Magnetite (Fe₃O₄) is strongly magnetic; maghemite (γ-Fe₂O₃) is ferrimagnetic but weaker; common rust (α-Fe₂O₃ hematite) is weakly magnetic at room temperature. Knowing which oxide you have prevents contamination, measurement errors, and rework in CNC machining services and CNC machining factories.
Micro-Arc Oxidation (MAO), also called Plasma Electrolytic Oxidation (PEO), is an advanced surface treatment that uses high-voltage plasma discharges in an electrolyte bath to form a hard, ceramic-like oxide coating on metals such as aluminum, magnesium, and titanium. This process enhances hardness, corrosion resistance, and wear properties, making it ideal for CNC machined parts.
Yes, cobalt is a ferromagnetic metal, meaning it is strongly attracted to magnets and can be magnetized itself. Its robust magnetic properties are primarily due to its electron configuration, specifically the unpaired electrons in its atomic orbitals, which create a net magnetic moment. This inherent characteristic makes cobalt a critical element in various magnetic applications, including high-performance magnets and magnetic recording media. Our cnc machining factory frequently works with materials, including magnetic alloys, that demand an intricate understanding of their properties for precision manufacturing.
Yes, nickel is magnetic. As a ferromagnetic metal, nickel can be attracted to magnets and even retain magnetism under certain conditions. Its magnetism depends on atomic structure, temperature, and alloying elements. This property makes nickel essential in magnetic alloys, sensors, motors, and CNC machined parts for advanced applications.
Steel can be magnetic depending on its composition and structure. Carbon steel and ferritic or martensitic stainless steels are magnetic, while austenitic stainless steels are generally non-magnetic. Heat treatment, alloying, and crystal structure affect steel magnetism. Understanding these properties ensures proper selection for CNC machining parts and industrial applications.
Copper is not magnetic. It is classified as diamagnetic, meaning it weakly repels magnetic fields instead of attracting them. This property comes from its electron structure, making pure copper unsuitable for magnetic applications but highly valuable for conductivity and nonmagnetic environments.
Most metals conduct electricity because of their free electrons. The best conductors are silver, copper, and gold, followed by aluminum and brass. Factors such as temperature, impurities, and alloying can affect conductivity. For precision applications, CNC machining services can help manufacture conductive parts with the right balance of strength and electrical performance.
The key difference between 6061 aluminum T6, T651, and T6511 is stress relief and dimensional stability. T6 is heat-treated and naturally aged, T651 is stress-relieved by stretching, and T6511 is stress-relieved by stretching and minor straightening. These differences affect machinability, performance, and cost for aluminum CNC machined parts.
