Metals and Alloys: The Backbone of Precision Parts

Aluminum: Arguably the most popular CNC machining material, aluminum alloys like 6061 and 7075 are prized for their excellent strengthtoweight ratio, good corrosion resistance, and superb machinability. They are ideal for aerospace components, automotive parts, and consumer electronics enclosures, where reducing weight without sacrificing integrity is paramount.

Stainless Steel: Known for its exceptional strength and resistance to corrosion and heat, stainless steel (e.g., 304 and 316) is a goto for medical instruments, food processing equipment, and marine applications. While harder to machine than aluminum, it provides unparalleled durability for demanding environments.

Carbon Steel: For applications requiring high strength and toughness, carbon steel alloys like 1045 and 4140 are excellent choices. They are commonly used for functional prototypes, gears, shafts, and other industrial machinery components.

Brass: This alloy offers excellent machinability, leading to fast production times and a highquality surface finish. Its natural corrosion resistance and electrical conductivity make it perfect for plumbing fittings, electrical components, and decorative hardware.

Engineering Plastics: Versatility and Specialization



Delrin (POM): A robust acetal resin, Delrin is known for its high stiffness, low friction, and excellent dimensional stability. It is often used to create gears, bearings, and insulators that require minimal moisture absorption.

Nylon (PA): Valued for its good wear resistance, toughness, and fatigue resistance, Nylon is a versatile plastic for parts like bushings, rollers, and structural components.

PEEK: A highperformance thermoplastic, PEEK can withstand extreme temperatures, is chemically resistant, and is biocompatible. These properties make it essential for the aerospace, automotive, and medical industries.

ABS: Known for its good impact strength and machinability, ABS is frequently used for prototypes, housings, and consumer products.
