Custom Stainless Steel Kitchen Sink, Double-Sink Stamping Molds

Steel is the most widely used metal material in machining, and comparing the performance of its subcategories is crucial. Carbon structural steel is inexpensive and has excellent machinability, making it suitable for machining general-purpose parts with low strength requirements, such as bushings and bolts. However, this type of steel has weak corrosion resistance and is prone to rusting in humid or acidic/alkaline environments, limiting its application scenarios. Alloy steel, by adding elements such as chromium, nickel, and molybdenum, significantly improves its strength and heat resistance, becoming the first choice for high-load components such as gears and crankshafts. However, it is more difficult to machine and requires specialized tools to ensure machining accuracy.

Aluminum alloys, with their lightweight and easy-to-form advantages, have become a favorite in aerospace, automotive electronics, and other fields. Its density is only one-third that of steel, significantly reducing product weight. It also does not easily produce built-up edge during cutting, resulting in much higher machining efficiency than steel. However, aluminum alloys have lower hardness and insufficient wear resistance. If used for parts subjected to frequent friction, additional surface hardening treatment is required; otherwise, wear and deformation are likely to occur.

Copper alloys, with their excellent electrical and thermal conductivity, occupy an irreplaceable position in the machining of electrical and heat dissipation components. Brass has excellent machinability, with smooth chip breaking during machining, making it suitable for manufacturing precision parts such as valves and pipe fittings; bronze has superior strength and wear resistance, and is often used to make wear-resistant components such as bearings and worm gears.

Engineering plastics are a core category of machined non-metallic materials, and the performance differences between different plastics are significant. ABS plastic has good toughness and ease of processing, making it suitable for manufacturing exterior parts such as shells and panels. It is not prone to cracking during processing, and its surface is easy to paint and electroplate; however, ABS has poor heat resistance and is prone to softening and deformation under prolonged exposure to high temperatures, making it unsuitable for high-temperature components.
