Aluminum: The King of Versatility
Aluminum alloys, particularly 6061 and 7075, are the workhorses of CNC machining. Renowned for an excellent strengthtoweight ratio, good corrosion resistance, and superb machinability, aluminum allows for highspeed production of complex parts with exceptional surface finishes. Its thermal and electrical conductivity makes it ideal for heat sinks, enclosures, and lightweight structural components. For projects demanding rapid turnaround and costeffectiveness without sacrificing quality, aluminum is often the premier choice.

Stainless Steel: The Epitome of Strength and Resilience
When applications require superior strength, wear resistance, and corrosion stability, stainless steel alloys like 304 and 316 come to the fore. These materials excel in harsh environments, making them perfect for medical instruments, food processing equipment, and marine components. While machining stainless steel requires robust tooling and expertise to manage its toughness and workhardening tendencies, the result is a durable, longlasting part capable of withstanding extreme operational demands.

Engineering Plastics: Precision for Specialized Needs

Beyond metals, engineering plastics such as PEEK, Delrin (Acetal), and Nylon offer unique advantages. They provide excellent chemical resistance, electrical insulation, and low friction coefficients. CNCmachined plastics are indispensable for insulators, bearings, and prototypes where weight, corrosion, or magnetism are concerns. A proficient machining partner understands the specific thermal and mechanical handling required for plastics to prevent warping and ensure dimensional accuracy.

Titanium: The HighPerformance Champion
For the most demanding applications in aerospace, medical implants, and highstress automotive parts, titanium stands unmatched. Alloys like Ti6Al4V offer an unparalleled strengthtoweight ratio, exceptional corrosion resistance, and biocompatibility. Machining titanium is a significant challenge due to its low thermal conductivity and high chemical reactivity, requiring specialized toolpaths, coolants, and extensive experience. Successfully producing titanium components signifies a machine shop's peak capability and commitment to tackling highvalue projects.
