No need for multi-party price comparison or complex selection; upload a 3D model with one click to get an accurate quote and customized solution, helping customers efficiently implement their projects.

8 New Core CNC Machining Materials: Precisely Adapt to Different Harsh Working Conditions

The newly added materials focus on making up for the shortcomings of traditional materials such as insufficient high-temperature resistance, weak corrosion resistance, and high processing difficulty. Each material has undergone strict quality inspection, suitable for mass production and precision customization. The specific characteristics and application scenarios are clearly available for quick demand matching:

(1) Engineering Plastics

4340 Structural Steel: High-tensile strength structural steel. Compared with 4140 series alloys, its tensile strength is increased by 40%, which can withstand extreme high temperatures, impacts and wear. It is usually supplied in an annealed state (HRC 20) and can be strengthened by heat treatment according to needs. It is suitable for high-end scenarios such as heavy-duty shafts, landing gear, collets, and molds.

HDPE (High-Density Polyethylene): Selected food-grade raw materials, milky white in color, with excellent moisture-proof and chemical corrosion resistance, strong impact resistance, and not easy to age. It is particularly suitable for outdoor equipment casings, waterproof seals, watertight containers and other scenarios. It is easy to process, cost-controllable, and can meet the needs of mass production.

PVC (Polyvinyl Chloride, Type 1): Gray flame-retardant plastic with outstanding insulation performance, acid and alkali resistance, and organic solvent resistance. It also has self-extinguishing properties, no need to add additional flame retardants. It is suitable for electrical insulation parts, liquid contact equipment, flame-retardant equipment casings and other scenarios, with cost performance far exceeding similar materials.

(2) High-Performance Metals

Nitronic 60 (UNS S21800/218 Stainless Steel): High-end and high-performance stainless steel with excellent high-temperature resistance, which can maintain its original strength in environments above 1800°F. Its wear resistance and corrosion resistance are far superior to 304 series stainless steel, and it is non-magnetic. It is the preferred material for aerospace flight components and high-temperature working condition equipment parts, and material inspection reports can be provided.

440C Stainless Steel: A well-recognized high-hardness stainless steel in the industry. After professional heat treatment, its Rockwell hardness can reach 58-60HRC, with extremely strong wear resistance. Its corrosion resistance is comparable to 304 stainless steel, no complex subsequent processing is required. It is suitable for bearings, precision tools, high-wear mechanical parts and other scenarios, and its service life is more than 30% longer than ordinary stainless steel.

410 Stainless Steel: The most commonly used economical stainless steel in the 400 series, with good wear resistance and corrosion resistance. Its performance can be further enhanced through heat treatment, and it is magnetic. It is suitable for fasteners, tools, nozzles, general tools and other scenarios. Exclusive discounts are available for bulk purchases, and the delivery cycle is short.

1215 Carbon Steel: Free-cutting carbon steel. Compared with traditional 1018 carbon steel, its processing efficiency is increased by 25%, with high surface finish and no obvious processing tool marks. No additional polishing is required. It is suitable for precision instrument parts, small structural parts, and mass-produced hardware accessories, with extremely high cost performance.

4140PH Chromium-Molybdenum Steel: Pre-hardened (HRC 28-32), no subsequent thermal processing is required, which effectively avoids stress fracture problems. It has high strength and good toughness, suitable for gears, couplings, tool holders, precision shaft parts and other components. It can be directly put into processing, shortening the project cycle.

4 New Surface Finishing Processes: Empower Part Performance and Extend Service Life

High-quality surface finishing can not only improve the appearance texture of parts but also greatly enhance wear resistance, rust resistance, self-lubrication, and reduce later maintenance costs. The 4 newly added high-end processes all meet international industry standards and are suitable for different materials and working conditions:

• PTFE-Impregnated Hard Anodizing: Designed specifically for aluminum alloy and titanium alloy parts, PTFE (Teflon) is embedded into the hard anodized layer to form a self-lubricating dry contact surface. It not only has the protective performance of Type 3 hard anodizing but also reduces part friction loss. It meets the AMS-2482 Type 1 (MIL-A-63576 Type 1) standard, with a black appearance, suitable for precision mechanical moving parts, and its service life is extended by more than 50%.
• Titanium Anodizing (Tiodize): Strictly follows the AMS-2488 Type 2 standard, which can significantly improve the fatigue strength and wear resistance of titanium alloy parts. The non-pigmented coating has a matte texture and does not affect part precision. It is widely used in high-end fields such as aerospace and medical equipment, and process inspection reports can be provided.
• Tumbling: A batch processing process that quickly removes sharp edges and burrs of parts, eliminates processing tool marks, and improves surface finish through full contact between vibrating media and parts. No manual polishing is required, suitable for small and medium-sized parts (manual review service is available for parts over 8 inches), greatly improving mass production efficiency.
• Zinc Plating: Designed for carbon steel and rust-prone alloy parts, it meets the ASTM B633-15 SC1 standard, with the coating thickness accurately controlled at 0.0002 inches. It has a low silver luster appearance, excellent rust resistance, and controllable cost. It is suitable for mass production scenarios such as general hardware, fasteners, and automotive parts.
