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.

Low carbon steel (with carbon content not exceeding 0.25%) is one of the most commonly used types of steel in both industry and daily life, thanks to its excellent plasticity, weldability, and low cost. It is widely applied in components such as pistons, screws, and drive shafts. However, due to its limited strength, it usually requires post-treatment.

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.
