n<p data-start=\"12581\" data-end=\"12780\">Hot rolled steel is often used for structural parts, while cold rolled steel provides tighter thickness control and a smoother surface, which can be useful for cosmetic enclosures or precision bends.<\/p>\n<h3 data-section-id=\"141t3da\" data-start=\"12782\" data-end=\"12824\">What does ferrous vs non-ferrous mean?<\/h3>\n<p data-start=\"12826\" data-end=\"13024\">Ferrous metals contain iron (most steels).<br data-start=\"12868\" data-end=\"12871\" \/>Non-ferrous metals include aluminum, copper and titanium. The choice affects weight, corrosion resistance and sometimes electrical grounding assumptions.<\/p>\n<h3 data-section-id=\"k9u46r\" data-start=\"13026\" data-end=\"13090\">Which sheet metal processes are most common for electronics?<\/h3>\n<p data-start=\"13092\" data-end=\"13252\">Typical processes include laser cutting, punching, press brake bending, welding, hardware insertion and finishing processes such as powder coating or anodizing.<\/p>\n<h3 data-section-id=\"1aewhci\" data-start=\"13254\" data-end=\"13329\">When should CNC machined aluminum parts be used instead of sheet metal?<\/h3>\n<p data-start=\"13331\" data-end=\"13454\">Machining is often selected when parts require precise 3D geometry, flat thermal interfaces or tight mechanical tolerances.<\/p>\n<h3 data-section-id=\"cu430m\" data-start=\"13456\" data-end=\"13522\">How can metal costing be reduced without compromising quality?<\/h3>\n<p data-start=\"13524\" data-end=\"13673\">Using standard material thicknesses, improving nesting efficiency, reducing hardware variety and applying early DFM reviews can help stabilize costs.<\/p>\n<\/section>\n<footer style=\"background: #2d5797; padding:
