2025 08 18 Iron comes in multiple forms—pure iron, pig iron, wrought iron, cast iron, stainless steel, carbon steel, alloy steel, tool steel, ductile iron, and gray cast iron. Each has distinct properties and applications. Understanding their differences ensures optimal material selection for construction, manufacturing, and CNC machined parts production.

VMT 2025 08 15 6061-T6 is heat-treated aluminum without stress relief, 6061-T651 is stress-relieved T6 for improved stability, and 6061-T6511 is stress-relieved with controlled straightness for extruded shapes. Choosing depends on dimensional tolerance needs, part size, and machining requirements.

VMT 2025 08 14 Yes, carbon steel is generally magnetic because it contains iron, a ferromagnetic material. Its magnetism depends on carbon content, crystal structure, and heat treatment. Most carbon steels used in CNC machining parts will strongly attract magnets, making them suitable for applications requiring magnetic properties.

VMT 2025 08 13 Titanium is not magnetic under normal conditions. It is a weakly magnetic (diamagnetic) metal, meaning it is not attracted to magnets. Its atomic structure prevents strong magnetic alignment, making it ideal for applications like medical implants, aerospace components, and precision CNC machined parts that require minimal magnetic interference.

VMT 2025 08 12 Brass is generally non-magnetic because it is an alloy of copper and zinc, both of which are non-ferromagnetic. However, trace impurities or mechanical processing can induce slight magnetism. To ensure non-magnetic performance in brass CNC machined parts, choose high-purity alloys and verify properties before production.

VMT 2025 08 11 Yes, iron is magnetic because it is a ferromagnetic metal. Its unpaired electrons and aligned magnetic domains make it strongly attracted to magnets. Pure iron and many iron-based alloys retain magnetism, but some stainless steels and high-temperature conditions can reduce or eliminate this property.

VMT 2025 08 08 To tap a standard 3/8-16 thread, use a 5/16 inch (0.3125") drill bit. This size ensures a proper thread engagement and minimizes the risk of stripping or tool wear, especially when producing CNC machining parts across various materials.
