Comparison of CNC Machining Materials

ABS (Acrylonitrile-Butadiene-Styrene Copolymer) is a well-balanced engineering plastic with good mechanical properties, excellent impact resistance, and easy processability. These characteristics have led to its widespread application in fields such as consumer electronics, household appliances, automotive industry, and daily necessities.

Titanium alloys are high-performance materials that combine exceptional strength, a superior strength-to-weight ratio, outstanding corrosion resistance, high-temperature stability, and excellent biocompatibility. While costlier and more difficult to process than steels or aluminum alloys, their unique advantages—high strength, light weight, and durability in extreme environments—make them indispensable in aerospace, advanced medical, and deep-sea applications, where performance takes priority over cost.

Stainless Steel 17-4PH is a high-performance martensitic precipitation hardening stainless steel, featuring excellent corrosion resistance and high strength, making it suitable for a wide range of industrial applications. Its chemical composition and physical properties enable its extensive use in fields such as aerospace, chemical engineering, marine engineering, food processing, and nuclear industry. Through appropriate heat treatment processes, its mechanical properties and corrosion resistance can be further optimized.

stainless steel 304 is also known as 18/8 stainless steel, which contains approximately 18% chromium (Cr) and 8% nickel (Ni). It not only possesses excellent oxidation resistance and corrosion resistance, but also has good workability and surface quality. Currently, it is the most widely used stainless steel grade in industrial manufacturing and civil applications.

Aluminum 7075 alloy is a high-strength wrought alloy with zinc as its primary alloying element. It exhibits excellent mechanical properties, characterized by outstanding strength, toughness, and fatigue resistance. In addition, compared with most aluminum alloys, it demonstrates superior corrosion resistance, which makes it widely used in aerospace and other fields where lightweight structures and comprehensive performance are critically required.
